Get variables with PHP in a Turbo Pascal way

Question

In Turbo Pascal we have the read(); function. Is there a function to get variables, sent to any script on PHP?

Answer 1

The Turbo Pascal read() and readln() functions read from file. If no filename is specified, they read from standard input.

In PHP, you have to open the file first, then read from the file handle allocated on open: the equivalent of standard input in PHP is php://input, so something like:

$filename = "php://input";
$handle = fopen($filename, "r");
$contents = fread($handle, 1024);
fclose($handle);

But note that it's not particularly practical to do this from a web interface, only from the CLI

Answer 2

Are you maybe looking for the eval() function? http://php.net/manual/en/function.eval.php
