Rip Javascript in PHP with a str_replace()

So yesterday, I gave a nod to David Baker's preg_match across multiple lines. And now, the reason I was looking for something along that route, tada!



function rip_java($content) {
$p = '|(\<script.+?\>.+?\</script\>)|ms';
preg_match_all($p, $content, $matches);
if ($matches[0]) {
foreach ($matches[0] as $v) {
$gp = '|http://drincruz\.blogspot\.com|i';
preg_match($gp, $v, $gpmatches);
if (!$gpmatches) {
$content = str_replace($v, '', $content);
}
}
}
return $content;
}


Javascript is very useful in this revision of the internet. However, if you allow other people's javascript on your site, then well, that's an entire whole different security issue. So what we wanted to do at work was only allow certain javascript to run on our sites; and that javascript being the code that we write.

This was written in PHP because we're using it with WordPress' content_save_pre filter.

Cheers!

I'm working on a plugin that required a multiple-line REGEX match. For whatever reason, my mind went blank even though I've done it before. Anyhow, here's a nice write-up by David Baker.

Exclude Directories in Bash Find | practical web development & design. cincinnati, oh

Just a quick blurb to thank tcmacdonald's blog for the help with this bash find command snippet:

find . -type f -not -path "*svn*" -exec chmod 644 '{}' \;


To be specific, I'm using `find` in a for loop to get all directories but I didn't want the results for the root directory (./).

So my snippet now looks like:

for f in `find . -maxdepth 1 -not -path '.' -type d`; do
...


And now I don't see the results for ./ listed! Thank you! Cheers!
