Can you assign multiple variables at once in PHP like you can with Java?
PhpVariablesPhp Problem Overview
I want to create 5 variables of type array all at once. Is this possible? In Java I know you can, but can't find anything about PHP. I'd like to do something like this:
$var1, $var2, $var3, $var4, $var5 = array();
Php Solutions
Solution 1 - Php
Yes, you can.
$a = $b = $c = $d = array();
Solution 2 - Php
Since PHP 7.1 you can use square bracket syntax:
[$var1, $var2, $var3, $var4, $var5] = array(1, 2, 3, 4, 5);

Solution 3 - Php
$c = $b = $a;
is equivalent to
$b = $a;
$c = $b;
therefore:
$var1 = $var2 = $var3 = $var4= $var5 = array();
Solution 4 - Php
$var1 = $var2 = $var3 = $var4= $var5 = array();
Solution 5 - Php
I prefer to use the list function for this task. This is not really a function but a language construct, used to assign a list of variables in one operation.
list( $var1, $var2, $var3 ) = array('coffee', 'brown', 'caffeine');
