1) Whois query using PHP-- use PHP to obtain Whois requests

With this code, whois information can be obtained in a specific domain name. Take the domain name as a parameter and display information about all domain names.

The copy code is as follows:

Function whois_query ($domain) {

/ / fix the domain name:

$domain = strtolower (trim ($domain))

$domain = preg_replace ('/ ^ http:\ /\ / iTunes,'', $domain)

$domain = preg_replace ('/ ^ www\. / iTunes,', $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:

/ /

/ / 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 roommates')

}

$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

}

2) Text messaging with PHP using the TextMagic API-use TextMagic API to obtain PHP Test information

TextMagic introduces a powerful core API that can easily send SMS to your mobile phone. The API is subject to payment.

The copy 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

'password' = > $password

))

/ / Send a text message to '999123-4567'

$result = $router- > send ('Wake upbringing, 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-- to obtain memory utilization

This code helps you get memory usage.

The copy 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 < 1000000; $iTunes +) {

$array [] = md5 ($I)

}

/ / let's remove half of the array

For ($I = 0; $I < 1000000; $iTunes +) {

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-- to view the source code of any web page

If you want to view the source code of the web page, just change the URL on the second line and the source code will be displayed on the web page.
