Extract Text URL from String

Hello,

I am trying to extract a text link from a given string however I am finding it rather difficult and I am getting no matches for some reason.

My code is:

<?php
  $string = "some random text http://tinyurl.com/dmugyw";
function do_reg($text, $regex)
{
   preg_match_all($regex, $text, $result, PREG_PATTERN_ORDER);
   return $result = $result[0];
}

do_reg($string, '\b(https?|ftp|file)://[-A-Z0-9+&@#/%?=~_|!:,.;]*[-A-Z0-9+&@#/%=~_|]');
?>

Code (markup):

Can anyone explain why I am not getting a match?
I'm wanting to extract the actual text link into a variable so I can use it elsewhere in my script.

Also can someone help me with this.

I have a piece of text "#papa_face win http://www.somelink.com" or "#papa_face http://www.somelink.com"

How can I extract each individual part of the text? If "win" is present in the text I want to run a particular function, but if its not present I want to run another. Is this possible? I don't want it to be to strict so this would also be acceptable "#papa_face win http://www.somelink.com" For this reason I cannot just explode() the string.

Any help would be appreciated

 

For the first matter:
To get started, err on the side for simplicity. Use a simple, easier-to-read-and-debug regex for URL, and consider the slight-less efficient

ereg()

Code (markup):

function instead.

For the second matter:
Use the PHP

explode()

Code (markup):

function to break up the string, using the space character as delimiter. Then you can easily use array_has_key to find "win" if it exists.

 

For the first problem, try using another regular expression. Here is a list of tons of them:

For the second, you can do this:

$string = str_replace("\n",' ',$string);
if(!strstr($string,' win ')){ echo 'win not found';}else{echo 'win found';}

PHP:

Make sure that the newline character is indeed \n.

Peace,

 

I've tried http://regexlib.com/Search.aspx?k=url but I can't get any of them to work
And good idea about the second bit, I'm gonna try it

 

<?php
$string = "some random text http://tinyurl.com/dmugyw";
preg_match('/(http:\/\/)(.*)/', $string, $link);
if (empty($link[0])) {
	echo "Nothing found!";
} else {
	echo $link[0];
}
?>

PHP:

 

Hi,

try :

$str = '<a href="http://foobar.com"> | Hello world Im a http://google.fr | Did you mean:http://google.fr/index.php?id=1&b=6#2310';
$pattern = '`.*?((http|ftp)://[\w#$&+,\/:;=?@.-]+)[^\w#$&+,\/:;=?@.-]*?`i';
if (preg_match_all($pattern,$str,$matches)) {
print_r($matches[1]);}
