I can see what u are saying. Its all about the ===
Anyhow.. this thing does not work in a loop. I guess this is my prob. There
might be something wrong with the boolean. I tryed it with different
settings, but still wrong:
Here is what I mean:
$fruit = array('apple','banana','cranberry');
$

No it doesn't. How on ear
If the key is 0, array_search will return 0, it does not
start at 1.
$arr = array('apple','banana','cranberry');
$key = array_search('apple', $arr);
print $key; // 0
If 'apple' was not found, $key would then equal
to boolean false. Be sure to use "=== false"
to check failure because 0
Just looking at the manual here and it explains quite specifically that
array_search() is meant to be used with associative arrays, not indexed
arrays. I think the best way to do what you want is to do is to set up a
loop and test each index against eregi(); If true then you know your index.
