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

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. |
