Share a few very useful snippets of PHP code

1. Send SMS

Invoke the Textmagic++ API.

Include 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,

' Password ' => $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)

2. Find addresses based on IP

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;

}

}

3. Display the source code of the Web page

$lines = File (' http://google.com/');

foreach ($lines as $line _num => $line) {

loop thru each line and prepend line numbers

echo "line #{$line _num} :". Htmlspecialchars ($line). "
\ n ";

}

4. Check that the server is using HTTPS

if ($_server[' HTTPS ']!= "on") {

echo "This isn't HTTPS";

}else{

echo "This is HTTPS";

}

5. Show the number of Facebook fans

function Fb_fan_count ($facebook _name) {

Example:https://graph.facebook.com/digimantra

$data = Json_decode (file_get_contents ("https://graph.facebook.com/". $facebook _name));

Echo $data->likes;

}

6. Detect the main color of the picture

$i = Imagecreatefromjpeg ("Image.jpg");

for ($x =0; $x

for ($y =0; $y

$rgb = Imagecolorat ($i, $x, $y);

$r = ($rgb >>) & 0xFF;

$g = ($rgb >> & 0xFF;

$b = $rgb & 0xFF;

$rTotal + + $r;

$gTotal + + $g;

$bTotal + + $b;

$total + +;

}

}

$rAverage = Round ($rTotal/$total);

$gAverage = Round ($gTotal/$total);

$bAverage = Round ($bTotal/$total);

7. Get Memory usage information

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

*/

8. Use Gzcompress () to compress data

$string =

"Lorem ipsum dolor sit amet, consectetur

Adipiscing elit. Nunc ut elit id mi ultricies

Adipiscing. Nulla Facilisi. Praesent Pulvinar,

Sapien vel feugiat vestibulum, nulla dui pretium,

Non ultricies elit lacus quis ante. Lorem ipsum dolor

Sit amet, consectetur adipiscing elit. Aliquam

Pretium ullamcorper Urna quis iaculis. Etiam ac Massa

Sed turpis tempor luctus. Curabitur sed nibh eu elit

Mollis Congue. Praesent ipsum diam, Consectetur vitae

Ornare A, aliquam a nunc. In ID magna pellentesque

Tellus posuere adipiscing. Sed non mi metus, at Lacinia

Augue. Sed magna Nisi, ornare in mollis, mollis

Sed nunc. Etiam at Justo in Leo Congue mollis.

Nullam in Neque eget metus hendrerit scelerisque

EU non enim. Ut malesuada lacus eu nulla bibendum

ID euismod urna sodales. ";

$compressed = gzcompress ($string);

echo "Original size:". Strlen ($string). " \ n ";

/* Prints

Original size:800

*/

echo "Compressed size:". Strlen ($compressed). " \ n ";

/* Prints

Compressed size:418

*/

Getting it back

$original = gzuncompress ($compressed);

9. Use PHP to do whois checking

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];

Lists

Like this on Wikipedia:

//

Http://de.wikipedia.org/wiki/Whois

//

$servers = Array (

"Biz" => "Whois.neulevel.biz",

"com" => "whois.internic.net",

"Us" => "whois.nic.us",

"Coop" => "Whois.nic.coop",

"Info" => "Whois.nic.info",

"Name" => "Whois.nic.name",

"NET" => "Whois.internic.net",

"gov" => "whois.nic.gov",

"Edu" => "Whois.internic.net",

"Mil" => "Rs.internic.net",

"int" => "whois.iana.org",

"AC" => "Whois.nic.ac",

"AE" => "whois.uaenic.ae",

"At" => "Whois.ripe.net",

"Au" => "whois.aunic.net",

"Be" => "whois.dns.be",

"BG" => "Whois.ripe.net",

"BR" => "whois.registro.br",

"BZ" => "whois.belizenic.bz",

"Ca" => "whois.cira.ca",

"CC" => "whois.nic.cc",

"ch" => "whois.nic.ch",

"CL" => "whois.nic.cl",

"cn" => "whois.cnnic.net.cn",

"CZ" => "whois.nic.cz",

"De" => "whois.nic.de",

"FR" => "whois.nic.fr",

"Hu" => "whois.nic.hu",

"IE" => "whois.domainregistry.ie",

"Il" => "whois.isoc.org.il",

"In" => "whois.ncst.ernet.in",

"IR" => "whois.nic.ir",

"MC" => "Whois.ripe.net",

"To" => "whois.tonic.to",

"TV" => "Whois.tv",

"Ru" => "whois.ripn.net",

"org" => "whois.pir.org",

"Aero" => "Whois.information.aero",

"NL" => "whois.domain-registry.nl"

);

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 not connect to '. $nic _server. '!'); }

return $output;

}

10. Send php error via email

Our custom error handler

function Nettuts_error_handler ($number, $message, $file, $line, $vars) {

$email = "

　　

An error ($number) occurred in line

　　$line and in the file: $file.

　　

$message

";

$email. = "

" . Print_r ($vars, 1). "

";

$headers = ' content-type:text/html; Charset=iso-8859-1 '. "\ r \ n";

Email the error to someone ...

Error_log ($email, 1, ' you@youremail.com ', $headers);

Make sure so you decide and respond to errors (on the user ' s side)

Either echo an error message, or kill the entire project. Up to you ...

The code below ensures that we are only "die" if the error is more than

Just a NOTICE.

if ($number!== e_notice) && ($number < 2048)) {

Die ("There was") error. Please try again later. ");

}

}

We should use our custom function to handle errors.

Set_error_handler (' Nettuts_error_handler ');

Trigger an error ... (Var doesn ' t exist)

Echo $somevarthatdoesnotexist;
