[Solution] user agent stylesheet override site stylesheet on Chrome but not Firefox

My problem was this: i wanted to put bold on text which was in select's option by putting style - wont-weight. I had succeed only on Firefox. Because chrome user agent stylesheet were overriding my stylesheet.
I tried to solve the problem for hours. Finally with my friend's help i found the website - electrictoolbox. And it says that only firefox allows to do that... that means we cant use wont-weight on chrome for option, select and optgroup.

My solution was for the bold text changing wont-weight style into color, with dark color for normal text and lighter color for bold required. Also i needed disabling option of bold, so i just added " disabled='disabled' ". That is all..

My result:


a
b


Good luck.

PHP string replace all except numbers and chars

Here is PHP function(code) to remove all but not characters and numbers.

PHP multidimensional array check

Today i faced with problem that array had array inside it. It means that the array is multidimensional. So i was forced to recheck the array check with function is_array to new check. Here is the code of check:

function is_multi($a) {
    $rv = array_filter($a,'is_array');
    if(count($rv)>0) return true;
    return false;
}
