意外的括号 '[' - PHP [英] Unexpected bracket '[' - PHP
问题描述
我正在为我的小应用团队的 Java 代码编写一个小型存储库,但我的代码中到处都是这个错误.
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];
问题只出现在这一行代码中,每次.据我所知,以上是正确的 PHP 语法,这是怎么回事?
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?
解析错误:语法错误,在 .../mitc/code/index.php 中出现意外的["27
Parse error: syntax error, unexpected '[' in .../mitc/code/index.php on line 27
如果您想查看错误,请访问 http://chancehenrik.x10.mx/mitc/code/ 和我网站上的其他地方.
If you'd like to see the error, it's at http://chancehenrik.x10.mx/mitc/code/ and elsewhere on my site.
推荐答案
这就是所谓的数组解引用,才有效在 PHP 5.4+ 中.您可能在遇到该错误的任何地方都在运行 PHP 5.3.x.
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.
