Regular Expression. How to match?

[lopes_andre]

Hi,

 

I have been searching for regular expressions documentation but after 2h I don't have a clue how to match this...

 

<a href="announce.asp?REF=570637">

 

Ok, I need to match the number after REF= and before ">

 

It is possible to define a patter to match this?

 

Best Regards,

Andre.

Do you want to match just that number, or a possible six number comination? Also are you matching the whole thing (including html tag) or just the sent data.

 

$pattern = "/^[0-9]{6}$/";
$data = $_GET['REF'];
if(preg_match($pattern,$data)) echo "Match";
else echo "Not match";

 

This should work if you're getting the 6 figures number and want to match any combination of six figure number.

Hi,

 

Thanks for your reply.

 

I don't have explain well, sorry. I need to match the numbers between and add those number to an array. The number does not have 6 figure, could have 3, 4, 5, 6, 7 or more.

 

This is possible?

 

 

Best Regards,

André.

Ok, this should do what you want

 

$pattern = "/^[0-9]+$/";
//$data = $_GET['REF'];
if(preg_match($pattern,$data)){
echo "Match";
$your_array[] = $data;
echo $your_array[0];
}else echo "Not match";

 

The pattern will match only numbers. If it is a number it gets added to an array

Hi,

 

Thanks again for your reply.

 

I have tested but is not matching anything with the regular expression. I have debuged the script, but I'am confused. Why I have 2 results for this pattern?

 

Here is an image of the debuger:

preg_match("/REF=(\d+)\"/",$string,$matches);
echo $matches[1];

One more question,

 

This concatenation syntax is right?

 

function('http://www.example.com/delete_a.asp?ID= . $matches[1]','','','off');

function('http://www.example.com/delete_a.asp?ID=' . $matches[1],'','','off');

[lopes_andre]

Thanks again.

 

Best Regards.

function('http://www.example.com/delete_a.asp?ID=' . $matches[1],'','','off');

 

Not that it is any different in result, another option would be:

function("http://www.example.com/delete_a.asp?ID=$matches[1]",'','','off');
