On top of this, every time a ' is entered it gets preceded by \. If I just
check for the characters like below that doesn't happen. Totally confused.
if(preg_match("/^[-A-Za-z0-9_.' ]+$/", $string)) {
You don't need to escape the apostrophe if the pattern isn't quoted
with apostrophes in PHP or delimited by apostrophes in the PREG
pattern. But generally there's no harm in escaping characters
unnecessarily; it just makes for messier code.
Here is a simple test of the regexp I recommended yesterday using the pattern:
"/^[A-Za-z0-9!@#$%&()*;:_.'\/\\\\ ]+$/"

If you're still having trouble getting this to work, please post a
link to a page that demonstrates it not working and give us the
complete PHP statements so we can find your error.
As an additional resource, here's Oliver Steele's RegExp workbench:
