How to Append Key-Value Pairs to PHP Arrays?

Appending Key-Value Pairs to PHP Arrays

In PHP, while the array_push() function is commonly used to add elements to an array, it cannot be directly employed for associative arrays, which contain key-value pairs.

To address this issue, the print_r function can be used to print the output of an array, as seen in the example:

$GET = array();
$key = 'one=1';
$rule = explode('=', $key);
$GET[$rule[0]] = $rule[1]; // Manually assign key-value pair

This code uses the explode() function to split the key into its components, and then manually assigns the key and value to the $GET array using the syntax $arrayname[indexname] = $value.

While array_push() is not directly applicable to associative arrays, the above approach provides a simple and straightforward method to append key-value pairs to these data structures.
