PHP - Dynamic Include Files And Security/performance
Hi All,
I have written the following to validate my dynamic includes, one question is i will be using sessions to control user access to certain pages. Obviously the session_start() has to go into my index.php file. Can anyone see any problems with this or my dynamic include validation code. My page varilable is populated using the mod_rewirte function in appache. <?PHP include('inc/settings.inc.php'); if(isset($_GET['page'])) { //remove slashes $page = stripslashes($_GET['page']); //rebuild the extension and file name $filename = 'lib/'.$page.'.php'; //Check to see if the file exists in lib if (file_exists($filename)) { //Dynamic Switch $allowed = array( array("test", "New Customers"), array("home", "Home Page"), ); $iffed = false; $get_section = $_GET['page']; //Create a dynamic switch to check for files being in my allowed array foreach($allowed as $rd) { if($get_section == $rd[0]) { $iffed = $rd; $content = $filename; foreach($rd as $value) { $page_title = $value; } } } if($iffed === false) { //File is not in my include list. die( "Page does not pass the validated inclusion list." ); } } else { //Page does not exist in my lib folder. die('Page does not exist, please contact the administrator.'); } } else { // If no page is requested then default home. $filename = 'lib/home.php'; $content = '1'; $page_title = 'Home'; } ?> Thanks in advance. Sam Similar TutorialsHi I have a function that strips out lines from files. I'm handling with large files(more than 100Mb). I have the PHP Memory with 256MB but the function that handles with the strip out of lines blows up with a 100MB CSV File. What the function must do is this: Originally I have the CSV like: Code: [Select] Copyright (c) 2007 MaxMind LLC. All Rights Reserved. locId,country,region,city,postalCode,latitude,longitude,metroCode,areaCode 1,"O1","","","",0.0000,0.0000,, 2,"AP","","","",35.0000,105.0000,, 3,"EU","","","",47.0000,8.0000,, 4,"AD","","","",42.5000,1.5000,, 5,"AE","","","",24.0000,54.0000,, 6,"AF","","","",33.0000,65.0000,, 7,"AG","","","",17.0500,-61.8000,, 8,"AI","","","",18.2500,-63.1667,, 9,"AL","","","",41.0000,20.0000,, When I pass the CSV file to this function I got: Code: [Select] locId,country,region,city,postalCode,latitude,longitude,metroCode,areaCode 1,"O1","","","",0.0000,0.0000,, 2,"AP","","","",35.0000,105.0000,, 3,"EU","","","",47.0000,8.0000,, 4,"AD","","","",42.5000,1.5000,, 5,"AE","","","",24.0000,54.0000,, 6,"AF","","","",33.0000,65.0000,, 7,"AG","","","",17.0500,-61.8000,, 8,"AI","","","",18.2500,-63.1667,, 9,"AL","","","",41.0000,20.0000,, It only strips out the first line, nothing more. The problem is the performance of this function with large files, it blows up the memory. The function is: public function deleteLine($line_no, $csvFileName) { // this function strips a specific line from a file // if a line is stripped, functions returns True else false // // e.g. // deleteLine(-1, xyz.csv); // strip last line // deleteLine(1, xyz.csv); // strip first line // Assigna o nome do ficheiro $filename = $csvFileName; $strip_return=FALSE; $data=file($filename); $pipe=fopen($filename,'w'); $size=count($data); if($line_no==-1) $skip=$size-1; else $skip=$line_no-1; for($line=0;$line<$size;$line++) if($line!=$skip) fputs($pipe,$data[$line]); else $strip_return=TRUE; return $strip_return; } It is possible to refactor this function to not blow up with the 256MB PHP Memory? Give me some clues. Best Regards, 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?) Hi! I would appreciate your help... How can i include files with get and post data in order to avoid sql injections? The including data has utf8 encoding... Any suggestions???

How can i expire the cookie in include files. I've just gotten back into re learning web development, I have created a contact form however my server is forcing me to use SMTP which will require me to have a config include with my details inside. How do I ensure nobody can open the files in the browser? I have heard of putting the files outside of the webroot or using htaccess files however the passive aggressive answers I got from stack over flow didn't tell me HOW to implement them. The files are Form.HTML Bin/config.php Bin/mail.php Any help is appreciated. 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); $conn->set_charset("utf8mb4"); ?>
Using PHP Version 5.2.13 My question: How do I access a class and it's methods from an included file? I have an Index.php page that calls two methods: <?php get_header(); ?> <?php get_footer(); ?> and it creates a class in an include file <?php include_once($_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 How do you include files from a higher up directory? I'm currently working on a file in public_html/Directory/otherdirectory and want to include a config file that's in public_html/Directory so how would I include public_html/Directory/config.php in the public_html_Directory/otherdirectory/index.php file? I've tried using ../ and ../Directory/ in the includes line but got errors both times Edited April 11, 2020 by Nematode128I 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{ ?> <div id="loginform"> <form action="?go=login" method="post"> <table align="center"> <tr> <td><font size="2">Username</font></td> <td><input type="text" name="username" /></td> </tr> <tr> <td><font size="2">Password</font></td> <td><input type="password" name="password" /></td> </tr> <tr> <td colspan="2" align="center"><input type="submit" value="Login" /></td> </tr> </table> </form> </div> <?php } } ?> Just looking for an "best practice" i tried google for it but i couldnt get to an straight awnser any enlightment is appreciated. I need some help with this. I created an index.php page and I inserted an include statement that referred to a header.html page.

I'm a little confused with the use of absolute paths in PHP. I've always used relative paths but it's becoming an issue with some of the apps I'm working with and absolute would solve the problem. The thing is, I'm getting different results in different places and I'm a little confused. With regular HTML I seem to be able to use / as the root of my site. So if I do the following... Code: [Select] <img src="/images/name.jpg" /> That works fine no matter what page it's called from in the site and no matter what directory that page is in. I need to be able to do that same thing with PHP. Now, in my custom 404 page I have the following... Code: [Select] if($AddressURL == 'http://www.domain.com/blog/files/filename.zip') { header('HTTP/1.1 301 Moved Permanently'); header('Location: /download/filename.zip'); exit(); } That actually works just fine. If I go to the /blog/files/filename.zip (which doesn't exist) in a web browser it winds up downloading the file at www.domain.com/download/filename.zip as expected. Now where I get confused is that include files don't seem to work like that with PHP. If I do this... Code: [Select] require_once('/includes/config.php'); That winds up looking for an /includes folder all the way back at the local server root, not just the web root. so it's looking for /var/includes instead of /var/www/includes and of course that doesn't end up working. So, how come the include file paths work differently than regular HTML paths or header redirects in PHP? Is there any simple way I can always refer to the SITE root no matter what server it's running from? I've tried playing with $_SERVER['DOCUMENT_ROOT'] but it only seems to return the root of the current document, not the root of the whole site. So if I use it within a php file located in /var/www/includes/test.php it considers /includes the root which is not what I want. Any information would be greatly appreciated. Thanks!

I have the following simple code to test against collision on a primary key I am creating: Code: [Select] $machine_ids = array(); for($i = 0; $i < 100000; $i++) { //Generate machine id returns a 15 character alphanumeric string $mid = Functions::generate_machine_id(); if(in_array($mid, $machine_ids)) { die("Collision!"); } else { $machine_ids[] = $mid; } } die("Success!"); Any idea why this is taking minutes to run? Anyway to speed it up? |
