stristr weirdness

[ralph4100]

ok here's the code:
[code]<?php

function checkFor($n)
{
//let's see if this syntax works...
//it's supposed to be true for any variation (regarding capitalization)
//of the word 'reset'
echo 'checking \''.$n.'\'...';
if(stristr('reset',$n)!==false) {
echo 'true';
}
else {
echo 'false';
}
echo '<p>';
}

checkFor('reset');
checkFor('RESET');
checkFor('does not contain ');
checkFor('does contain reset');
checkFor('rEsEt');
checkFor('ReSeT');
checkFor('reeeeset');
?>[/code]

and here's the output

[code]checking 'reset'...true
checking 'RESET'...true
checking 'does not contain '...false
checking 'does contain reset'...false
checking 'rEsEt'...true
checking 'ReSeT'...true
checking 'reeeeset'...false[/code]

stristr() should not return false for 'does contain reset' because 'reset' is in the string 'does contain reset'. get me? what's going on here? running php 5.2 btw...

That's because you've reversed the arguments. Stristr's arguments are "haystack", "needle"  Not "needle", "haystack" as you have it.

sometimes programming makes you feel so dumb.
