searching string

[techlover]

Hi,

Just wanted to get opinions on the most effective way to do this.

1. I have a string, let's call it $mystring
2. I have an array, let's call it $myarray
3. In $myarray I have thinks like:
   $myarray[0] = "@"
   $myarray[1] = "-"
   and so on.

I simply want to scan $mystring to see if anything in $myarray is in $mystring and if so, let me know.

Thanks
😃

Hi,

The following should do what you need.

<?
	$mystring = "[e-mail]";

$myarray[0] = "@";
$myarray[1] = "-";
$myarray[2] = "\.";

preg_match_all ("/(" . implode('|', $myarray) . ")/", $mystring, $matches);

echo "<pre>";
print_r($matches);
?>

The array $matches will contain the characters that have been matched in the original string. Note that if you need to use what PCRE will consider a "special character" you should escape it in your array. That is why there is a slash infront of the fullstop, it's actually only matching the fullstop (period).

I'm sure there are other ways to do this - but it works for me and it's all neat on one line of commands 🙂

Cheers,
