Hey there i just managed something that i never accomplished beforei
kill a httpd process from PHP,
i run the following code
<?
$slen=strlen($enc);
for ($i=0;$i<$slen;$i=$i+2) {
$swap=$enc[$i];
$enc[$i]=$enc[$i+1];
$enc[$i+1]=$swap;
}
?>
$enc is a string and has an even length
This silly lines of code make the apache child process crash, if i
change it to
<?
$slen=strlen($enc);
for ($i=0;$i<$slen;$i=$i+2) {
$swap=$enc[$i];
$swap2=$enc[$i+1];
$enc[$i]=$swap2;
$enc[$i+1]=$swap;
}
?>
it works well.
what the hell is happening here?
i run php 4.04pl1 as apache module under linux.
