<?php$bMan = TRUE; //逻辑型$Name = "SafeDebug"; //字符串$Money = 10.5; //小数$Age = 100; //整数var_dump($bMan);echo ''; //换行var_dump($Name);echo "";var_dump($

$query = 'select * from `userinfo` where `name` = \''.$username.'\';';$query = 'select * from `userinfo` where `name` = '.$username.';';虽然两条语句都正确，都是可以执行的，但是希望大家在写的时候，尽量写成第一条语句，并且，大家可以吧$username这个

<?php//define a array$smilies = array( ':)' => 'smile.png', '=)' => 'smile.png', ':|' => 'neutral.png', '=|' => 'neutral.png', ':(' => 'sad.png', '=(' => 'sad.png', ':D' => 'big_smile.png',

<?php echo 'SERVER_ADDR ' .$_SERVER['SERVER_ADDR']. ''; echo 'HTTP_ACCEPT ' .$_SERVER['HTTP_ACCEPT']. ''; echo 'HTTP_HOST ' .$_SERVER['HTTP_HOST']. ''; $allow_empty_referer = TRUE; if(i

<?php// echo $_SERVER['argc'].'';// echo $_SERVER['argv'].''; if( $_SERVER['QUERY_STRING'] != '' ) { echo 'QUERY_STRING '.$_SERVER['QUERY_STRING']. ''; } echo 'SERVER_ADDR ' .$_SERVE

如果没有PHP环境的可以看这篇文章http://blog.youkuaiyun.com/safedebug/article/details/17137977 好了，我们首先来看一个简单的代码<?php printf("My Name is %s My Age is%d ","SafeDebug",100);?>大家看，是不是很接近C语言？运行结果：My Name is

<?php//我是注释/*我也是注释*/$bMan = TRUE; //逻辑型$Name = "SafeDebug"; //字符串$Money = 10.5; //小数$Age = 100; //整数echo "My Name is $Name ";echo 'My Age is ' . $Age .

PHP也属于一种脚本语言，既然是脚本语言，那么通常变量的声明都会弱一些，我们直接看代码<?php$Name = "SafeDebug";$Age = 100;printf("My Name is %s My Age is %d ",$Name,$Age);?>运行结果：My Name is SafeDebug My Age is 100 通过这个例子，

<?php$ServerName = 'localhost';$UserName = 'root';$PassWord = 'root';$con = mysql_connect($ServerName,$UserName,$PassWord);if(!$con){ die('Could not Connect Server! Error'.mysql_error()
