PHP code for obtaining the IP address location program-PHP source code

PHP uses related functions and regular expressions to obtain information on a specified webpage when obtaining IP addresses. Below I will sort out several common interfaces and obtaining methods, for more information, see.

Script ec (2); script

Use php file_get_contents to obtain the IP address and obtain the geographic location. See the following code:

Use file_get_contents and fopen to enable allow_url_fopen. Method: Edit php. ini and set allow_url_fopen = On. When allow_url_fopen is disabled, neither fopen nor file_get_contents can open remote files.

Example

The Code is as follows:
Function get_ip_place () { $ Ip = file_get_contents ("http://fw.qq.com/ipaddress "); $ Ip = str_replace ('"','', $ ip ); $ Ip2 = explode ("(", $ ip ); $ A = substr ($ ip2 [1], 0,-2 ); $ B = explode (",", $ ); Return $ B; }

There is another way:

Let's see.

The Code is as follows:
Function get_ip_arr () { $ Ip = file_get_contents ("http://fw.qq.com/ipaddress "); Preg_match_all ("/" (. *) "/", $ ip, $ arr ); Return $ arr; }

The returned result is an array, which can be any region or ip address.

/Use curl:

Use curl to enable curl. Method: Modify php. ini in windows, remove the semicolon before extension = php_curl.dll, and copy ssleay32.dll and libeay32.dll to C:/WINDOWS/system32. Install curl extension in Linux.

Example

The Code is as follows:

Function getIPLoc ($ queryIP ){ $ Url = 'HTTP: // ip.qq.com/cgi-bin/searchip? Searchip1 = '. $ queryIP; $ Ch = curl_init ($ url ); Curl_setopt ($ ch, CURLOPT_ENCODING, 'gb2312 '); Curl_setopt ($ ch, CURLOPT_TIMEOUT, 10 ); Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true); // get data and return $ Result = curl_exec ($ ch ); $ Result = mb_convert_encoding ($ result, "UTF-8", "gb2312"); // code conversion, otherwise garbled Curl_close ($ ch ); Preg_match ("@(.*) @ IU ", $ result, $ ipArray ); $ Loc = $ ipArray [1]; Return $ loc; }
