[RESOLVED] help with str_replace

[ukreandy]

I have a site with embedded code for videos. They are from all different sites with different width and height. I want to use str_replace to set all the width and height to the same.
Here is what I have and is not working.

$code = "<embed src=blah blah blah blah width="(any number)" height="(any number)"></embed>";
$vidsize = array("width=\"*\"", "height=\"*\"");
$newvidsize = array("width=\"425\"", "height=\"350\"");
$newcode = str_replace($vidsize, $newvidsize, $code);
echo $newcode;

The problem I have is the * symbol used for the $vidsize. I know that is the multiplication sign, but I am wanting it to find any set dimension and replace with the 425x350.

Thanks

Looking at your initial $code variable, it is not correct.
- You are using double quotes nested in double quotes.. the inner double quotes must be escaped. So I used single quotes with inner double quotes.
- Your src does not encapsulate anything in quotes.

I made changes to your $code line, plugged in some numbers, then came up with this solution.

Would this work?

$code = '<embed src="blah blah blah blah" width="123" height="123"></embed>';
$newvidsize = array('width="425"', 'height="350"'); 
$codeUpdated = preg_replace('#(width="\d+" height="\d+")#', "$newvidsize[0] $newvidsize[1]", $code);
echo $codeUpdated;

Ouput (viewable via right-click and viewing source):

<embed src="blah blah blah blah" width="425" height="350"></embed>

If you didn't want to go the regex route:

$code = '<embed src="blah blah blah blah" width="123" height="123"></embed>';
$newvidsize = array('425', '350');
$array = explode('"', $code);
for($i = 0, $x = 0, $total = count($array); $i < $total; $i++){
	$array[$i] = (ctype_digit($array[$i]))? $newvidsize[$x++]: $array[$i];
}
$codeUpdated = implode('"', $array);
echo $codeUpdated;

Ouput:

<embed src="blah blah blah blah" width="425" height="350"></embed>

Thanks! That is what I was looking for. I used the preg_replace option.

Perfect. Please don't forget to flag this thread as resolved (select 'Mark Thread Resolved' from Thread Tools menu at the top).
