Hi
is there a command that i can use that can check there isnt a certain item in a string for example "}" if there is it will return something so i can generate an error message and hopefully pull it out and display it
for checking a single character, you can use something like,
if (stripos($string, '}')) { echo "no dice"; }
using preg_match() would be a better option if you're verifying text (ie; ensuring no non-alphabetical/numeric characters)
