Checking both file_exists and then doing fopen seems a bit silly.
Trap the error from fopen, and just use that as your file_exists test.
I suspect http://php.net/file_get_contents will be SLIGHTLY faster
than doing all of this code, though:
if (filemtime($filename) > time()) $contents =
@file_get_contents($filename);
if ($contents === false){
//error-handling code
}
else{
echo $contents;
}
Then, of course, we have to wonder if you NEED $contents for later use
in the script.
If not, something like this will clock in better:
$bytes = @readfile($filename);
if ($bytes === false){
//error-handling code
}
This seems to be the best solution. I do not need $content anymore. I ll
post results. :)
The difference here is that you don't even stuff the file into the PHP
string. It's all read and passed out to stdout in low-level internal
PHP C code, and the data never needs to hit "PHP" variables which are
"more expensive" to setup and maintain.
Note that which is REALLY fastest will probably depend on the size of
the files, your OS system cache, your hardware, and maybe which
version of PHP you are using, if the underlying functions changed.
Must be nice to be worried about 0.0x milliseconds -- I'm fighting a
mystery 3.0 seconds in a data feed for a search engine myself :-)
Search engine ... thats the most complicated!

[PHP] a couple of problems with PHP form
I am trying to set up some validation for my php form with the email
field using the following code:
if(!eregi("^(.+)@(.+)\\.(.+)$",$_POST['email']))
{
$error_msg .= "Your email appears to be invalid.";
$ok = "false";
}
I am trying to accomplish not being able to enter anything other than
a valid email string
this doesn'r seem to be doing anything.
also, I want the field to appear hilighted when there is no
information so I am doing this:
"
and I have an error class set up in my CSS, such as
.error {border: 1px solid red;}
this is not doinf anything either.

Re: [PHP] Funky array question
one more thing... if you have php <5 and >= 3.0.6, you could use
stristr for case insensitive comparison without having to deal with
the slower and more cumbersome regex.

Re: [PHP] Funky array question
Hello,
what have you been trying for comparison so far that has not been
working?
if you have php 5, you would want to use stripos, which is case-
INsensitive, not strpos, which is the opposite.
Also, note the warning on the man page. you would want to use a
triple equals sign "!===false" because stripos could return a zero or
an empty string which is actually "==false".
http://www.php.net/stripos/
if you do not have php 5, i would use regex so you can get case
insensitivity.

[PHP] Re: [PHP-WIN] Is this a PHP bug?
It's because PHP is trying to convert different var types into a common var type and then compare them when you use ==. === means compare value AND type so that's why it fails. Your string, 'Some kind of string' is getting converted down to the lowest common denominator, an int. Since there are no numbers in the string to grab onto, it gets converted to nothing, an int value of zero. If you had $x = "0" or if $y had contained numbers at all, it wouldn't have passed. But this is why when you use $x.'' it works properly because now you have "0", it's been converted to a string value "0". Good catch on that though, shows good methodical debugging :) So in the future, either use === or be extra aware of your variable types and make sure you're comparing properly. Good luck! -TG = = = Original message = = = $x = 0; // Numeric zero $y = 'Some kind of string'; if ($x == $y) echo 'they equal using =='; if ($x === $y) echo 'they equal using ==='; The above will echo 'they equal using =='. The values don't look very equal to me. Can anyone explain the logic behind this? I'm heading home now but look forward to your explanations tomorrow. PS Incidently, to 'fix' it so it behaves as it should, you can code: if ($x.'' == $y.'') echo 'this will not print and all is good.'; Regards ..

[PHP] QF & FB duplicate element form
Hi guys!
I'm getting crazy about the following error working with QuickForm +
FrontBuilder for a sign up form.
As usual, login / passwd are shown in form by FB:
[..]
$auth = DB_DataObject::factory('auth');
$fb_auth =& DB_DataObject_FormBuilder::create($auth);
$frm_auth =& $fb_auth->getForm();
$auth->postGenerateForm(&$frm_auth,&$fb_auth);
[]
I need user retypes password, then I added postGenerateForm() function
within Auth class. I also added preProcessForm() for encrypt passwd and
it works.
[.]
function postGenerateForm(&$form,&$fb) {
// FALLA!! Repite dos veces el campo
$form->addElement('password', 'passwordR', 'Retype password',
array('size'=>32, 'maxlenght'=>32));
$form->addRule('passwordR', 'Retype password', 'required');
$form->addRule(array('password', 'passwordR'), 'Password does not
match.', 'compare');
}
function preProcessForm(&$data) {
if(isset($data['password'])) {
if($data['password'] != $this->password) {
$data['password'] = md5($data['password']);
}
}
//igualar id_user(auth) e id_user(users)
}
[]
I think this should be work fine but text element passwordR is shown
three times instead two. If postGenerateForm() is not called then only
one password element is shown. Does anybody know why?
Thanks

That code should work, and the example on your site seems to work for
me. The only thing you should make sure is that $url is an absolute URL,
even if you're redirecting within your own site (e.g. you shouldn't use
../lyrics/ or /lyrics/) - you may be able to get away without doing this
but it's not the "correct" way to do things.
You may want to change your code to this:
header("Location: $url"); // no point in concatenating since double

exit();
I can't remember why, but calling the exit(); function fixed a problem I
was having a while back when I was being sent to the right URL but the
