hi all,
how can I check for a blank space in this pattern ?

$pattern = "/\band\b|\bor\b|[\'\#\=\+\"\%\$\!\,\]]/i";

A problem with no solution is a problem viewed from the wrong angle

It's fairly easy, since you are using a character class:

$pattern = "/\band\b|\bor\b|[ '#=+\"%$!,\]]/i";

Inside the char class definition the space itself is sufficient. ALso, there is no need to escape meta characters inside a char class definition unless they would interfere with the syntax of the whole expression. Therefore, just the right square bracket and the double wuote need escaping.
