Extract all urls from preg_match_all - php

Question

I'm working on my code to fetch the href urls from the variable $message after when I'm fetching the data from the database. I have got a problem with using preg_match_all to fetch the href tags from the variable because it will display the array in the output like twice.
Here is the output:
Array ( [0] => Array ( [0] => https://example.com/s-6?sub=myuserid [1] => https://example.com/s-6?sub=myuserid
[2] => https://example.com/s-6?sub=myuserid [3] => https://www.example2.com/1340253724 [4] => https://example.com/s-6?sub=myuserid ) )
It should be:
Array ( [0] => https://example.com/s-6?sub=myuserid [1] => https://example.com/s-6?sub=myuserid
[2] => https://example.com/s-6?sub=myuserid [3] => https://www.example2.com/1340253724 [4] => https://example.com/s-6?sub=myuserid ) )
Here is a minimal example:
<?php
$message = 'Click Here!
Watch The Video Here!
HERE
Example2.com/1340253724
Here';
//find the href urls from the variable
$regex = '/https?\:\/\/[^\" ]+/i';
preg_match_all($regex, $message, $matches);
print_r(matches);
?>
I have tried to use a different way like this:
foreach($matches as $url)
{
echo $url;
}
And also I have tried this:
foreach($matches as $url)
{
$urls_array[] = $url;
}
print_r($urls_array);
The results are still the same. I have tried to find the answer on google, but I can't find the answer for a solution.
Unfortunately, I am not be able to find the solution for this, because I have got no idea how I can fetch the href tags using preg_match_all to display the elements and store in the array.
The problem I have found that something have to do with the variable called $matches.
Can you please show me an example how I can use to fetch the href tags using with preg_match_all so I could store be able to store the elements in the array?
Thank you.

Answer 1

As wrote in documentation preg_match_all
$out[0] contains array of strings that matched full pattern, and
$out[ 1] contains array of strings enclosed by tags.
So you could do like following
foreach($matches[0] as $url)
{
echo $url;
}

Answer 2

Try this:
foreach($matches[0] as $url)
{
echo $url;
}

Hi,
as far as I correct understand your problem is that u received one to much nested array with results and you cant read yours URL that are also as array?
One of the solution that u can use is getting rid of unnecessary nested array. You can do this by using PHP Array function array_shift().
From php.net manual
array_shift() shifts the first value of the array off and returns it [...]
So the trick is that returned value will be your array with data through which you can loop.
A bit of sample with your case:
//from the moment when you use preg_match_all and have matches
preg_match_all($regex, $message, $matches);
$urls = array_shift($matches);
foreach($urls as $url) {
//do something with URL
}
Of course you can different use array_shift(), thats just a simple sample ;)
Cheers!
