Test and analysis of the speed of extracting core function from PHP data acquisition

Test and analysis of the speed of extracting core function from PHP data acquisition
As a result of the program needs, the PHP acquisition of character extraction in the core of the implementation of the speed test.
Three of the most common extraction methods were tested:
Method One:
<?php
Require "class.debug.php";
function GetContent ($SOURCESTR)
{
$content = Strstr ($sourceStr, ' form ');
$content = substr ($content, 0, Strrpos ($content, ' say ') + strlen (' speech '));
return $content;
}
$SOURCESTR = ' Deny any person any form of speech in this forum which is inconsistent with the laws of the People's Republic of China ';
$debug = new Debug;
$debug->starttimer ();
for ($i = 0; $i < 1000000; $i + +)
{
$RETURNSTR = GetContent ($SOURCESTR);
}
$timeInfo = $debug->endtimer ();
Echo $timeInfo;
?>
Extracted by comparing the low-level character manipulation functions.
Method Two:
<?php
Require "class.debug.php";
function GetContent ($SOURCESTR)
{
$pattern = "/shape (. *?) Words/is ";
Preg_match_all ($pattern, $SOURCESTR, $result);
return $result [1][0];
}
$SOURCESTR = ' Deny any person any form of speech in this forum which is inconsistent with the laws of the People's Republic of China ';
$debug = new Debug;
$debug->starttimer ();
for ($i = 0; $i < 1000000; $i + +)
{
$RETURNSTR = GetContent ($SOURCESTR);
}
$timeInfo = $debug->endtimer ();
Echo $timeInfo;
?>
Use a simple regular to extract.
Method Three:
<?php
Require "class.debug.php";
function GetContent ($SOURCESTR)
{
$content = explode (' shape ', $sourceStr);
$content = Explode (' speech ', $content [1]);
return $content [0];
}
$SOURCESTR = ' Deny any person any form of speech in this forum which is inconsistent with the laws of the People's Republic of China ';
$debug = new Debug;
$debug->starttimer ();
for ($i = 0; $i < 1000000; $i + +)
{
$RETURNSTR = GetContent ($SOURCESTR);
}
$timeInfo = $debug->endtimer ();
Echo $timeInfo;
?>
Extracted by two times explode splitting string.
Before the test my opinion is: 1 > 2 > 3
