How to find a string in an array in PHP?

Question

I have an array:

$array = array(\"apple\", \"banana\", \"cap\", \"dog\", etc..) up to 80 values.

and a string variable:

$st         


        

Answer 1

If you have more than one value you could either test every value separatly:

if (in_array($str1, $array) && in_array($str2, $array) && in_array($str3, $array) /* … */) {
    // every string is element of the array
    // replace AND operator (`&&`) by OR operator (`||`) to check
    // if at least one of the strings is element of the array
}

Or you could do an intersection of both the strings and the array:

$strings = array($str1, $str2, $str3, /* … */);
if (count(array_intersect($strings, $array)) == count($strings)) {
    // every string is element of the array
    // remove "== count($strings)" to check if at least one of the strings is element
    // of the array
}
