Usually, this may seem pretty easy - I tied out some suggested solutions for this topic, but none of them seem to work - I seem to be missing something here...
I'm trying to look if $Address['Address'] contains in its value a character. Let's say 'x'
(preg_match('/'.implode('|',$Address['Address']).'/', 'x', $matches))
or
if (strpos($Address['Address'], 'x') !== FALSE)
Doesn't seem to work the way I called it.
