Regular Exp Help

[tobeyt23]

I am trying to check my youtube code value and see if &rel=0 has been added to it and if not added it. I suck at regular exp can someone help?

Well, unless you want to provide more specifics such as examples of the input data and the location of where the parameter will go I don't think you need regular expression.

 

if(strpos($value, '&rel=0')===false)
{
    $value .= '&rel=0';
}

sorry basically im taking the you tube embed code which someone else is adding to our db. So i want to change the height and with which i am doing with:

 

$vid            = '<object width="640" height="385"><param name="movie" value="http://www.youtube.com/v/zMQ6LfyA-0o?fs=1&hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/zMQ6LfyA-0o?fs=1&hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="385"></embed></object>';
$search         = array('<embed', '></embed>');
$replace        = array('<param name="wmode" value="transparent" /><embed', ' wmode="transparent"></embed>');
$find           = array('/height(=)(".*?")/', '/width(=)(".*?")/');
$replacement    = array('height="175"', 'width="200"');

$vid = str_replace($search, $replace, $vid);
$vid = preg_replace($find, $replacement, $vid);

 

I also need to then see if the rel=0 is added to the value="" and add it if not
