Convert an arbitrarily-long digit string from one numeric base to another, optionally zero-padding to a minimum column width.

Supports base 2 through 36; digit values 10-36 are represented as lowercase letters a-z. Input is case-insensitive.

Deprecated:
since 1.27 Use Wikimedia\base_convert() directly
Parameters
string$inputInput number
int$sourceBaseBase of the input number
int$destBaseDesired base of the output
int$padMinimum number of digits in the output (pad with zeroes)
bool$lowercaseWhether to output in lowercase or uppercase

string|bool The output number as a string, or false on error

Definition at line 2677 of file GlobalFunctions.php.

◆ wfBaseName()

wfBaseName (   $path,
  $suffix = '' 
)

Return the final portion of a pathname.

Reimplemented because PHP5's "basename()" is buggy with multibyte text. https://bugs.php.net/bug.php?id=33898

PHP's basename() only considers '\' a pathchar on Windows and Netware. We'll consider it so always, as we don't want '\s' in our Unix paths either.

Parameters
string$path
string$suffixString to remove if present
Returns
string

Definition at line 2600 of file GlobalFunctions.php.

◆ wfBoolToStr()

wfBoolToStr (   $value)

Convenience function converts boolean values into "true" or "false" (string) values.

Parameters
bool$value
Returns
string

Definition at line 2975 of file GlobalFunctions.php.

Referenced by LocalSettingsGenerator\__construct(), ApiRsd\formatRsdApiList(), LocalSettingsGenerator\getDefaultText(), MysqlInstaller\getLocalSettings(), and GlobalTest\testClientAcceptsGzipTest().

◆ wfCanIPUseHTTPS()

Returns
bool

Definition at line 3364 of file GlobalFunctions.php.

Referenced by LoginSignupSpecialPage\execute(), Preferences\profilePreferences(), and User\requiresHTTPS().

◆ wfCgiToArray()

wfCgiToArray (   $query)

This is the logical opposite of wfArrayToCgi(): it accepts a query string as its argument and returns the same string in array form.

This allows compatibility with legacy functions that accept raw query strings instead of nice arrays. Of course, keys and values are urldecode()d.

Parameters
string$queryQuery string
Returns
string[] Array version of input

Referenced by Linker\link(), Linker\makeBrokenImageLinkObj(), SpecialChangeEmail\onSuccess(), OutputPage\returnToMain(), LoginHelper\showReturnToPage(), SpecialCreateAccount\successfulAction(), GlobalTest\testCgiRoundTrip(), and GlobalTest\testCgiToArray().

◆ wfClearOutputBuffers()

wfClearOutputBuffers ( )

More legible than passing a 'false' parameter to wfResetOutputBuffers():

Clear away output buffers, but keep the Content-Encoding header produced by ob_gzhandler, if any.

This should be used for HTTP 304 responses, where you need to preserve the Content-Encoding header of the real result, but also need to suppress the output of ob_gzhandler to keep to spec and avoid breaking Firefox in rare cases where the headers and body are broken over two packets.

Definition at line 1902 of file GlobalFunctions.php.

Referenced by ApiMain\checkConditionalRequestHeaders(), and OutputPage\checkLastModified().

◆ wfClientAcceptsGzip()

wfClientAcceptsGzip (   $force = false)

Whether the client accept gzip encoding.

Uses the Accept-Encoding header to check if the client supports gzip encoding. Use this when considering to send a gzip-encoded response to the client.

Parameters
bool$forceForces another check even if we already have a cached result.
Returns
bool

Returns
string|bool String when in read-only mode; false otherwise
Since
1.27

Definition at line 1348 of file GlobalFunctions.php.

Referenced by FileBackendGroup\initFromGlobals(), and JobQueueGroup\singleton().

◆ wfCountDown()

wfCountDown (   $seconds)

For use in command-line scripts.

Parameters
int$seconds

Definition at line 3046 of file GlobalFunctions.php.

◆ wfDebug()

wfDebug (   $text,
  $dest = 'all',
array  $context = [] 
)

Sends a line to the debug log if enabled or, optionally, to a comment in output.

In normal operation this is a NOP.

Controlling globals: $wgDebugLogFile - points to the log file $wgDebugRawPage - if false, 'action=raw' hits will not result in debug output. $wgDebugComments - if on, some debug items may appear in comments in the HTML output.

Since
1.25 support for additional context data
Parameters
string$text
string | bool$destDestination of the message:
  • 'all': both to the log and HTML (debug toolbar or HTML comments)
  • 'private': excluded from HTML output For backward compatibility, it can also take a boolean:
  • true: same as 'all'
  • false: same as 'private'
array$contextAdditional logging context data

◆ wfDebugLog()

wfDebugLog (   $logGroup,
  $text,
  $dest = 'all',
array  $context = [] 
)

Send a line to a supplementary debug log file, if configured, or main debug log if not.

To configure a supplementary log file, set $wgDebugLogGroups[$logGroup] to a string filename or an associative array mapping 'destination' to the desired filename. The associative array may also contain a 'sample' key with an integer value, specifying a sampling factor. Sampled log events will be emitted with a 1 in N random chance.

Since
1.23 support for sampling log messages via $wgDebugLogGroups.
1.25 support for additional context data
1.25 sample behavior dependent on configured $wgMWLoggerDefaultSpi
Parameters
string$logGroup
string$text
string | bool$destDestination of the message:
  • 'all': both to the log and HTML (debug toolbar or HTML comments)
  • 'private': only to the specific log if set in $wgDebugLogGroups and discarded otherwise For backward compatibility, it can also take a boolean:
  • true: same as 'all'
  • false: same as 'private'
array$contextAdditional logging context data

◆ wfIniGetBool()

wfIniGetBool (   $setting)

Safety wrapper around ini_get() for boolean settings.

