This code example is useful when you want to take an input string and break (split) it into search terms where each work is a search term and several words in "" are a single string to search by.

<?php
$String
='this is a "test expression" for search input';
preg_match_all('/"[^"]+"|[^"\s,]+/', $String, $Tokens); 
?>



Usage Example
<?php
$String
='this is a "test expression" for search input';
preg_match_all('/"[^"]+"|[^"\s,]+/', $String, $Tokens); 
Echo
"<PRE>";
var_dump($Tokens);
Echo
"</PRE>";
?>

will print:
array(1) {
  [0]=>
  array(7) {
    [0]=>
    string(4) "this"
    [1]=>
    string(2) "is"
    [2]=>
    string(1) "a"
    [3]=>
    string(17) ""test expression""
    [4]=>
    string(3) "for"
    [5]=>
    string(6) "search"
    [6]=>
    string(5) "input"
  }
}
