Unset Joomla! Scripts from Template

unset-scripts.php

// Unset unwanted Scripts - by name
$unset_script = array('k2');

foreach($this->_scripts as $name=>$script)
{
	foreach($unset_script as $script)
	{
		if (strpos($name,$script) !== false)
		{
			unset($this->_scripts[$name]);
		}
	}
}

Try this. Bit cleaner.

// Unset unwanted Scripts - by name
$unset_scripts = array(
	'k2',
	'...',
);

foreach($this->_scripts as $name=>$script)
{
	if (!preg_match('#(' . implode('|', $unset_scripts) . '#i', $name))
	{
		continue;
	}

	unset($this->_scripts[$name]);
}
