RE: [PHP] regex for cleaning up username

[Dave]

Am partially successfull after taking a further look into things.  the following
(while ugnly) correctly catches everything except the \ character for some
reason.  ideas?

if(preg_match(/['.' ,!@#$%\^*()+=\/\\:;?|]/',$MyString)){
# echo error, character found
}

Try searching for anything that's not a word character:
if(preg_match(/\W/,$mystring))
that should return true if it matches anything except for a letter,
number, or _...

Will likely switch to that syntax for brevity sake.

your regex didn't work because you didn't use /'s at the beginning and
end of your regex...

caught this one after further review of the regex documentation

Try four backslashes instead of two:

preg_match(/['.' ,!@#$%\^*()+=\/:;?|]/',$MyString)
