PHP Programming Tips

Looping statements, like Do-While looping statements, While looping statements, and For looping statements, makes programming very easy, even at making PHPs. But did you know that there is something that looping statements can’t loop? That’s right! There is something. Looping statements can’t loop If-Else statements. That’s because when the looping statement starts, it goes through the If-Else statement, and then, whatever the statement the If-Else statement supplies, it will be the new statement the looping statement loops, and the If-Else statement will be left aside. I’ve been creating PHPs in our school and I tell you, it’s very frustrating that your looping statements are not looping the whole statements you put inside it. Thus, your website will not work properly. The only solution that I find is that you have to use Switch statements. Switch statements are like If-Else statements, but the Switch statements are more specific. Try it! It works, even at other programming language

4. Zend Optimizer – is a closed source solution which is purely a code optimizer with no code caching feature. This makes Zend Optimizer different from other PHP accelerators. Also, Zend Optimizer is very useful in running some types of protected scripts. However, one major setback is that the time taken to optimize scripts may exceed the performance gains, hence, resulting to an overall slowdown.

5. Zend Platform – originally Zend Cache and then Zend Accelerator, this commercial product was, at first, sold for $995.00 and $1495.00 US dollars per server. In 2006, this pricing was removed from Zend.com.

6. ionCube PHP Accelerator (PHPA)– is claimed to be the first freely available PHP performance solution to rival the peformance of the commercial Zend Cache product. It was launched in 2001 and was intended to maximize the performance potential of PHP. However, PHPA is now discontinued, although there is an announcement regarding the development of a more advanced replacement.

7. Turck MMCache – though discontinued, Turck MMCache is still widely used today.

A PHP accelerator is an extension created to improve the performance of software applications written using the PHP programming language. Here is a list of PHP accelerators:

1. Alternative PHP Cache – a free and open framework used for caching and optimizing PHP intermediate code. The latest stable version is 3.0.18. It works with all PHP versions including PHP5.2.

2. eAccelerator – Originally part of the Turck MMCache project, eAccelerator used to have a PHP encoder and loader but was removed after December 2006. Its latest stable version is 0.9.5.3 and it supports PHP4 and all PHP5 releases including 5.2.

3. Xcache – is a powerful and stable PHP opcode cacher which can run on production servers under high load. It has been also tested on linux and supports ThreadSafe/Windows. Its latest stable version is 1.2.2 and supports PHP_5_1 PHP_5_2 HEAD (6.x)
