Question

I have the next code:

$string = "hello to all world";
$strings_compare = tomorrow, hello, world;
$string_arrays =split(',',$strings_compare);

      for ($i=0; $i<count($string_arrays); $i++){
          $resultado = preg_match("/$string_arrays[$i]/",$string);
             if($resultado == false){   
             echo "no match";              
             }else {
            echo "match";
             }
      }

in this code the results are:
no match, match, no match

and the results should be: no match, match and match. What is my error?

if I change the $string by $string='say hello to all world now'
the results are match, match, match, this is OK.

It works fine for me when I’m using valid array syntax.

<?php
$string = "hello to all world";
$string_arrays = array("tomorrow", "hello", "world");

for ($i=0; $i<count($string_arrays); $i++) {
    $resultado = preg_match("/$string_arrays[$i]/",$string);
    if(!$resultado) {   
        echo "no match";              
    } else {
        echo "match";
    }
}

Returns

no matchmatchmatch
