Bug description: strtotime function reduce performance
Description:
------------
Sorry for my bad english.
PHP v5.1.1 : when using strtotime function intensively
in my script the performance as reduced and the script is generate in
0,250 s ?
With PHP 5.0.5, my script is generate in 0,055 s !
I'm test my script with PHP 5.1.1 without strtotime function -> this page
was generate in 0,050 s !
Reproduce code:
---------------
for ($i=1; $i<=30; $i++) {
$timestamp = strtotime("-". (30-$i) ." day");
}
for ( $i = 0; $i < 30; $i++ ){
$j = 29 - $i;
$time_colone = date("y",strtotime("-$j day")).date("z",strtotime("-$j
day"));
}
