I understand this code doesn't actually make sense, it's not finished. But during the trial and erroring process is when I figured out it was crashing. If anything it should execute and give me the wrong results, show an error, or get caught in an infinite loop. Actually, the infinite loop piece might be it.

Is there any way to trap this? Some sort of recursion limitation?

Now that I am looking at the online manual, this page http://www.php.net/functions has the exact same concept.

However, the expected result would be that PHP kills it, at least with a message.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

this is the function again:

<?php
$config['base_dir'] = "/home/foo";

$uri = ereg_replace('^/bootstrap.php', '', $_SERVER['PATH_INFO']).'/';

function uri_check($uri, $level) {
    global $config;    
    $uri = substr($uri, 0, strrpos($uri, '/'));    
    if(file_exists($config['base_dir'].$uri.'.php') ||
file_exists($config['base_dir'].$uri.'/index.php')) {    
echo "something";
    }
     uri_check($uri, $level+1);   
}

uri_check($uri, 1);
?>

it is apparent that the issue is an infinite loop. i need to put the uri_check() call inside of the file_exists() stuff.

the expected result would be a friendlier crash. something about a maximum recursion limit reached (i thought that error already existed?)

>this is the function again:
Thanks, but I asked for COMPLETE reproduce case.

>it is apparent that the issue is an infinite loop.
Then it's apparent that this is stack oveflow.

i am sorry, but what is not complete below?

that script right there is all you need.

i would appreciate this being filed as a feature request for graceful handling of a recursion limit, now that i was able to determine it.
