什么是PHP?
[编辑]PHP 目前被广泛的应用,它也是开源软件运动中一个成功的例子。PHP受欢迎是因为其语法类似C、它的速度以及它的简单。 PHP是目前分为两个主要版本: PHP 7和PHP 8。
相信大家也曾经尝试过在网站入使用登入登出的功能。而这类登入的功用,大多数会利用服务器语言来达成,而你也很可能与PHP打交道。 PHP语言由Rasmus Lerdorf发明。当初的他写这个小程式,目的只是希望追踪浏览者的资料。
基本上,PHP使静态的网页动态化。“PHP”是一个递归的缩写,它表示“PHP: Hypertext Preprocessor(PHP:超文本预处理器)”。PHP 对超文本文档进行预处理(即 PHP 在输出被发送到浏览器之前进行处理)。因此,页面可以根据条件,在被用户看到之前做出改变。这可以被用来在页面上写一些东西,创建一个多行的表格,使它的行数正好等于用户访问的次数,或者,将网页与 web 数据库(例如 MySQL)相整合。
在开始服务器处理的奇妙旅程之前,您最好对超文本标记语言作一些基本的了解。PHP 也被用来开发 GUI 应用程序;PHP-GTK 用来构建图形用户界面(Graphical User Interfaces,GUI)。

[编辑]Code Snippets
[编辑]Useful for any beginners to learn code from.
PHP 4 & 5
[编辑]Basic Level
[编辑]echo "the text to print";
- This language construct will echo the text between the quotes. This is not a function but a language construct.echo "$var";
- Notice the double quotation marks. Because double quotation marks are used, this will print the value of the variable. If $var="Bobby", this will output:
Bobby
echo '$var';
- Notice that the quotation marks are now single. This will output the literal keystrokes inside the quotes. The example will output:
$var
$var="Jericho";echo "Joshua fit the battle of $var.";
- Other than substituting the value of a variable for the variable name (and one or two other minor items), double quotes will quote literal keystrokes. So this will output:
Joshua fit the battle of Jericho.
Again, if single quotes were used — 'Joshua fit the battle of $var';
— this would output:
Joshua fit the battle of $var.
echo $var;
- If you only want to print the value of a variable, you don't need quotes at all. If the value of $var is "1214", the code will output:
1214
require "url";
- This language construct will include the page between the quotes. Can NOT be used with dynamic pages, e.g.require("main.php?username=SomeUser");
would not work. This is not a function but a language construct.date("Date/time format");
- Function which returns a date from a Unix Timestamp - where H is the hour, i is the minutes, s is the seconds, d is the day, m is the month and Y is the year in four digits - e.g.date("H:i:s d/m/Y");
would return12:22:01 10/08/2006
on 10th August 2006 at 12:22:01.unlink("filename");
- Function which deletes the file specified in filename.
PHP 4
[编辑]Basic Level
[编辑]<?php
$variable1 = 'beginning';
//This is a comment after a variable being defined
if ($variable1 == 'beginning') {
//If is a test to see if a variable has certain
//value and initiates the wanted sequences if true
echo 'Hello World!';
//The echo displays to the page
}
?>
OOP
[编辑]Include OOP based examples, made by experienced developer
PHP 5 Only
[编辑]Basic Level
[编辑]Basics, working only on PHP 5.
file_put_contents("filename", "Text to save");
- Functions which saves the text specified in Text to save to the file specified in filename. Will overwrite existing file contents unless another parameter FILE_APPEND is added.
E.g. file_put_contents("filename", "Text to save");
will write Text to save to filename, but will overwrite existing text whereas file_put_contents("filename", "Text to save", FILE_APPEND);
will write Text to save to filename, but will not overwrite existing text (instead it appends).
