I need some help with adding a PHP Code into my Website. I need to get a code to add in someones IP Address.

Example: From IP: (IP Address Here)

I also need to get a code to add how long it took to load the page at the bottom of each page.

Any help with this and I would be extremly grateful, thanx heaps.

I assume that you are running the page through the php parser already? Either by using a ".php" file extension or by modifications to the .htaccess file as required.

The method required to post the page generation time (not the load time) is to include a section of php code at the top of the page which creates a start time and another section of code at the bottom which creates a stop time. To find the page generation time is simply a matter of subtracting one from the other and echoing it to the html page. Here is some code for that:

CODE

<?php $time_start = microtime (true); ?> // place early on the page
:
:
<?php // place this code late in the page
$time_end = microtime (true);
$load_time = $time_end - $time_start;
echo "Page Generated in $load_time seconds";
?>

This code works as is for php5 only. If your server is running php 4, there is a function available on the php site that will work for the earlier versions. Search their site ( www.php.com ? ) for the microtime() function and it is explained in the first example box.

To display the User'$s IP address, you reference the Global values found in the "$_SERVER" array. The complete list of information that is available in the Array can be found by printing the contents of the array using the following code:

CODE

<?php
print_r($_SERVER);

But of course, you only want one element of the array, so rather than displaying all the data, use the following bit of code on the page where you want the IP address displayed:

CODE

<?php
echo "Your IP Address is $_SERVER[REMOTE_ADDR]";
?>

Hope this helps.

Yes it does help. The IP Address works fine.

However the page generation time is way too long ... it is now coming out looking like this:

Page Generated in 0.00013999999999997 seconds

Is there anyway to shorten to this say:

Page Generated in 0.00013 seconds

Thanx in advance

$load_time is the variable that stores the timing, which in your case is "0.00013999999999997". You can always treat that variable as a string and trim unwanted characters.

I recommend the following code, using substring.

CODE

$load_time = substr($load_time, 0, 6)

You can also look into this page for information and usage of the substr() function.
www.php.net/substr

You code will eventually be:

CODE

<?php // place this code late in the page
$time_end = microtime (true);
$load_time = $time_end - $time_start;
$load_time = substr($load_time, 0, 6)
echo "Page Generated in $load_time seconds";
?>

Thanks for the assistance there Inspiron. I'm sure Jesse will be thankful.

Major problem with that one. My main page cannot be viewed at all with that code. I get a complete blank (white) website with nothing on it at all :|

My apologies...

I've forgotten to close that code with a ";" character.

CODE

$load_time = substr($load_time, 0, 6);

Add a ";" at the end of this line.
It should work now..

Haha thanks. Actually you answered her question. I'm just giving the support for shortening the length of the output timing text.
That's where my sig comes into it's use.. "Inspiron, At Your Service"..

Well, I didn't catch that either when I looked at it. Glad it all worked out. That's a problem when trying to solve these sorts of difficulties without the code. Sometimes it just blows up in your face. If you would've had the code available, you would be able to test it beforehand.

Jesse, (and others),

Here is the php code for php versions earlier than php5. I found it in a Tutorial written by Albus D, so I am quoting it here instead of using code tags.

QUOTE

<?php

$starttime = explode(' ', microtime());
$starttime = $starttime[1] + $starttime[0];

?>

<?php

$mtime = explode(' ', microtime());
$totaltime = $mtime[0] + $mtime[1] - $starttime;
printf('Page loaded in %.3f seconds.', $totaltime);

?>

And the reason it failed when you tried it is because the "printf()" function formats the output. The "%.3f" defines the format as floating point decimal using 3 digits and was not displaying the number correctly because your page generation times were too fast (small). Had it been formatted as "%.6f", it would have worked better for you.

Awesome, thanx its working fine now

And the only problem was the ";" missing
