PHP - Having A Night Mare With Include Or Require

is there a way to do an include or require to a whole directory? I have only done includes and requires with single files in the past, but have a situation where this could save me a lot of time.

I am using php require to input a page of code.  I am including (require) that file several times within the page.  I am guessing that it executes the file every time, and does not save any page loading time, and in fact probably slowing it down because it has to make the request every time.   Just wanted an expert to confirm or deny my educated guess.  Would it be the same if it were including an html file instead of a php file?

<?php require ("$base_path/main_page_rotation/content4.php"); ?>

I need to include a pagination file in multiple pages or create a custom function but not sure which one to use.

For example:

Code: [Select]
<?php

function test() {
    echo "Hello PHP Freaks!";
}

?>
Or I can create a separate file that echos this statement and include it.

When do you use include/require and when do you create your own custom function?

Hello,
Is this a sound explanation of require and include..
Lets say i have "X" application with an index.php file. in a folder on my domain like so: www.xxx.com/Application X folder/index.php.

// the index.php calls to multiple files with-in the "Application X folder" and database.

What if i move the index.php to another location all together like so:
http://www.xxx.com/notXsubfolder1/notXsubfolder2/notXsubfolder3/index.php //the X application index file..

and then edit the require and include links in the index.php file to paths like this (just example might not be accurate):

require_once '../../../../application X Folder/include/required_file.php';

My question:??
What i want to know is: if the required_file.php has includes of its own, will it take the includes that it requires from its original folder where the Required_file.php is located? or will its paths change the the new index.php location??

.

trying to use a require but not working properly

Fatal error: require() [function.require]: Failed opening required 'get_extra.php?id=1' (include_path='.')

first thing set on page is.. page is profile.php?id=1
$userid = $_GET['id'];

code is:require "get_extra.php?id=$userid";

what can i do to fix this?

thanks

Hi Everyone,

In redesigning my new web site, with the skills I am learning in PHP  I struck upon a thought which I would like to ask:

Is it possible to switch my heading banner from a daytime scene to a night time scene using the time of the local server. Basically I have two links in my database to two separate SWF files. Is there a script available anywhere that would do this?

Thanks!

 I have questions but I also have some good info to share about putting your software in the cloud.  

The situation:

Some of you may have read about the nightmare stories. A developer had a infinite loop in his code that ran all night. This code did things inefficiently that devoured CPU in each iteration. This developer, greatly skilled,  opened his email the next morning and saw a email bill from his cloud provider totaling for $75K. True story. 

Most cloud providers let you define CPU usage thresholds that, when breached, send you a warning but these thresholds, if I understand them, are per account. 

It would seem the claim that cloud resources are available in whatever amounts you need, CPU, disk space, enough RAM to never have to wait on a page faults, etc... the claim that the cloud provides you with infinitely elastic  resources in an "all you can eat for one price" contract smells just a like a little like 💩

I did cloud development for many years with ServiceNow starting when it was a help desk and I watched it evolve into one of the best cloud development platforms out there. At one customer site I installed and managed it it out of the cloud and saw its insides and I can tell you its core code is not so terribly efficient. IMHO the cloud DOES take away 90% of a developer's worries about app performance..

If you call ServiceNow tech support and your problem is diagnosed as a performance issue with your code the first thing they will ask you is "did you follow the developer best practices"? They will politely say "sorry. Here's a link to them implying "fix your code". 

Questions: 

PHP Functions that devour CPU and where there is a better way?

What PHP functions or code techniques waste CPU? I am using similar_text and it does the job but it is slow. Better way?

What is the best way to measure CPU used by a PHP script or by a particular code module, defined as a set of related functions that fulfill a common purpose or by a single line of code? The purpose being to identify inefficient modules of code and improve them and even if the code is damn near perfect then at least can know what code modules are the most expensive.

CPU killin users (and developers too), how can they be identified?

I need to store data on cumulative CPU usage for any of the above and compare it with the free amount they give you and warn CPU hogs before they breach a threshold and generate $75K bills that were not in the plan.

