searching arrays

[morrisoner]

anyone know how to search an array for a value and return the element number (same as key i think) ????

Theres in_array() function, which finds occurences, but I havent used it.

Heres a little snippet which you can use to search through array:

while (list ($key, $val) = each ($test)) {
	if (strstr($val,$searchstring))
	{
    echo "$searchstring found in key: $key";
	}
}

Why don't you use the foreach control structure by using

foreach($test as $key=>$val) {

if (strstr($val,$searchstring))
{
echo "$searchstring found in key: $key";
}
 }

in_array is much nicer than iterating through the whole array manually.
