Php regex function needs modification

hi I have this function which strips out some characters from teh string. I would like it to exclue the following: ==================================== (double quotes("),single quotes(') semi colon(;) tab space . ==================================== This is the function function cleanname($thename){ $patternCounter=0; $patterns[$patternCounter] = '/[\x21-\x2d]/u'; // remove range of shifted characters on keyboard - !"#$%&'()*+,- $patternCounter++; $patterns[$patternCounter] = '/[\x5b-\x60]/u'; // remove range including brackets - []\^_` $patternCounter++; // $patterns[$patternCounter] = '/[\x7b-\xff$]/u'; // remove all characters above the letter z. This will eliminate some non-English language letters // $patternCounter++; $replacement =""; return preg_replace($patterns, $replacement, $thename); } Thank you