Any info you have on avoiding surprise $75K CPU bills from a cloud provider are welcome

I've messed around with this for three hours now, and it's driving me batty.  I'm running the following Query:

mysql_select_db("myDB", $con);
$query = "UPDATE mytable SET Name = '$Name', Address = '$Address', City = '$City', State = '$State', Zip = '$Zip', Phone = '$Phone', Website = '$Website', Type = '$Type' WHERE id = '$ID'";

The problem is that it's not updating my database.  I've tried everything.  I've forced the page to Echo out the variables so that I know they're right.  I've run (successful) Delete queries to make sure I'm connecting to the right table.  I've forced it to spit out the variables at the end of the Update.   Everything I've tried works beautifully... except the Update itself.  It doesn't error out or anything- it acts like it's Updating, but the data never changes.  I can add to the database and delete from it, but it refuses to let me Update anything. 

I've looked all over the net, and tried every variation I can find.  Nothing works.   I also tried this:

$query = "UPDATE `testbed` SET `Name`=[$Name],`Address`=[$Address],`City`=[$City],`State`=[$State],`Zip`=[$Zip],`Type`=[$Type],`Phone`=[&Phone],`website`=[$Website] WHERE `ID`=[$ID]";
 
And

$result = mysql_query("UPDATE mytable SET Name = '$Name', Address = '$Address', City = '$City', State = '$State', Zip = '$Zip', Phone = '$Phone', Website = '$Website', Type = '$Type' WHERE id = '$ID'");

None of them do anything at all.

Is there a better way to define the page name other than   require("./anyfolder/any.php"); 
trouble is i define the page by using ./myfole/anyfile.php but if  the page is called from deeper inside my site it dose not work. i have to change all the includes and put an additional . so it ends up looking like this ../myfole/anyfile.php
 

Okay I have 3 files in the following format:

home/run.php
home/config.php
game/check.php

In run.php, I have config.php required as 'home/config.php' and then in config.php I define an absolute path.

However, I'm trying to require run.php from check.php but I keep getting an issue because then config.php isn't included.

I've tried require using 'home/run.php', '../home/run.php' and even an absolute path. What do I need to do?

Hey all, I've been having an issue with require_once from another sub-directory. Origionally I had all my php files in the same spot but I wanted to make a library to clean things up a bit.

Atm I am trying to access my /subFolder/frame_work/sql/dbconnect.rem.php with require once from /subFolder/frame_work/account_data/accountHandler.rem.php. I have looked around a little bit and i know requires\includes looks in relative directorys. So one obvious solution would be to include the entire path name. "var/www/subFolder/frame_work/sql/dbconnect.rem.php".

My problem is I will be accessing this from multiple directories and on localhost the root directory is var opposed to my server which is public_html. I like to edit my stuff in localhost before going public with it and it is going to be a real pain if I have to keep switching var to public_html in every file before I upload. Is there any other solutions I could approach? Any responses would be much appreciated. Thank you for your time.

Hi, i have a DB login system and i was wondering if there was a code that i could put on all of my web-pages so that only members (people who actually logged in) could view tem and the rest would be re-directed to /login/loginfailed.php

If this is not possible, could there be a way to only allow people who came from a specific url to see the page to see them and the rest be re-directed to /login/loginfailed.php

Thanks in advance!

I've just downloaded a 3d party app and I'm finding that most (98%) of the [files].php have a "<?php" but not a "?>" in them.  I created a tst.php...HW and it seems to not care.  An improvement? Mox-Nix? Poor form? Or the same coder the loves 0xEEE text on a 0xFFF background because it's sooooo cool.   Head @ 42 deg /////   Thanks cal    

This is a two part question... my previous post was surrounding an issue with Sessions, now I was told that it may be a server side issue so I contacted my host provider who said to me that sessions cookies REQUIRE https?? now this can't be valid because I've had no issues with sessions prior to this week - second part of this is, is there something I'm missing with maybe an updated versions? 

 

PS: yes, i'm new and simply trying to learn...

This error is very bizarre since I can't seem to debug it. When I require my header, it is included. When I require my footer, it is not. I am 100% the paths are correct, and I tried another file to make sure it wasn't the footer causing the error. Here's the code for the header, footer, and index. If you need to see anything else just tell me.
