Little help with preg_match

[cataiin]

Hi guys.

I have this "sentence":

"key":"321313-0381","something":"value,"

and I want to obtain only 321313-0381. The problem is somethings differs, isn't always the same.

I've tried:

$start = '"key":"';
$end = '","';
preg_match("/$start(.*)$end/s", $content, $match);
$result = $match[1];
echo "$result";

 But unsuccessful. For $end = '\/'; too. Can I get a little help?

What does it echo right now?

[cataiin]

321313-0381","something":"value,"

That looks like JSON.

$obj = json_decode("{" . the string . "}"); // if you don't have the {}s already
echo $obj->key;

Don't work.

Notice: Trying to get property of non-object in www\index.php on line 10

Probably because the string comes from external URL.

[requinix]

Or it's not JSON. I only guessed that it might be because you didn't post the actual $content string.

No idea about fixing with preg_match? Or anything else... Ty!

Try this...

 

 

preg_match('#"key":"(.*?)"#',$content,$match);
echo $match[1];

[cataiin]

 

Try this...

preg_match('#"key":"(.*?)"#',$content,$match);
echo $match[1];

More than perfect! Thanks!

if you have control over the external file, you should change the format to be JSON, or else serialize the data, so that you can more easily parse it.
