PHP compact() Function

PHP compact() Function


Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP compact() Function.

The built-in compact() function creates an array from variables and their values.

For each of these, compact() looks for a variable with that name in the current symbol table and adds it to the output array such that the variable name becomes the key and the contents of the variable become the value for that key. In short, it does the opposite of extract().

Syntax

Following below is the syntax to use this function -

compact($var1, $var2...);


Parameter Details

Sr.NoParameter & Description
1

var1(Required)

It can be a string with the variable name, or an array of variables.

2

var2(Optional)

It can be a string with the variable name, or an array of variables.


Return Value

This built-in returns the output array with all the variables added to it.

Example

Try out the below example -

<?php
   $city  = "Lekki";
   $state = "LAG";
   $event = "New Year";
   $result = compact("city", "state", "event");
   print_r($result);
?> 

Output

When the above code is executed, it will produce the following result -

Array ( [city] => Lekki [state] => LAG [event] => New Year )