The values returned from ini_get() are pre-normalized for settings set via php.ini or php_flag/php_admin_flag... but not for those set via php_value/php_admin_value.

It's fairly common for people to use php_value instead of php_flag, which can leave you with an 'off' setting giving a false positive for code that just takes the ini_get() return value as a boolean.

To make things extra interesting, setting via php_value accepts "true" and "yes" as true, but php.ini and php_flag consider them false. :) Unrecognized values go false... again opposite PHP's own coercion from string to bool.

Luckily, 'properly' set settings will always come back as '0' or '1', so we only have to worry about them and the 'improper' settings.

I frickin' hate PHP... :P

Parameters
string$setting
Returns
bool

◆ wfParseUrl()

wfParseUrl (   $url)

parse_url() work-alike, but non-broken.

Differences:

1) Does not raise warnings on bad URLs (just returns false). 2) Handles protocols that don't use :// (e.g., mailto: and news:, as well as protocol-relative URLs) correctly. 3) Adds a "delimiter" element to the array (see (2)). 4) Verifies that the protocol is on the $wgUrlProtocols whitelist. 5) Rejects some invalid URLs that parse_url doesn't, e.g. the empty string or URLs starting with a line feed character.

Parameters
string$urlA URL to parse
Returns
string[]|bool Bits of the URL in an associative array, or false on failure. Possible fields:
  • scheme: URI scheme (protocol), e.g. 'http', 'mailto'. Lowercase, always present, but can be an empty string for protocol-relative URLs.
  • delimiter: either '://', ':' or '//'. Always present.
  • host: domain name / IP. Always present, but could be an empty string, e.g. for file: URLs.
  • user: user name, e.g. for HTTP Basic auth URLs such as http://user:pass@example.com/ Missing when there is no username.
  • pass: password, same as above.
  • path: path including the leading /. Will be missing when empty (e.g. 'http://example.com')
  • query: query string (as a string; see wfCgiToArray() for parsing it), can be missing.
  • fragment: the part after #, can be missing.

◆ wfResetOutputBuffers()

wfResetOutputBuffers (   $resetGzipEncoding = true)

Clear away any user-level output buffers, discarding contents.

Suitable for 'starting afresh', for instance when streaming relatively large amounts of data without buffering, or wanting to output image files without ob_gzhandler's compression.

The optional $resetGzipEncoding parameter controls suppression of the Content-Encoding header sent by ob_gzhandler; by default it is left. See comments for wfClearOutputBuffers() for why it would be used.

Note that some PHP configuration options may add output buffer layers which cannot be removed; these are left in place.

Parameters
bool$resetGzipEncoding

◆ wfUrlencode()

wfUrlencode (   $s)

We want some things to be included as literal characters in our title URLs for prettiness, which urlencode encodes by default.

According to RFC 1738, all of the following should be safe:

;:&=$-_.+!*'(),

RFC 1738 says ~ is unsafe, however RFC 3986 considers it an unreserved character which should not be encoded. More importantly, google chrome always converts %7E back to ~, and converting it in this function can cause a redirect loop (T105265).

But + is not safe because it's used to indicate a space; &= are only safe in paths and not in queries (and we don't distinguish here); ' seems kind of scary; and urlencode() doesn't touch -_. to begin with. Plus, although / is reserved, we don't care. So the list we unescape is:

;:$!*(),/~

However, IIS7 redirects fail when the url contains a colon (see T24709), so no fancy : for IIS7.

%2F in the page titles seems to fatally break for some reason.

string$s

◆ wfUseMW()

wfUseMW (   $req_ver)

This function works like "use VERSION" in Perl except it checks the version of MediaWiki, the program will die with a backtrace if the current version of MediaWiki is less than the version provided.

This is useful for extensions which due to their nature are not kept in sync with releases

Note: Due to the behavior of PHP's version_compare() which is used in this function, if you want to allow the 'wmf' development versions add a 'c' (or any single letter other than 'a', 'b' or 'p') as a post-fix to your targeted version number. For example if you wanted to allow any variation of 1.22 use ‘wfUseMW( '1.22c’ )‘. Using an 'a’ or 'b' instead of 'c' will not result in the same comparison due to the internal logic of version_compare().

perldoc -f use
Deprecated:

Parameters

wfUsePHP (   $req_ver)

◆ wfWaitForSlaves()

wfWaitForSlaves (   $ifWritesSince = null,
  $wiki = false,
  $cluster = false,
  $timeout = null 
)

Waits for the replica DBs to catch up to the master position.

Use this when updating very large numbers of rows, as in maintenance scripts, to avoid causing too much lag. Of course, this is a no-op if there are no replica DBs.

By default this waits on the main DB cluster of the current wiki. If $cluster is set to "*" it will wait on all DB clusters, including external ones. If the lag being waiting on is caused by the code that does this check, it makes since to use $ifWritesSince, particularly if cluster is "*", to avoid excess overhead.

Never call this function after a big DB write that is still in a transaction. This only makes sense after the possible lag inducing changes were committed.

Parameters
float | null$ifWritesSinceOnly wait if writes were done since this UNIX timestamp
string | bool$wikiWiki identifier accepted by wfGetLB
string | bool$clusterCluster name accepted by LBFactory. Default: false.
int | null$timeoutMax wait time. Default: 1 day (cli), ~10 seconds (web)
Returns
bool Success (able to connect and no timeouts reached)
Deprecated:
since 1.27 Use LBFactory::waitForReplication
