PHP里的中文变量说明
PHP的一个有效的变量名由字母或者下划线开头,后面跟上任意数量的字母,数字,或者下划线。按照正常的正则表达式,它将被表述为:'[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*'。
注: 在此所说的字母是 a-z,A-Z,以及 ASCII 字符从 127 到 255(0x7f-0xff)。
复制代码 代码如下:
$var = 'Bob';
$Var = 'Joe';
echo "$var, $Var"; // 输出 "Bob, Joe"
$4site = 'not yet'; // 非法变更名;以数字开头
$_4site = 'not yet'; // 合法变量名;以下划线开头
$i站点is = 'mansikka'; // 合法变量名;可以用中文
?>
刚别人给我了个php文件,打开一看我惊了,难道传说中的用中文编程就这么容易被PHP实现了
刚才翻了一下中文php手册,确实有中文变量实例
