本文實例講述了PHP中基本HTTP認證技巧。分享給大家供大家參考。具體分析如下：
通過組合.htaccess文件和.htpasswd文件被用來阻止用戶訪問某些服務器上的目錄。這些文件包含有關用戶被允許訪問一個目錄和自己的密碼信息。 HTTP身份驗證可以通過發送特殊的HTTP header信息，而不用使用.htaccess文件
復制代碼代碼如下:
<?php
if (!isset($_SERVER['PHP_AUTH_USER'])) {
header("WWW-Authenticate: Basic realm=/"My Private Area/"");
header("HTTP/1.0 401 Unauthorized");
print "You need valid credentials to get access!/n";
exit;
} else {
if (($_SERVER['PHP_AUTH_USER'] == 'mani') && ($_SERVER['PHP_AUTH_PW'] == 'w#m3nt0r')) {
print "Welcome to the private area!";
} else {
header("WWW-Authenticate: Basic realm=/"My Private Area/"");
header("HTTP/1.0 401 Unauthorized");
print "You need valid credentials to get access!/n";
exit;
}
}
?>
if (!isset($_SERVER['PHP_AUTH_USER'])) {
header("WWW-Authenticate: Basic realm=/"My Private Area/"");
header("HTTP/1.0 401 Unauthorized");
print "You need valid credentials to get access!/n";
exit;
} else {
if (($_SERVER['PHP_AUTH_USER'] == 'mani') && ($_SERVER['PHP_AUTH_PW'] == 'w#m3nt0r')) {
print "Welcome to the private area!";
} else {
header("WWW-Authenticate: Basic realm=/"My Private Area/"");
header("HTTP/1.0 401 Unauthorized");
print "You need valid credentials to get access!/n";
exit;
}
}
?>
希望本文所述對大家的php程序設計有所幫助。
