[SOLVED] How can I get the value between two slashes?

[papaface]

Hello,

I am trying to get the number inside of this string:

user/worstmovieever/video/1957687/someotherparameter/

I need a way of fetching: 1957687 out of there

 

Anyone have any ideas?

You could do it with a regular expression:

 

<?php
$str = 'user/worstmovieever/video/1957687/someotherparameter/';
preg_match('|[0-9]+|',$str,$matches);
$num = $matches[0];
echo $num;
?>

 

Or if the number is always in the same place in the string, you could explode by the slashes:

 

<?php
$str = 'user/worstmovieever/video/1957687/someotherparameter/';
$bits = explode('/',$str);
$num = $bits[3];
echo $num;
?>

Thanks for that. However I think that only works if those are the only numbers in the string. Its likely since the string is dynamic that there will be more numbers in the string. But these will be the only numbers within two slashes. Also the URL is not always the same length, so I need a way of targetting the numbers between the two slashes.

If the number is definitely the only one contained between two slashes, try:

 

<?php
$str = 'user/worstmovieever/video/1957687/someotherparameter/';
preg_match('|/([0-9]+)/|',$str,$matches);
$num = $matches[1];
echo $num;
?>

Works, thanks
