PHP curly braces in array notation

Question

I\'d just come across a very weird bit of php code:

$oink{\'pig\'} = 1;
var_dump($oink);

$oink{\'pig\'} = \'123123\';
echo $oink{\'pig\'}; /* => 123123 *         


        

Answer 1

Array and string offset access using curly braces is officially deprecated from PHP7.4 Ref: https://www.php.net/manual/en/migration74.deprecated.php
