意外的括号' [' -PHP [英] Unexpected bracket '[' - PHP

问题描述

我正在为我的小应用程序团队的Java代码编写一个小型存储库，整个代码中都出现此错误.

$base = explode(".", $class)[0];

仅在此 one 行代码中才会出现此问题.据我所知，以上是正确的PHP语法，这是怎么回事?

解析错误:语法错误， 27/b>行中的 .../mitc/code/index.php 中出现意外的'['/p>

解决方案

这称为数组解引用，并且仅适用在PHP 5.4中 +.无论哪里出现错误，您都可能正在运行PHP 5.3.x.

I'm writing a small repository for my little app team's Java code, and I have this error all over my code.

$base = explode(".", $class)[0];

The problem occurs only with this one line of code, every time. As far as I know, the above is correct PHP syntax, so what's going on?

Parse error: syntax error, unexpected '[' in .../mitc/code/index.php on line 27

If you'd like to see the error, it's at http://chancehenrik.x10.mx/mitc/code/ and elsewhere on my site.

解决方案

That's called array dereferencing and only works in PHP 5.4+. You're probably running PHP 5.3.x wherever you are getting that error.
