<?php echo $_POST["name"] ; ?> Why we need Square Bracket here ?

Question

i wanna know why this syntax is used?

Answer 1

Every array needs subscript as a square brackets [ ] to show the value at particular index. Since $_POST is an array, it needs square brackets.

Answer 2

In form handling where you have to store values of name, email, mobile number, age, gender, passwords, about, photo etc.

All those values are held by a single array, which is either $_GET or $_POST

Answer 3

Cuz internally $_POST is an array which stores all values u want to pass using post

Answer 4

$_POST is an associative array. As per the language design, accessing elements of such an array is performed via the square bracket notation:

echo $_POST["key"];
