FILTER_VALIDATE_EMAIL not working

[kn0wl3dg3]

Any idea why this wouldn't work? It's straight off the w3c site and isn't echoing anything at all

 

$email = "someone@exa mple.com";
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo "E-mail is not valid<br />";
} else {
echo "E-mail is valid<br />";
}

Works for me.  Is that everything in your script?  Maybe you have something else affecting it.  How are you calling it?

[kn0wl3dg3]

That's it. That's the whole script. I was just trying to get it to work; I had tried it once before and just wrote a regex instead when I got frustrated.

 

Maybe it's in my .ini settings?

It is?  Even without <?php tags?  How are you calling it?

[kn0wl3dg3]

This is the entire thing:

 

<?php
echo 'Learning Email Filter<br />';


$email = "someone@exa mple.com";
echo $email; // to make sure it's being set

if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo "E-mail is not valid<br />";
} else {
echo "E-mail is valid<br />";
}

echo 'This will appear after the filter script if it works<br />';
?>

 

Maybe I'm not calling it correctly since you keep asking how I'm calling it. This was straight off the w3c site, so I wouldn't know if I was doing it wrong

What I meant was are you calling it via terminal or browser?  Hmm, I copied your script exactly and it's working for me in the CLI and browser.  You may have a fatal error, try adding these 2 lines directly under your opening <?php tag:

ini_set ("display_errors", "1");
error_reporting(E_ALL);

 

Other than that there must be some environment setting that is affecting it.

This is what I get with errors on:

 

Fatal error: Call to undefined function filter_var() in /var/www/html/learning/email_filter.php on line 12

 

As to your other question, terminal or browser, I'm not sure what you mean, but i wrote it in a file and opened it in my browswer, so I'm assuming the answer is browser

You need php version 5.2.0 or greater for filter_var functions. Do you have 5.2.0 or higher?

No...phpinfo() says PHP Version 5.1.6

 

That must be the issue. Thanks!

Good to know, didn't even see it when I went to the manual...
