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'])) /pic/p>
{
$ip=$_SERVER['HTTP_CLIENT_IP'];
}
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) /pic/p>
{
$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
$ip=$_SERVER['REMOTE_ADDR'];
}
return $ip;
}
4、 日期格式化
function checkDateFormat($date)
{
/pic/p>
if (preg_match ("/^([0-9]{4})-([0-9]{2})-([0-9]{2})$/", $date, $parts))
{
/pic/p>
if(checkdate($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
/pic/p>
$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﹥";
/pic/p>
$xml = simplexml_load_string($xml_string);
/pic/p>
foreach ($xml-﹥molecule as $record)
{
/pic/p>
echo $record['name'], ' ';
/pic/p>
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"; /pic/p>
$dbUser = "xxxx"; /pic/p>
$dbPass = "xxxx"; /pic/p>
$dbDatabase = "xxxx"; /pic/p>
$db = mysql_connect("$dbHost", "$dbUser", "$dbPass") or
die ("Error connecting to database.");
mysql_select_db("$dbDatabase", $db) or die ("Couldn't select the database.");
# This function will send an imitation 404 page if the user
# types in this files filename into the address bar.
# only files connecting with in the same directory as this
# file will be able to use it as well.
function send_404()
{
header('HTTP/1.x 404 Not Found');
print '﹤!DOCTYPE HTML PUBLIC "-/pic/pic/pic/p>
'﹤html﹥﹤head﹥'."n".
'﹤title﹥404 Not Found﹤/title﹥'."n".
'﹤/head﹥﹤body﹥'."n".
'﹤h1﹥Not Found﹤/h1﹥'."n".
'﹤p﹥The requested URL '.
str_replace(strstr($_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;
}
}
?﹥
/pic/p>
﹤?php
include 'functions.php';
if(unzip('zipedfiles/test.zip','unziped/myNewZip'))
echo 'Success!';
else
echo 'Error';
?﹥
