testing php function with poster extention - php

Question

I made a simple API to get the data from the database to be viewd at android app
I have a Problem testing my php functions
example of the functions:-
<?php
include 'json_config.php';
function get_city(){
mysql_query("SET NAMES utf8;");
mysql_query("SET CHARACTER_SET utf8;");
$return=array();
//$country_name=$_POST['country_name'];
// get all products from products table
$result = mysql_query("SELECT *FROM city") or die(mysql_error());
// check for empty result
if (mysql_num_rows($result) > 0) {
// looping through all results
// products node
$response["city"] = array();
while ($row = mysql_fetch_array($result)) {
// temp user array
// Full texts id dead_name masged_name gender salah notes date city_name hour min
$region_subscribt = array();
$region_subscribt["id"] = $row["id"];
$region_subscribt["city_name"] = $row["city_name"];
$region_subscribt["region_name"] = $row["notes"];
$region_subscribt["notes"] = $row["country_name"];
// push single product into final response array
array_push($response["city"], $region_subscribt);
}
// echoing JSON response
echo json_encode($response,JSON_UNESCAPED_UNICODE);
} else {
// no products found
$response["fail"] = 0;
// echo no users JSON
echo json_encode($response,JSON_UNESCAPED_UNICODE);
}
}//end of the function
// get_city();
?>
when I using poster extention with firefox and put at the content , I got no data
when I put at the content
getcity();
but when I call the function inside the php file I got the data correctly !
How to pass the values at the httprequest to use the returned json at another app !

You need to send the method name as a parameter not as a content and then check the method name and call the code you need.
see this snapshot
if(isset($_GET['method_name']) && $_GET['method_name']) == 'get_city') {
get_city();
}
you also need to set the content type as following
header('Content-type: application/json');
your final code will be something like this
<?php
include 'json_config.php';
function get_city(){
mysql_query("SET NAMES utf8;");
mysql_query("SET CHARACTER_SET utf8;");
$return=array();
//$country_name=$_POST['country_name'];
// get all products from products table
$result = mysql_query("SELECT *FROM city") or die(mysql_error());
header('Content-type: application/json');
// check for empty result
if (mysql_num_rows($result) > 0) {
// looping through all results
// products node
$response["city"] = array();
while ($row = mysql_fetch_array($result)) {
// temp user array
// Full texts id dead_name masged_name gender salah notes date city_name hour min
$region_subscribt = array();
$region_subscribt["id"] = $row["id"];
$region_subscribt["city_name"] = $row["city_name"];
$region_subscribt["region_name"] = $row["notes"];
$region_subscribt["notes"] = $row["country_name"];
// push single product into final response array
array_push($response["city"], $region_subscribt);
}
// echoing JSON response
echo json_encode($response,JSON_UNESCAPED_UNICODE);
} else {
// no products found
$response["fail"] = 0;
// echo no users JSON
echo json_encode($response,JSON_UNESCAPED_UNICODE);
}
}//end of the function
if(isset($_GET['method_name']) && $_GET['method_name']) == 'get_city') {
get_city(); }
?>
