奇怪的 var_dump 行为 [英] Weird var_dump behavior
问题描述
我有以下代码行:
var_dump(array());
在一个文件中,它输出:
数组(大小=0)空的
在第二个文件中,它输出:
string '<b>数组</b><i>(大小=0)</i><i><font color='#888a85'>空</font></i>
'(长度=119)
任何想法是什么导致了第二个文件?当我查看第二个文件的渲染标记的来源时,我看到:
string</small><font color='#cc0000'>'<pre class='xdebug-var-dump'dir='ltr'> <b>array</b><i>(size=0)</i> <i><font color='#888a85'>empty</font></i><#10;</pre>'</font><i>(长度=119)</i>
UPDATE 1:视图->第一个文件的来源:
<b>数组</b><i>(大小=0)</i><i><font color='#888a85'>空</font></i>
var_dump()
替换为 Xdebugs 自定义函数,如下所述:
Xdebug 替换了 PHP 的 var_dump() 函数来显示变量.Xdebug 的版本包括不同类型的不同颜色,并限制了数组元素/对象属性的数量、最大深度和字符串长度.还有一些其他函数处理变量显示.

猜猜您不知何故/在您的第二个文件中实现了 xdebug.
I have the following line of code:
var_dump(array());
In one file, it outputs this:
array (size=0)
empty
In the second file, it outputs this:
string '<pre class='xdebug-var-dump' dir='ltr'>
<b>array</b> <i>(size=0)</i>
<i><font color='#888a85'>empty</font></i>
</pre>' (length=119)
Any ideas what's causing this in the second file? When I view the source of the rendered markup of the second file, I see this:
<pre class='xdebug-var-dump' dir='ltr'><small>string</small> <font color='#cc0000'>'<pre class='xdebug-var-dump' dir='ltr'> <b>array</b> <i>(size=0)</i> <i><font color='#888a85'>empty</font></i> </pre>'</font> <i>(length=119)</i>
</pre>
UPDATE 1: the view -> source of the first file:
<pre class='xdebug-var-dump' dir='ltr'>
<b>array</b> <i>(size=0)</i>
<i><font color='#888a85'>empty</font></i>
</pre>
var_dump()
is replaced by Xdebugs custom function, as mentioned here:
Xdebug replaces PHP's var_dump() function for displaying variables. Xdebug's version includes different colors for different types and places limits on the amount of array elements/object properties, maximum depth and string lengths. There are a few other functions dealing with variable display as well.

Guess you're somehow/where implementing xdebug in your second file.
