Do you get a crash or a parse error?

I get a crash, my whole system stops and I have to restart usually.

I get a crash, my whole system stops and I have to restart usually.

Can you post the whole source of a script that crashes on the web somewhere? (Or if it's small, put it into this bug report). Can you also tell which version of PHP4 you are using?

I use PHP4.0.5dev on NT4.0
the code is simple 
<table border=0>
<?
for ($i = 0; $i = $newvalue; $i++)
 {
?>
<tr>
<td>
<? echo $i; ?>
</td>
</tr>
<?
}
?>
</table>

Two things.

1) You should use "$i == 10" for a comparison. By using a single equals, you're assigning 10 to $i, which is always "true".

2) What do you expect it to do?  If you want to loop to iterate 10 times, you should use "$i<10" (the loop continues while the second term is TRUE)
