How to parse array object array in php

PHP is a scripting language used for web development. It is widely used in fields such as website development, data processing and server-side programming. In PHP development, a very common data type is an array of array objects. So, how to parse this data type? This article will introduce it to you.

What is an array of array objects?

In PHP, arrays can be multidimensional, which means they can contain other arrays or objects. Array object array is an array composed of multiple arrays or objects.

For example, we can define an array of array objects as follows:

$array = array(
   array("name"=>"John", "age"=>20),
   array("name"=>"Mary", "age"=>23),
   array("name"=>"Tom", "age"=>25)
);

In this array, each element is another array containing the "name" and "age" attributes.

How to parse an array of array objects?

To parse an array of array objects, we need to use nested foreach statements to iterate through each element and extract its properties.

The following is a common way to parse an array of array objects:

foreach($array as $key => $value){
   foreach($value as $innerKey => $innerValue){
      echo $innerKey . ": " . $innerValue . "<br>";
   }
   echo "<br>";
}

In this example, we use two foreach statements. The first foreach statement iterates through each element in the main array and stores it in the $value variable.

The second foreach statement traverses the array or object in each element and extracts the attributes. In this example, we output the attributes and attribute values ​​to the screen and add a newline character between each element.

Using the above method, we can easily parse arrays of array objects of arbitrary depth.

To sum up, parsing an array of array objects is a very common operation in PHP development. We can simply use nested foreach statements to iterate through each element and extract its properties. If you need to parse an array of array objects in PHP, use the above method.
