19 Ultra-Practical PHP code Snippets _php Instances

1) Whois query using php--using PHP for WHOIS requests

With this code, WHOIS information is available in a specific domain name. Takes the domain name as a parameter and displays information about all domain names.
Copy CodeThe code is as follows: function Whois_query ($domain) {

Fix the domain name:
$domain = Strtolower (Trim ($domain));
$domain = preg_replace ('/^http:\/\//i ', ' ', $domain);
$domain = preg_replace ('/^www\./i ', ' ', $domain);
$domain = explode ('/', $domain);
$domain = Trim ($domain [0]);

Split the TLD from domain name
$_domain = Explode ('. ', $domain);
$lst = count ($_domain)-1;
$ext = $_domain[$lst];

You find resources and lists
Like these on Wikipedia:

);

if (!isset ($servers [$ext])) {
Die (' error:no matching NIC server found! ');
}

$nic _server = $servers [$ext];

$output = ";

Connect to WHOIS Server:
if ($conn = Fsockopen ($nic _server, 43)) {
Fputs ($conn, $domain. " \ r \ n ");
while (!feof ($conn)) {
$output. = Fgets ($conn, 128);
}
Fclose ($conn);
}
else {die (' error:could does connect to '. $nic _server. '!'); }

return $output;
}
2) Text Messaging with PHP using the textmagic api--use the textmagic API to get PHP test information

The

Textmagic introduces a powerful core API that makes it easy to send SMS to your phone. The API is required for a fee. The
copy Code code is as follows:
The Textmagic PHP lib
require (' textmagic-sms-api-php/textmagicapi.php ');

//Set the username and password information
$username = ' myusername ';
$password = ' mypassword ';

//Create A new instance of TM
$router = new Textmagicapi (Array (
' username ' = $username,
' Passwo Rd ' = $password
));

//Send a text message to ' 999-123-4567 '
$result = $router->send (' Wake up! ', Array (9991234567), true);

//Result:result Is:array ([Messages] = Array ([19896128] = 9991234567) [Sent_text] = Wake up! [Parts_count] + 1)
3) Get info about your memory usage--get RAM usage

This code helps you get memory utilization. The
copy Code code is as follows:
echo "Initial:". Memory_get_usage (). "Bytes \ n";
/* Prints
initial:361400 bytes
* *

//Let's use up some memory
for ($i = 0; $i < 100000; $i + +) {
$array []= MD5 ($i);
}

//Let's remove half of the array
for ($i = 0; $i < 100000; $i + +) {
unset ($array [$i]);
}

echo "Final:". Memory_get_usage (). "Bytes \ n";
/* Prints
final:885912 bytes
*/

echo "Peak:". Memory_get_peak_usage (). "Bytes \ n";
/* Prints
peak:13687072 bytes
*/
4) Display source code of any webpage--view any page source codes

If you want to view the source code of the Web page, just change the URL of the second line, and the source code will be displayed on the page.
Copy the Code code as follows: $line) {
Loop thru prepend Line numbers
echo "line #{$line _num}:". Htmlspecialchars ($line). "
\ n ";
}
5) Create data URI ' s--.

By using this code, you can create data URIs, which are useful for embedding images in Html/css, and can help save HTTP requests.
Copy the Code code as follows:
function Data_uri ($file, $mime) {
$contents =file_get_contents ($file);
$base 64=base64_encode ($contents);
echo "Data: $mime; base64, $base 64";
}
6) Detect location by ip--to retrieve geolocation via IP

This code helps you to find a specific IP, just enter the IP on the function parameters, you can detect the location.
Copy CodeThe code is as follows:
function Detect_city ($IP) {

$default = ' UNKNOWN ';

if (!is_string ($IP) | | strlen ($IP) < 1 | | $ip = = ' 127.0.0.1 ' | | $ip = = ' localhost ') $ip = ' 8.8.8.8 '; $curlopt _useragent = ' mozilla/5.0 (Windows; U Windows NT 5.1; En-us; rv:1.9.2) gecko/20100115 firefox/3.6 (. NET CLR 3.5.30729) '; $url = ' http://ipinfodb.com/ip_locator.php?ip= '. UrlEncode ($IP); $ch = Curl_init (); $curl _opt = Array (curlopt_followlocation = 1,
Curlopt_header = 0,
Curlopt_returntransfer = 1,
Curlopt_useragent = $curlopt _useragent,
Curlopt_url = $url,
Curlopt_timeout = 1,
Curlopt_referer = '/http '. $_server[' Http_host '),
);

Curl_setopt_array ($ch, $curl _opt);

$content = curl_exec ($ch);

if (!is_null ($curl _info)) {
$curl _info = Curl_getinfo ($ch);
}

Curl_close ($ch);

if (Preg_match (' {
City: ([^<]*)
}i ', $content, $regs)) {$city = $regs [1];} if (Preg_match (' {

State/province: ([^<]*)

}i ', $content, $regs)) {$state = $regs [1];} if ($city! = "&& $state! =") {$location = $city. ‘, ‘ . $state; return $location; }else{return $default;}}
7) Detect Browser language--View Browser language

The

detects the code scripting language used by the browser. The
copy Code code is as follows: function Get_client_language ($availableLanguages, $default = ' en ') {
if (isset ($ _server[' Http_accept_language ')) {
$langs =explode (', ', $_server[' http_accept_language ']);

foreach ($langs as $value) {
$choice =substr ($value, 0,2);
if (In_array ($choice, $availableLanguages)) {
return $choice;
}
}
}
return $default;
}
8) Check if server is https--to detect if the servers are HTTPS

Copy the code as follows: if ($_server[' HTTPS ']! = "on") {
echo "This was not HTTPS";
}else{
echo "This is HTTPS";
}

foreach ($data as $line) {
Fputcsv ($handle, $line, $delimiter, $enclosure);
}
Rewind ($handle);
while (!feof ($handle)) {
$contents. = Fread ($handle, 8192);
}
Fclose ($handle);
return $contents;
}

10. Find the distance between longitudes and latitudes

Copy CodeThe code is as follows: function getdistancebetweenpointsnew ($latitude 1, $longitude 1, $latitude 2, $longitude 2) {
$theta = $longitude 1-$longitude 2;
$miles = (sin (Deg2rad ($latitude 1)) * Sin (Deg2rad ($latitude 2)) + (cos (Deg2rad ($latitude 1)) * cos (Deg2rad ($latitude 2)) * Cos (Deg2rad ($theta)));
$miles = ACOs ($miles);
$miles = Rad2deg ($miles);
$miles = $miles * 60 * 1.1515;
$feet = $miles * 5280;
$yards = $feet/3;
$kilometers = $miles * 1.609344;
$meters = $kilometers * 1000;
Return compact (' Miles ', ' feet ', ' yards ', ' kilometers ', ' meters ');
}

$point 1 = Array (' lat ' = = 40.770623, ' long ' =-73.964367);
$point 2 = Array (' lat ' = = 40.758224, ' long ' =-73.917404);
$distance = getdistancebetweenpointsnew ($point 1[' lat '), $point 1[' long '], $point 2[' lat '), $point 2[' long ']);
foreach ($distance as $unit = = $value) {
echo $unit. ': '. Number_format ($value, 4). '
';
}

The example returns the following:
