Question & Answer :
I person been directed to usage the methodology php://enter alternatively of $_POST once interacting with Ajax requests from JQuery. What I bash not realize is the advantages of utilizing this vs the planetary technique of $_POST oregon $_GET.
The ground is that php://enter returns each the natural information last the HTTP-headers of the petition, careless of the contented kind.
The PHP superglobal $_POST, lone is expected to wrapper information that is both
exertion/x-www-signifier-urlencoded(modular contented kind for elemental signifier-posts) oregonmultipart/signifier-information(largely utilized for record uploads)
This is due to the fact that these are the lone contented varieties that essential beryllium supported by person brokers. Truthful the server and PHP historically don’t anticipate to have immoderate another contented kind (which doesn’t average they couldn’t).
Truthful, if you merely Station a bully aged HTML signifier, the petition seems to be thing similar this:
Station /leaf.php HTTP/1.1 key1=value1&key2=value2&key3=value3
However if you are running with Ajax a batch, this probaby besides contains exchanging much analyzable information with sorts (drawstring, int, bool) and constructions (arrays, objects), truthful successful about instances JSON is the champion prime. However a petition with a JSON-payload would expression thing similar this:
Station /leaf.php HTTP/1.1 {"key1":"value1","key2":"value2","key3":"value3"}
The contented would present beryllium exertion/json (oregon astatine slightest no of the supra talked about), truthful PHP’s $_POST-wrapper doesn’t cognize however to grip that (but).
The information is inactive location, you conscionable tin’t entree it done the wrapper. Truthful you demand to fetch it your self successful natural format with file_get_contents('php://enter') (arsenic agelong arsenic it’s not multipart/signifier-information-encoded).
This is besides however you would entree XML-information oregon immoderate another non-modular contented kind.
