This article illustrates the usage of the var_export function in the php format output file. Share it for your reference. The details are as follows:

var_export:php 4 > = 4.2.0, php 5

var_export--Outputs or returns a string representation of a variable.

Description: mixed var_export (mixed expression [, bool return])

This function returns structural information about the variable passed to it, similar to var_dump (), except that the representation it returns is a legitimate php code, which you can return by setting the second argument of the function to true.

Example:

var_export(array('a','b',array('aa','bb','cc')))// This kind of relationship with var_dump That makes no difference 
[code]$var =var_export(array('a','b',array('aa','bb','cc')),true)// Plus true Posterior , It won't print out again , But gave it to 1 Variable , So you can output directly ;
echo $var;// The output form at this time is the same as that of var_dump() Similarity of printing .

Example 2, 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', 
), 
)

I hope this article is helpful to everyone's PHP programming.
