Retaining all tags, and removing all txt

Anon

I've ran into a problem.

lets say:

$string = "I <m_34c> love cars <m_76> a lot"

How can I edit the $string (the simplest way posible) so I can only end up with:

$string = "<m_34c><m_76>";

The <m... code can be "<m[0-9]{1,3}[a-z]{0,2}" -- if you know what I mean...

Examples: <m_5> <m_45> <m_9d> <m_23df> ...

That is, I need to strip all the text of $string and retain all the context that is <m_...>

Any help would be appreciated.

Ive searched, read manual to no help...

Best regards,
Omid Sadeghpour

This may not be the most simple fix....sorry in a hurry because of lunch....but basically.

You can can split the string up using the Explode function.

$newstring = explode($string, "");

You will now have a nice array containing all of your individual elements.

Do a test on each array variable testing that the first character of the array is '<' or that the array contains '<' in it and put those pieces into either another array or two seperate variables. Then Glue them together.

Once suggestion.

Here we go... this works. Suggestions, PHP should add a "OPOSITE" function. Incase you replace all the "<>" in a string the OPOPSITE should remove all the other characters and leave the selected ones in the string...

For future users, the code below works nice if you have an array with values coded in < >.

$cars = "I <m_2> love 5 cars <m_24> in <m_14> my <m_12> small life";


$cars_array = explode("<m_", $cars);

$i = 1;
while ($i < count($cars_array) )
	{


		$end_tag = strpos($cars_array[$i], ">");
		$cars_array[$i] = substr($cars_array[$i], 0, $end_tag);

		// Replacing values
		$cars = ereg_replace('<m_'.$cars_array[$i].'>', $admin_log_messages['m_'.$cars_array[$i]], $cars);
		$i++;

	};

echo $cars;
