Delete Everything After a Special Character

I am new to regex, and I think this is my best solution. I am trying to find away to remove all text after a special character is found.

At the moment I am playing with 

preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $word);

But as you probably know, that only removes all special charters, not everything after the first special character is found.

You could find the index of the first occurrence of the special character with preg_match() and then use substr().

If you want to remove every character starting from the first character different from a-zA-Z0-9_ %[].()%&-, you can use the following:

preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-].*/s', '', $word);

If instead, you want to remove every thing after a character from a-zA-Z0-9_ %[].()%&- is found, you can use the following:

preg_replace('/[a-zA-Z0-9_ %\[\]\.\(\)%&-].*/s', '', $word);

You can simply do 

$word = "Overflow's";

preg_match('/[a-zA-Z0-9_]+/', $word, $matches);

print_r($matches);

Which returns:

Array
(
    [0] => Overflow
)

You can turn it around and use preg_match:

preg_match('/^[a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', $word, $matches);

$matches[0] will contain the value you are looking for.
