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"
