I would not want to do this, because it will slow down the execution of the scripts on average, since in_array() will have to traverse the entire array to produce the count you want, instead of just stopping at the first match.

Try using count(array_keys($array, "foo")) - this will return the number of times "foo" occurs in $array.

I'd like to see in_array returning the number of values matching, instead of just true/false.

IMHO, it would not create any backwards compatibility problems, since 0 equals false anyway and > 0 equals true.

It would make constructing dual-parameter descisions much easier.

For example - a bounce script, where "bounce_count / day" > 6 AND "bounces /week" = 5.

This is very hard to do now, but with in_array returning the number of hits, it takes out at least 2 loops and a seperate "counts" array.
