Include() & Require() Files - What Should I Do ?	View Content

Php Folks,

As you know, typing the same code over and over again on all files is daunting.

I was wondering, if I can have an error_reporting.php file and then put:

include('error_reporting.php');

at the top of all my php files as header, where the error_reporting.php would have this content:

	<?php
	error_reporting(E_ALL);
ini_set('error_reporting','E_ALL');
ini_set('display_errors','1');
ini_set('display_startup_errors','1');
?>

Q1. Is that ok or not ?

Q2.

Usually, I have a conn.php with content like this:

	<?php
	$conn = mysqli_connect("localhost","root","","db_database");
$db_server = 'localhost';
$db_user = 'root';
$db_password = '';
$db_database = 'test';
$conn->set_charset('utf8mb4');//Always use Charset.
	if (!$conn)
{
    //Error Message to show user in technical/development mode to see errors.
    die("Database Error : " . mysqli_error($conn));
    
    //Error Message to show User in Layman's mode to see errors.
    die("Database error.");
    exit();
}
	?>

And then, on all my php files, I just reference to the conn.php by putting the following line on the header:

	include('conn.php');

Or:

	require('conn.php');

And on each php file, just before dealing with mysql, I have a line like this:

	mysqli_report(MYSQLI_REPORT_ALL|MYSQLI_REPORT_STRICT);
$conn->set_charset("utf8mb4");

Now, I am wondering, why should I write the above 2 lines on all my php files that deal with mysql ? To keep things short, why don;t I just add those 2 lines in the error_reporting.php ? So, it looks like this:

error_reporting.php

	<?php
ini_set('error_reporting','E_ALL');//error_reporting(E_ALL);
ini_set('display_errors','1');
ini_set('display_startup_errors','1');
	mysqli_report(MYSQLI_REPORT_ALL|MYSQLI_REPORT_STRICT);
$conn->set_charset("utf8mb4");
?>

Shall I do this or not ?

Include() Vs. Require()

Why would I want to use include() vs. require() ??

(It seems like most people use "include()", but I would think "require()" would be better/safer...)

Hello.

Include is identical to require, only require stops any further script execution.

Just wondering if anyone could give me a good example, where 'require' should be used instead 'include'.

Thanks.

Include/require Problem

Similar Tutorials

View Content

Hello,

I have a small and annoying problem. Imagine that I have a main folder on my FTP server which has index.php and I then have a php folder for all of my small scripts and an includes folder for misc files. So, for instance

http://www.somedomain.com/index.php
http://www.somedomain.com/php/somescript.php
http://www.somedomain.com/includes/somefile.html

Inside somescript.php, I need to use one of the files from the includes folder, like this for example:

require('../includes/somefile.html');

This is all fine, but the problem is when I include the PHP file on my index.php page. Then I am telling PHP to go one step back to find the includes folder, but the problem is that it only needs to go one step back if it PHP script is not included on some page outside of the php folder. If I run php/somescript.php, there is no problem, but if I include php/somescript.php on my index.php, then there is trouble!

I hope you guys understand what I mean.

Thanks in advance!

PS - I would appreciate if the solution is not about moving php/somescript.php or using full URLs in my includes.

Hello all, i just joined today, because am going nuts with php and the include or require statement/function

I want to use them to link to a header. Nothing hard about that , I would say. But my bit of code below just does not work.

I am running them in a test area on my server. Just to be safe The file L2.php is in the same directory/folder ( showing my age).

I should say that am have been programming a while but only using php for about 4 weeks and this normal simple bit of code has me stumped.

I am building the site in visual studio and atom.

any pointer would be received with joy

The content of L" is also below .

<?php include_once('L2.php'); ?>

centents of l2.php below

Does Require/include Cache The Document?

Similar Tutorials

View Content

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"); ?>

Include/require Vs Creating Your Own Custom Function

Similar Tutorials

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?

Important!! Is My Logic Sound?? A Question About Include, And Require

Similar Tutorials

View Content

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??

.

Can You Use Get With Include Files

Similar Tutorials

View Content

Can you include a file and append info to be grabbed by using GET? For example, can you have an include file like this...

Code: [Select]
include('file.php?id=1');

And then in the file "file.php" I would use $_GET['id'] to do other things in the code.

I tried it and it's not working. I'm getting this error... "Warning: include(file.php?id=1) [function.include]: failed to open stream: No such file or directory in..."

Just want to find out if this should be doable before I continue testing why it's not working for me.

If it should work, should I be using something other than include maybe? (like require or require_once?)

Include Files Class Scope

Similar Tutorials

Using PHP Version 5.2.13
My question: How do I access a class and it's methods from an included file?

I have an Index.php page that calls two methods:
<?php get_header(); ?>
<?php get_footer(); ?>

and it creates a class in an include file
<?php include_once($_SERVER['DOCUMENT_ROOT'].'/includes/common.html');?>
$site = new WebSite($site_name); // Creates a bunch of properties, defines some methods, etc...
$site->initialize();

<?php get_header(); ?> ends up including a another file (header.php)
<?php get_header(); ?> ends up including a another file (footer.php)

All calls in Index.php to methods in my class work. ie <?php $site->display_section('column'); ?>
But calls in either the header.php or footer.php to methods in my class fail with "Call to a member function is not an object".
I understand what the error means but I don't understand why. I thought all functions and classes defined in an include file have global scope. As per PHP.NET's documentation:

"When a file is included, the code it contains inherits the variable scope of the line on which the include occurs. Any variables available at that line in the calling file will be available within the called file, from that point forward. However, all functions and classes defined in the included file have the global scope."

The include that creates the class is something that I have inherited from another developer and I actually can't change the scope. I've tried with global $site = new WebSite($site_name);. It actually breaks the entire site.

How can I access classes, properties, methods in an include file?

Any help would be appreciated. I've been racking my head for several days now on it and it's probably some newbie thing that I am completely overlooking. I hope I've provided enough background and info.

Thanks,

Brian

Protecting Class/include Files

I been wondering how to protect all the files that contain classes, functions and forms in php to prevent direct access to something that the user shouldnt be able to without the proper check's (typing http://server/inc/login.php insteand of http://server/), and i came to this small idea of checking if an object is set or not but i m wondering if this is really the best idea here's what i have (the case bellow will protect an login form to be accessed directly):

Code: [Select]
<?php
    if(!isset($mysqlobj)) die();
    if( isset( $_POST['username'] ) && isset( $_POST['password'] ) ){
        $login = authentication::login( $_POST['username'], $_POST['password'] );
        if( $login == true ){
            header( 'location:?go=home' );
        }else{
            $_SESSION['message'] = 'loginfailed';
            header( 'location:?go=login' );
        }
    }else{
      if( !empty($_SESSION['logged'] ) && $_SESSION['logged'] == true ){
          header( 'location:?go=home' );
      }else{
          ?>
