PHP var_export function example explanation

The var_export() function returns structural information about the variable passed to the function. It is similar to var_dump(), except that the representation returned is legal PHP code. var_export must return legal PHP code. In other words, the code returned by var_export can be directly assigned to a variable as PHP code. And this variable will get the same type of value as var_export.

The example in this article describes the usage of the var_export function of the PHP format output file. Share it with everyone for your reference. The details are as follows:

var_export(array('a','b',array('aa','bb','cc')))//这种与var_dump没什么区别
[code]$var =var_export(array('a','b',array('aa','bb','cc')),true)//加上true后,不会再打印出来,而是给了一个变量,这样就可以直接输出; 
echo $var;//此时输出来的形式与var_dump()打印的相似.

Example 2, the code is as follows:

The code is as follows:

$data = array ('name' => 'abc', 'job' => 'programmer','a'=>array('aa','cc','bb'));  
$data = var_export($data,true);  
echo $data;

The output form is as follows:

array (  
'name' => 'abc',  
'job' => 'programmer',  
'a' => 
array (  
0 => 'aa',  
1 => 'cc',  
2 => 'bb',  
),  
)
