I haven't reopened you previous bug due to the fact that
you dont have a replicateable testcase and my testcase
doesn't reproduce anything close to your result. This
should be tracked in 6608 (which I just posted to).

This issue was opened previously and closed without resolution two and
a half years ago due to lack of feedback in bug #6608. I made a comment
there but I'm not sure if closed topics are seen, so I'm opening it
here. I apologize if I shouldnt have opened a new bug report.
I'm running on OSX with PHP 4.3.0. The performance with a large array
that uses sizeof() in a loop is very poor. It's abut 50X slower than it
should be.
The following takes 8-10 seconds:
for ($i=1;$i<=sizeof($spell);$i++) {
$sentence=str_replace($spell[$i][0],$spell[$i][1],$sentence);
}
Whereas the following takes only .18 seconds:
$end=sizeof($spell);
for ($i=1;$i<=$end;$i++) {
$sentence=str_replace($spell[$i][0],$spell[$i][1],$sentence);
}
Other notes that might help: the array is stored in a file accessed by
require_once(), and the loop is in a function that brings $spell in as
a global variable.
