Simple PHP Replace All Occurences with Something Else (stristr isn's suitable)

Hello.

Let's say I have a block of text in $content.

How do I replace all occurrences of:

"http://megavideo.com/?v=[random alphanumeric string here, 8 chars long]"

PHP:

with something like:

"http://megavideo.com/v/[the same random variable taken after the = sign above]"

PHP:

...while keeping everything else intact (the rest of the text)?

 

Something like this ?

str_replace('?v=', 'v/', $string);

PHP:

 

str_replace or preg_replace would work. For the preg replace use

$string = preg_replace('/\?v=/i', 'v/', $string);

PHP:

 

No, no. You got it wrong. What I really want to do is replace all plain Megavideo URLs like:

http://www.megavideo.com/?d=AROTWUTX

Code (markup):

to the embed code like:

<object width="450" height="330">
<param name="movie" value="http://wwwstatic.megavideo.com/mv_player.swf?image=&v=4Q7V1T88"></param>
<param name="allowFullScreen" value="true"></param>
<embed src="http://wwwstatic.megavideo.com/mv_player.swf?image=&v=4Q7V1T88" type="application/x-shockwave-flash" allowfullscreen="true" width="450" height="330"></embed>
</object>

Code (markup):

 

Well why show that example to begin with. It has nothing to do with what you want it doing other than it's a mega video link you need to use a regex to capture the video id and output the video html then I guess using regex

 

Yes, that's what I'm trying to do but I don't know how. The thing is that if I use preg match replacement it will just replace the part after "=" instead of the whole URL which looks like http://megavideo.com/?v=DSAKDSKD

As for the example, that was the first video that got in my hands so I gave it as an example. What's wrong with that?

 

The first result example you gave was completely different from the one you really wanted, that's what was wrong with it.

I get the feeling you're still not telling us everything. If you want something that works, you have to give complete examples of input and output.

 

Ok, here's a complete example. The quote below is assigned to a variable called $string.

After doing some matching and replacing I want to receive the content below inside $string:

I just love watching videos at Megavideo.

Here's one of my favorites:
<object width="450" height="330"><param name="movie" value="http://wwwstatic.megavideo.com/mv_player.swf?v=1UGLO8JZ"></param><param name="allowFullScreen" value="true"></param><embed src="http://wwwstatic.megavideo.com/mv_player.swf?v=1UGLO8JZ" type="application/x-shockwave-flash" allowfullscreen="true" width="450" height="330"></embed></object>

Also, yesterday I watched another wonderful video there but it doesn't work today:
<object width="450" height="330"><param name="movie" value="http://wwwstatic.megavideo.com/mv_player.swf?v=7K3VWSSY"></param><param name="allowFullScreen" value="true"></param><embed src="http://wwwstatic.megavideo.com/mv_player.swf?v=7K3VWSSY" type="application/x-shockwave-flash" allowfullscreen="true" width="450" height="330"></embed></object>

Hi,try yourself using http build url (check also parse url )

 

Untested, but try:

<?php

$string = <<<EOF
