What is the fastest way to compare a string to every value in an array?

I guess my topic about says it all. I imagine it would be something like preg_match in foreach but I'm not really sure if that would be the quickest way to do it with id#s.

If you wanted to compare the given value against every value in the array you could just use a loop

for ( $loop=0; $loop<count($array_vals); $loop++ )
{
if ( stristr($array_vals[$loop], $match_val) )
{
echo "Found match at position ".$loop."<BR>\n";
}
}

I never was a fan of foreach. But each to there own.

If you just want to find the location of the value in the array and it is a big array you could use a binary chop method to locate the entry.

in_array(), array_search() etc. Think they're quick enough.

You know those two slipped my mind.... forget what I posted earlier.
