PHP GET and POST

PHP uses $_GET and $_POST to collect form data submitted through HTML forms. $_GET appends data to the URL while $_POST sends data in the HTTP request body.

PHP $_GET और $_POST का उपयोग HTML forms के माध्यम से भेजे गए डेटा को प्राप्त करने के लिए किया जाता है। $_GET डेटा को URL में जोड़ता है जबकि $_POST डेटा को request body में भेजता है।
