[SOLVED] Grabbing Info from another page....

[PHPNewbie55]

I am trying to grab some data from another site...

 

I need to grab the data inbetween these tags:

 

<span id="inv_message">CONTENT</span>

 

This is the current inventory of the individual product...

 

The <span id="inv_message"></span> is always the same.. just the content changes.

 

I read this post :: http://www.phpfreaks.com/forums/index.php/topic,172445.0.html

But I couldn't figure out how to just grab the data inbetween the <span id="inv_message">  AND THE </span>

 

Any Advice..??

I am trying something like this:::

 

 

<?php

$data = file_get_contents("http://www.THE_URL.com");
$inventory = preg_match('/<span id=\"inv_message\">.*?<\/span>/',$data);
print "$inventory";

?>

 

But that isn't right... it just returns 1

 

I am missing something.....

preg_match returns a bool integer for success or failure. You need to pass it the variable that you want it to put the matches found into.

<?php

$data = file_get_contents("http://www.THE_URL.com");
preg_match('/<span id=\"inv_message\">.*?<\/span>/',$data, $matches);
print_r($matches);

?>

Cool... that prints:

 

<?php
Array ( [0] => Quantity on Hand: 5 )
?>

 

So how do I get it to just print:

 

Quantity on Hand: 5

 

 

Totally dumb noob here.............. ???

If there is only one match, you can just use the first index of the array, 0, and print it. If there are more, you can loop through the array and print each one.

echo $matches[0];

I got it...

 

<?php
print "$matches[0]";
?>

 

That really helps a lot thank you very much!!!
