CakePHP debug（）不工作，但Debugger :: dump（）很好

本文介绍了CakePHP debug（）不工作，但Debugger :: dump（）很好的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

自从PHP4和Cake 1.3以来，我一直使用 debug（$ data）; 来调试CakePHP中的模型输出。

Ever since PHP4 and Cake 1.3 I have been using debug($data); to debug things such as model output in CakePHP.

但是，从升级到PHP5.4，我注意到 debug（$ data）并不总是工作。例如，今天我做了一个简单的 $ data = $ this-> Model-> find（'all'）; debug（$ data）; 显示为空。没有错误，只是在HTML输出中引用事实，我调用调试和行号，然后没有调试输出。

However, since upgrading to PHP5.4, I have noticed that debug($data) doesn't always seem to work. For example, today I did a straightforward $data = $this->Model->find('all'); and the contents of debug($data); appears to be empty. No error, just a reference in the HTML output to the fact that I called debug and the line number and then no debug output.

但是，如果我运行 Debugger :: dump（$ data）; 对完全相同的find，它工作find和我看到整个输出。

However, if I run Debugger::dump($data); on the exact same find, it works find and I see the entire output.

它似乎只发生在 $ data 有大量的数据（例如，100+记录），但我使用的数据集这个大小之前PHP5.4和那里从不是一个问题，没有错误，inline或在apache / php日志表明有任何内存问题，我有调试设置为3。

It seems to only be happening when $data has a significant amount of data (say, 100+ records), but I worked with datasets this size prior to PHP5.4 and there was never a problem and there are no errors, inline or in the apache/php logs indicating that there are any memory issues and I have debugging set to 3.

有人有什么想法为什么这是？我可以方便地开始使用 Debugger :: dump（$ data）; ，但它只是一个额外的尝试每次，我想知道为什么我

Does anyone have any idea why this is? I can obviosly starting using Debugger::dump($data); easily but it's just a little extra to have to try out each time and I'd like to know why I can't just use deubg(); anymore.

推荐答案

这不能只使用 deubg（）;

This can happen with non-utf8 encoded data in your db records - if the rest of your application is UTF-8 that is. debug() will then just output "nothing". var_dump(), print_r() and other php internal methods should still print the output, though.

您通常可以使用iconv（）等将它们重新编码为utf8。

You can usually re-encode them to utf8 using iconv() etc.
