I have a string like this, read from an html file: ' VALUE="16">' The value could be any number. I am trying to get that number.
If you have that exact string and you want to extract just the number, then a simple regex to delete all non-numeric characters should suffice.
I have this so far, i was hoping someone might tell me how to get that number:
<?php
$handle = fopen("page.php", "r"); while (!feof($handle)) { $buffer .= fgets($handle, 4096); } fclose($handle);
$result = stristr($buffer, 'NAME="c"'); print ("Result:<br />".$result);
?>
Ok, so I don't see ' VALUE="16">' in here anywhere -- I think you need to be a lot more descriptive about the source content and what exactly you want to extract, and provide a few examples, so that we can cover all your bases.
Regular Expressions are _probably_ what you need, but you REALLY need to provide a decent description and multiple examples of what you want, otherwise we're just wasting time.
