The problem is where the value of input form become like this:

PHP Code:


		
			
<p>
    <img alt="" height="312" src="http://localhost/house/images/images/home-office-3-582x312.jpg" width="582" /></p>

What PHP can do to clean that text input so I get only

PHP Code:


		
			
http://localhost/house/images/images/home-office-3-582x312.jpg

to save on database

Thanks for help

Lets take what we know about the string to see what we can do. We know:
1. It always will start with http://
2. It always ends with "

So basically what you need to do find the occurrence of every http:// and find the quote directly after it then take the contents between those positions. I haven't tested this, but something like the following should work

PHP Code:


		
			
<?
$off=0;
$start="http://";
$end = "\"";

while(1)
{
    //If a link is found in the text
    if(stripos($haystack,$start,$off) !== false)
    {
        //Set the temporary start and end positions
        $startPos=stripos($haystack,$start,$off);
        $endPos=stripos($haystack,$end,$location);
        
        //Grab the current link
        $link=substr($haystack,$startPos,$endPos-$startPos)
        
        //Do what you want to the link here such as add it to an array
        
        //Set the offset to the end so it can search for the next link
        $off=$endPos;
    }
    else
    {
        break;
    }
}
?>

Alternatively, if your code is always going to be well formed XHTML use an XML parser such as simpleXML.
