Extract a Number Between Tags

[Mister_L]

Hi,

I have the following code:

$text="<ListPrice>15</ListPrice>";
preg_match('/<ListPrice>(\d+)<\/ListPrice>/s',$text,$matches);
echo $matches[0];

My goal is to extract the number inside the ListPrice tags in a decimal format,not as a string.The code above outputs 15,however, when I try to convert it to a decimal using the intval command,for some reason I get the value zero.How do I solve this?

Thanks.

<?php 
$text="<ListPrice>15</ListPrice>"; 
preg_match('/<ListPrice>(\d+)<\/ListPrice>/s',$text,$matches); 
if(is_string($matches[1])) { 
 $matches[1]=intval($matches[1]); 
 echo 'Converted to intval();<br>'; 
 echo $matches[1]."<br>"; 
 echo htmlentities($matches[0]); 
} 
else { 
 echo 'Already a Numeric Value<br>'; 
 echo $matches[1]."<br>"; 
 echo htmlentities($matches[0]); 
} 
?> 

EDITED

TheMadScientist already offered a correct solution, but to see why yours wasn't working, try using:

echo htmlspecialchars($matches[0]);

instead.

As explained by the preg_match documentation [us.php.net] (emphasis mine):

$matches[0] will contain the text that matched the full pattern
