This article describes the method of recursively escaping arrays in PHP in the form of examples and shares it with you for your reference. The specific method is as follows:
The need to convert arrays to xml in PHP is common, and there are many implementation methods. Baidu looked for various implementation methods, but basically they borrowed some components. I wrote a string grouping method myself, which supports multi-dimensional arrays. This is for reference only, please feel free to let us know if there are any deficiencies!

The above is the implementation method. The first parameter is the array you want to convert. The second optional parameter sets whether to add a root node. It is required by default.
Test code:
Copy the code. The code is as follows:
$arr=array('a'=>'aaa','b'=>array('c'=>'1234' , 'd' => "asdfasdf"));
echo arr2xml($arr);
The result after executing the code is:
Copy the code. The code is as follows:
