这种差异是 PHP 特有的,并不 适用于其他语言, 所以请不要修改你的 C 或 Java 代码并指望它们能立即变快, 没用的。 ++$i 更快是因为它只需要 3 条指令(opcodes),$i++则需要 4 条指令。后置递增实际上会产生一 个临时变量,这个临时变量随后被递增。而前置递增直接在原值上递增。这是最优化处理的 一种,...
Note: It's fine if you are playing around with PHP codes with the help of an online PHP editor, to enjoy a full-fledged PHP environment (since online editors have several caveats, e.g. embedding PHP within HTML) up and running on your own machine is much better of an option to ...
PHP 将随文件信息数组一起返回一个对应的错误代码。该代码可以在文件上传时生成的文件数组中的error字段中被找到,也就是$_FILES['userfile']['error']。 此错误代码的值是UPLOAD_ERR_*常量中的一个。 down 241 Viktor¶ 10 years ago Update to Adams old comment. This is probably useful to someone. <...

++$i更快是因为它只需要3条指令(opcodes),$i++则需要4条指令。后置递增实际上会产生一个临时变量,这个临时变量随后被递增。而前置递增直接在原值上递增。这是最优化处理的一种,正如Zend的PHP优化器所作的那样。牢记这个优化处理不失为一个好主意,因为并不是所有的指令优化器都会做同样的优化处理,并且存在大量没...
