PHP開發常用的10段代碼

　　PHP是一種通用開源腳本語言。語法吸收了C語言、Java和Perl的特點，下文是為大家精選的PHP開發常用的10段代碼，歡迎大家閱讀。

　　1、使用PHP Mail函數發送Email

　　$to = "viralpatel.net@gmail.com";

　　$subject = "VIRALPATEL.net";

　　$body = "Body of your message here you can use HTML too. e.g. ﹤br﹥ ﹤b﹥ Bold ﹤/b﹥";

　　$headers = "From: Peter ";

　　$headers .= "Reply-To: info@yoursite.com ";

　　$headers .= "Return-Path: info@yoursite.com ";

　　$headers .= "X-Mailer: PHP5 ";

　　$headers .= 'MIME-Version: 1.0' . " ";

　　$headers .= 'Content-type: text/html; charset=iso-8859-1' . " ";

　　mail($to,$subject,$body,$headers);

　　?﹥

　　2、PHP中的64位編碼和解碼

　　function base64url_encode($plainText) {

　　$base64 = base64_encode($plainText);

　　$base64url = strtr($base64, '+/=', '-_,');

　　return $base64url;

　　}

　　function base64url_decode($plainText) {

　　$base64url = strtr($plainText, '-_,', '+/=');

　　$base64 = base64_decode($base64url);

　　return $base64;

　　}

　　3、獲取遠程IP地址

　　function getRealIPAddr()

　　{

　　if (!empty($_SERVER['HTTP_CLIENT_IP'])) //check ip from share internet

　　{

　　$ip=$_SERVER['HTTP_CLIENT_IP'];

　　}

　　elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) //to check ip is pass from proxy

　　{

　　$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];

　　}

　　else

　　{

　　$ip=$_SERVER['REMOTE_ADDR'];

　　}

　　return $ip;

　　}

　　4、日期格式化

　　function checkDateFormat($date)

　　{

　　//match the format of the date

　　if (preg_match ("/^([0-9]{4})-([0-9]{2})-([0-9]{2})$/", $date, $parts))

　　{

　　//check weather the date is valid of not

　　if(checkdate($parts[2],$parts[3],$parts[1]))

　　return true;

　　else

　　return false;

　　}

　　else

　　return false;

　　}

　　5、驗證Email

　　$email = $_POST['email'];

　　if(preg_match("~([a-zA-Z0-9!#$%&'*+-/=?^_`{|}~])@([a-zA-Z0-9-]).

　　([a-zA-Z0-9]{2,4})~",$email)) {

　　echo 'This is a valid email.';

　　} else{

　　echo 'This is an invalid email.';

　　}

　　6、在PHP中輕松解析XML

　　//this is a sample xml string

　　$xml_string="﹤?xml version='1.0'?﹥

　　﹤moleculedb﹥

　　﹤molecule name='Benzine'﹥

　　﹤symbol﹥ben﹤/symbol﹥

　　﹤code﹥A﹤/code﹥

　　﹤/molecule﹥

　　﹤molecule name='Water'﹥

　　﹤symbol﹥h2o﹤/symbol﹥

　　﹤code﹥K﹤/code﹥

　　﹤/molecule﹥

　　﹤/moleculedb﹥";

　　//load the xml string using simplexml function

　　$xml = simplexml_load_string($xml_string);

　　//loop through the each node of molecule

　　foreach ($xml-﹥molecule as $record)

　　{

　　//attribute are accessted by

　　echo $record['name'], ' ';

　　//node are accessted by -﹥ operator

　　echo $record-﹥symbol, ' ';

　　echo $record-﹥code, '﹤br /﹥';

　　}

　　7、數據庫連接

　　﹤?php

　　if(basename(__FILE__) == basename($_SERVER['PHP_SELF'])) send_404();

　　$dbHost = "localhost"; //Location Of Database usually its localhost

　　$dbUser = "xxxx"; //Database User Name

　　$dbPass = "xxxx"; //Database Password

　　$dbDatabase = "xxxx"; //Database Name

　　$db = mysql_connect("$dbHost", "$dbUser", "$dbPass") or

　　die ("Error connecting to database.");

　　mysql_select_db("$dbDatabase", $db) or die ("Couldn't select the database.");

　　# This function will send an imitation 404 page if the user

　　# types in this files filename into the address bar.

　　# only files connecting with in the same directory as this

　　# file will be able to use it as well.

　　function send_404()

　　{

　　header('HTTP/1.x 404 Not Found');

　　print '﹤!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"﹥'."n".

　　'﹤html﹥﹤head﹥'."n".

　　'﹤title﹥404 Not Found﹤/title﹥'."n".

　　'﹤/head﹥﹤body﹥'."n".

　　'﹤h1﹥Not Found﹤/h1﹥'."n".

　　'﹤p﹥The requested URL '.

　　str_replace(strstr($_SERVER['REQUEST_URI'], '?'), '', $_SERVER['REQUEST_URI']).

　　' was not found on this server.﹤/p﹥'."n".

　　'﹤/body﹥﹤/html﹥'."n";

　　exit;

　　}

　　# In any file you want to connect to the database,

　　# and in this case we will name this file db.php

　　# just add this line of php code (without the pound sign):

　　# include"db.php";

　　?﹥

　　8、創建和解析JSON數據

　　$json_data = array ('id'=﹥1,'name'=﹥"rolf",'country'=﹥'russia',

　　"office"=﹥array("google","oracle"));

　　echo json_encode($json_data);

　　9、處理MySQL時間戳

　　$query = "select UNIX_TIMESTAMP(date_field) as mydate

　　from mytable where 1=1";

　　$records = mysql_query($query) or die(mysql_error());

　　while($row = mysql_fetch_array($records))

　　{

　　echo $row;

　　}

　　10、解壓縮Zip文件

　　﹤?php

　　function unzip($location,$newLocation){

　　if(exec("unzip $location",$arr)){

　　mkdir($newLocation);

　　for($i = 1;$i﹤ count($arr);$i++){

　　$file = trim(preg_replace("~inflating: ~","",$arr[$i]));

　　copy($location.'/'.$file,$newLocation.'/'.$file);

　　unlink($location.'/'.$file);

　　}

　　return TRUE;

　　}else{

　　return FALSE;

　　}

　　?﹥

　　//Use the code as following:

　　﹤?php

　　include 'functions.php';

　　if(unzip('zipedfiles/test.zip','unziped/myNewZip'))

　　echo 'Success!';

　　else

　　echo 'Error';

　　?﹥
