Constructor & Destructor Documentation

◆ __construct()

ProfilerSectionOnly::__construct ( array $params = [] )

Parameters

array $params

Reimplemented from Profiler.

Definition at line 37 of file ProfilerSectionOnly.php.

Member Function Documentation

◆ close()

ProfilerSectionOnly::close ( )

Close opened profiling sections.

Reimplemented from Profiler.

Definition at line 46 of file ProfilerSectionOnly.php.

◆ getFunctionReport()

ProfilerSectionOnly::getFunctionReport ( )

protected

Get a report of profiled functions sorted by inclusive wall clock time in descending order.

Each line of the report includes this data:

Function name
Number of times function was called
Total wall clock time spent in function in microseconds
Minimum wall clock time spent in function in microseconds
Average wall clock time spent in function in microseconds
Maximum wall clock time spent in function in microseconds
Percentage of total wall clock time spent in function
Total delta of memory usage from start to end of function in bytes

Returns: string

◆ getFunctionStats()

ProfilerSectionOnly::getFunctionStats ( )

Get the aggregated inclusive profiling data for each method.

The percent time for each time is based on the current "total" time used is based on all methods so far. This method can therefore be called several times in between several profiling calls without the delays in usage of the profiler skewing the results. A "-total" entry is always included in the results.

When a call chain involves a method invoked within itself, any entries for the cyclic invocation should be be demarked with "@". This makes filtering them out easier and follows the xhprof style.

Returns

array List of method entries arrays, each having:

name : method name
calls : the number of invoking calls
real : real time elapsed (ms)
real : percent real time
cpu : CPU time elapsed (ms)
cpu : percent CPU time
memory : memory used (bytes)
memory : percent memory used
min_real : min real time in a call (ms)
max_real : max real time in a call (ms)

Since: 1.25

Reimplemented from Profiler.

◆ getOutput()

ProfilerSectionOnly::getOutput ( )

Returns a profiling output to be stored in debug file.

Returns: string

Reimplemented from Profiler.

Definition at line 53 of file ProfilerSectionOnly.php.

References getFunctionReport().

◆ scopedProfileIn()

ProfilerSectionOnly::scopedProfileIn ( $section )

Mark the start of a custom profiling frame (e.g.

DB queries). The frame ends when the result of this method falls out of scope.

Parameters

string $section

Returns: ScopedCallback|null
