如果你magento網站剛從php5.6升到7.0后，或許你會遇到這樣一個錯誤，這是php7給你的見面禮。
发生这种情况是因为在PHP 7你需要說明你将要调用$callback变量作为一个方法（函数）。所以，代码的原始行如下所示（文件app/code/core/Mage/Core/Model/Layout.php）：
|
1 |
<span class="pln">$out </span><span class="pun">.=</span><span class="pln"> $this</span><span class="pun">-></span><span class="pln">getBlock</span><span class="pun">(</span><span class="pln">$callback</span><span class="pun">[</span><span class="lit">0</span><span class="pun">])-></span><span class="pln">$callback</span><span class="pun">[</span><span class="lit">1</span><span class="pun">]();</span> |
为了使它在最新的PHP版本上工作，我们需要用这个代码替换这段代码：
|
1 |
<span class="pln">$out </span><span class="pun">.=</span><span class="pln"> $this</span><span class="pun">-></span><span class="pln">getBlock</span><span class="pun">(</span><span class="pln">$callback</span><span class="pun">[</span><span class="lit">0</span><span class="pun">])->{</span><span class="pln">$callback</span><span class="pun">[</span><span class="lit">1</span><span class="pun">]}();</span> |
