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

preg_match expects a string input not an array. If you use the method you described you will receive:

Warning: preg_match() expects parameter 2 to be string, array given in LOCATION on line X

You want in_array:

if ( in_array ( $str , $array ) ) {
    echo 'It exists';
} else {
    echo 'Does not exist';
}
