ah thanks wildteen88. problem solved.

hello, I have an associative array that looks like this: Array ( [1940s] => Array ( [tag_id] => 8 [count] => 1 [fontsize] => 16px ) [academic] => Array ( [tag_id] => 13 [count] => 1 [fontsize] => 16px ) ... } I need to be able to change the $array[val]['fontsize'] in a loop. I don't think I'm doing it right, because when I print_r after the loop the fontsize values are not changed. However, the loop echos the desired strings. foreach($tagArray as $array => $val){ $zscoreInt = round($val['count']-$stdev); $$val['fontsize'] = $avgFontsize + $zscoreInt . 'px'; echo $$val['fontsize'] . '<br />'; } What's wrong? Thanks.

i have a php script that searches a mysql database using terms from a user input box.  i want to have a script that will extract "words" (or alphanumeric groupings) from the string and put them into an array. i don't want to create the array based on a string separated by spaces (' ') because that is not secure. what's the best way to do this? thanks
