Php Remote json reading method analysis-PHP source code

Data in json format can be directly sent using geturl or post. We will summarize the two methods for reading json data. You can directly use the get url or post method to send json data. We will summarize the two methods for reading json data.

Script ec (2); script

1. Direct output in file form

The Code is as follows:

Header ("Content-type: text/html; charset = UTF-8 "); Function GetCurl ($ url ){ $ Curl = curl_init (); Curl_setopt ($ curl, CURLOPT_RETURNTRANSFER, 1 ); Curl_setopt ($ curl, CURLOPT_URL, $ url ); Curl_setopt ($ curl, CURLOPT_USERAGENT, $ _ SERVER ['HTTP _ USER_AGENT ']); $ Resp = curl_exec ($ curl ); Curl_close ($ curl ); Return $ resp; } $ Resp = GetCurl ("http://www.111cn.net"); // This Is A json Data File $ Resp = json_decode ($ resp, true ); Header ('content-type: application/json '); Echo json_encode ($ resp );

2. Method of receiving post data

The Code is as follows:
$ Json_string = $ _ POST ["txt_json"]; If (ini_get ("magic_quotes_gpc") = "1 ") { $ Json_string = stripslashes ($ json_string ); } $ User = json_decode ($ json_string ); Echo var_dump ($ user ); ?>

In this file, first obtain the value of the POST form field txt_json in the html file, put it in the variable $ json_string, and then judge, if the current PHP is set to magic_quotes_gpc = On, that is, the passed double quotation marks will be escaped, so that the json_decode function cannot be parsed. Therefore, we need to reverse it. Then, use the json_decode function to convert the JSON text into an object, save it in the $ user variable, and finally use echo var_dump ($ user); to output the dump of the object.

HTTP_RAW_POST_DATA of php

The Content-Type = text/xml Type is used to submit an xml document Content to the php server. How can I obtain the POST data.
The RAW/uninterpreted http post information can be accessed: $ GLOBALS ['HTTP _ RAW_POST_DATA '] This is useful in cases where the post Content-Type is not something PHP understands (such as text/xml ).

Because PHP only recognizes the application/x-www.form-urlencoded standard data type by default, the content of the type such as text/xml cannot be parsed as $ _ POST array, so the prototype is retained, it is sent to $ GLOBALS ['HTTP _ RAW_POST_DATA '] for receiving.
Another php: // input can also implement this function.

Php: // input allows reading original POST data. Compared with $ HTTP_RAW_POST_DATA, it puts less pressure on the memory and does not require any special php. ini settings. Php: // input cannot be used for enctype = "multipart/form-data ".

Application

The Code is as follows:
