PHP get page title function

PHP's get_meta_tags function can extract meta-description, meta-keywords etc but cannot find title of the page. Therefore I use following function to catch title of a remote url or a local xhtml file.

function get_page_title($url){

	if( !($data = file_get_contents($url)) ) return false;

	if( preg_match("#(.+)<\/title>#iU", $data, $t))  {
		return trim($t[1]);
	} else {
		return false;
	}
}

Search only in .php files under linux

Sometimes we need to search in only .php, .inc, .txt or template files for a string. Search can take very long time if there are thausend of files or GB-sized files(logs, xml/csv data etc). We can ignore all other files with a find-grep combination and save performance.

find /home/USERNAME -name *.php -exec grep -l 'MYSTRING' {} \;

Drupal problem with inline style <p style=""> and <br />

If your users can not add inline style attributes to your allowed html tags, just create a new role like superuser etc and let this role use full-html. Do not give access to untrusted to use this role. Add <br> to allowed tags and use <br> instead of <br />.

CuteFTP or FTP Client lists just 1998 / 2000 files

If your ftp-software does not display more than 1998 file names (2000 with symbolic links), you must change config file of Pure-FTP and restart ftpd. Use a ssh-client , recommend Putty.

[ssh] pico -w /etc/pure-ftpd.conf

# 'ls' recursion limits. The first argument is the maximum number of

Change this to something like LimitRecursion 20000 20 etc.
