1、使用PHP Mail函数发送Email, ]# \+^" _3f&b& |-\;J$to = "viralpatel.net@gmail.com";5 _1d) \2H,r1j*r:^
$subject = "VIRALPATEL.net";' T'A" _.{2p7u"T6A* |
$body = "Body of your message here you can use HTML too. e.g. ﹤br﹥ ﹤b﹥ Bold ﹤/b﹥"; 聽
$headers = "From: Peter\r\n"; 聽
$headers .= "Reply-To: info@yoursite.com\r\n"; 聽
$headers .= "Return-Path: info@yoursite.com\r\n"; 聽
$headers .= "X-Mailer: PHP5\n"; 聽
$headers .= 'MIME-Version: 1.0' . "\n";# {1k3K-v0K-i-m!k
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";: U9Y2H1[3|"/V3A* |
mail($to,$subject,$body,$headers);1 Q+D1y4B$b
?﹥0 G4w%?,@#f%|*h

2、PHP中的64位编码和解码2z6~:I$D+__function base64url_encode($plainText) {v" U)u;C/\" |$r
$base64 = base64_encode($plainText);8 [2T2}2_,F:F
$base64url = strtr($base64, '+/=', '-_,');9 A.{%B*y4s'o$W
return $base64url;' g"d"r2o)u5{9@-{4f
}
4|2\*V1j5v2V) ^5d9@+K%}
function base64url_decode($plainText) {
$base64url = strtr($plainText, '-_,', '+/=');, e' ]-F6a#J
$base64 = base64_decode($base64url);+k:F& |$N2v"U)p
return $base64;8 j$G&R(c/z"y3r
}聽

3、获取远程IP地址, `0K-@._9|2}:W3nZZfunction getRealIPAddr()3 V/n9~6@* {,]
{v: R&O5m*t8u!g
if (!empty($_SERVER['HTTP_CLIENT_IP']))//check ip from share internet3 [6H7K:H,k3]
{
$ip=$_SERVER['HTTP_CLIENT_IP'];
}& O0y"u3C:w#S)H
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))//to check ip is pass from proxy. b3f#h&d! _( [
{5 W1Y&g0m" {$Y9U2x
$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
$ip=$_SERVER['REMOTE_ADDR'];
}
return $ip;* K)L6u2S"p6O9o
}, K+^/D6X!o"M;I!X

4、 日期格式化function checkDateFormat($date)2 i,N%H"T!s:f.o!Y+?)a
{
//match the format of the date
if (preg_match ("/^([0-9]{4})-([0-9]{2})-([0-9]{2})$/", $date, $parts))6 N9h-A,r"T;l
{2 x,i;y$y%[)j2R;Iq
//check weather the date is valid of not1 l5p1h3s1}(d2p
if(checkdate($parts[2],$parts[3],$parts[1])); N0u( \$R"z:a0Y+W8L
return true;
else
return false;
}$ X& ?3Y%b;M6Y
else' t;v$N) ^8?%C/b2~"B! \
return false;

5、验证Email# ]1 }& u+l/]3R$email = $_POST['email'];7 o5f7~/Q.d%@"k5d.f
if(preg_match("~([a-zA-Z0-9!#$%&'*+-/=?^_`{|}~])@([a-zA-Z0-9-])./ N*w3F)I)Q(S) ^/O+z4W
聽([a-zA-Z0-9]{2,4})~",$email)) {
echo 'This is a valid email.';9 Z&F)F6}+r"K$@*V( ?+E
} else{
echo 'This is an invalid email.';
} ; j!f+g3d1|"q*n

6、在PHP中轻松解析XML
