How do i search an array in php and return true if it finds one of my variable?

if (array_search($soca, $user_socs))

I know that this will search the array by inputing a variable and an array but i was wondering if it is possible to make it return true, because since it doesn't return true, my if statement is not being carried out.

You need to code this function to expect a return of FALSE if it does not find what you are looking for.

So 

if (array_search($soca, $user_socs) !== false) {
    // then I found something
    // not sure what but its defintely not 
    // returning a failed to find situation
} else {
    // I did not find anything
}

Note the use of the !== and NOT != this is expressly for situations where a function can return actual data that might equate to false but not actually be false i.e. where it may return the 0'th occurance its a valid occurance which may be confused with false if you just us ==.
