PHP 7 Data Structures and Algorithms

Implementing struct using a PHP array

As we already know, a struct is a complex data type where we define multiple properties as a group so that we can use it as a single data type. We can write a struct using a PHP array and class. Here is an example of a struct using a PHP array:

$player = [     "name" => "Ronaldo",     "country" => "Portugal",     "age" => 31,     "currentTeam" => "Real Madrid" ]; 

It is simply an associative array with keys as string. A complex struct can be constructed using single or more constructs as its properties. For example using the player struct, we can use a team struct:

$ronaldo = [     "name" => "Ronaldo",     "country" => "Portugal",     "age" => 31,     "currentTeam" => "Real Madrid" ]; $messi = [     "name" => "Messi",  "country" ...
