I was analyzing a PHP code, and a script was used extract .
I searched in some PHP documents and the examples are a bit abstract and unfortunately I did not realize much.
I would like in a general case to know what extract does in PHP? (If possible a concrete example).
Get an associative array and declare variables, named after the keys, and the contents of the variable, the key value of the array.
Here's an example:
$teste = ["variavel" => "valor da variável"];
extract($teste);
echo $variavel; //vai imprimir "valor da variavel"
Here are some more intuitive examples.
