mb_strlen()

mb_strpos()

static Fallback::mb_strpos (   $haystack,   $needle,   $offset = 0,   $encoding = ''  )

static

Fallback implementation of mb_strpos, hardcoded to UTF-8.

Parameters

	$haystack	String
	$needle	String
string	$offset	optional start position
string	$encoding	optional encoding; ignored

Returns

int

mb_strrpos()

static Fallback::mb_strrpos (   $haystack,   $needle,   $offset = 0,   $encoding = ''  )

static

Fallback implementation of mb_strrpos, hardcoded to UTF-8.

Parameters

	$haystack	String
	$needle	String
string	$offset	optional start position
string	$encoding	optional encoding; ignored

Returns

int

mb_substr()

static Fallback::mb_substr (   $str,   $start,   $count = 'end'  )

static

Fallback implementation for mb_substr, hardcoded to UTF-8.

Attempts to be at least moderately efficient; best optimized for relatively small offset and count values – about 5x slower than native mb_string in my testing.

Larger offsets are still fairly efficient for Latin text, but can be up to 100x slower than native if the text is heavily multibyte and we have to slog through a few hundred kb.

Parameters

$str
$start
$count	string

Returns

string

Definition at line 66 of file Fallback.php.

mb_substr_split_unicode()

static Fallback::mb_substr_split_unicode (   $str,   $splitPos  )

static

Parameters

$str
$splitPos

Returns

int
