sample PHP page I'll start out by explaining some of the things I don't like about PHP. If I get this all out of the way, you can get to the useful stuff. I'll use this opportunity to say something instructive about how to use the language, based on its strengths and weaknesses, though, so it's not wasted time entirely. 1. 2. 3. 4. 5. 6. 7. 8. 9. For a first "assignment" to practice your incipient PHP skills after reading this tutorial, try writing a script that generates a webpage with this text file as the displayed content, formatted so that it is recognizable, readable, and clear on-screen.

Comparer le temps de chargement de deux sites Mardi 7 décembre Web - 7 décembre 2010 :: 07:38 :: Par Camille Je ne pense pas que je vais vous l’apprendre : le temps de chargement des pages fait partie depuis plusieurs mois des critères de pertinence du moteur de recherche de Google. Un nouveau service intitulé Which loads faster vient de voir le jour, il permet de comparer le temps de chargement de deux sites web. Cet Je ne pense pas que je vais vous l’apprendre : le temps de chargement des pages fait partie depuis plusieurs mois des critères de pertinence du moteur de recherche de Google. Cet outil open-source a été développé en HTML et en JavaScript, et le code s’exécute coté client pour éviter d’avoir un temps de réponse coté serveur. Une fonctionnalité permet de comparer en boucle (5, 10, 100 fois…) et de retourner la moyenne du site le plus rapide à charger. Sans oublier les fonctions de partage et d’exportation au format CSV qui seront bien utiles pour vos comparatifs.

Twig - The flexible, fast, and secure template language for PHP PHP command line syntax checking Posted April 24th, 2010 in PHP The PHP CLI (command line interface) allows basic syntax checking of a PHP file. I'll show the basic usage of this in this post and then a couple of ways to check all files in a directory, and all files recursively down the directory tree as posted by a couple of people on Twitter. Syntax checking a single PHP file from the command line The syntax for checking is like this, where the -l flag is a lower case L: If the syntax in the file is correct you will see this: If there are errors then theses will be listed as in the following example output: Note that the syntax checking only checks for syntax errors - it does not report the usage of variables which have not yet been defined, functions or class which have not be declared etc. So something like this will pass: but these will not: Syntax check all PHP files in the current directory

The Ternary Operator | Practical PHP Programming There are three operators that are complicated enough to get their own section, of which the first is the ternary operator. It is called the ternary operator because it takes three operands - a condition, a result for true, and a result for false. If that sounds like an if statement to you, you are right on the money - the ternary operator is a shorthand (albeit very hard to read) way of doing if statements. Here's an example: First there is a condition ($age < 16), then there is a question mark, and then a true result, a colon, and a false result. So, in essence, using the ternary operator allows you to compact five lines of code into one, at the expense of some readability.
