使用token的方式,可以控制用户在这个时间内的权限,代码如下:

	function genToken( $len = 32, $md5 = true ) {
# Seed random number generator
# Only needed for PHP versions prior to 4.2
mt_srand( (double)microtime()*1000000 );
# Array of characters, adjust as desired
$chars = array(
'Q', '@', '8', 'y', '%', '^', '5', 'Z', '(', 'G', '_', 'O', '`',
'S', '-', 'N', '<', 'D', '{', '}', '[', ']', 'h', ';', 'W', '.',
'/', '|', ':', '1', 'E', 'L', '4', '&', '6', '7', '#', '9', 'a',
'A', 'b', 'B', '~', 'C', 'd', '>', 'e', '2', 'f', 'P', 'g', ')',
'?', 'H', 'i', 'X', 'U', 'J', 'k', 'r', 'l', '3', 't', 'M', 'n',
'=', 'o', '+', 'p', 'F', 'q', '!', 'K', 'R', 's', 'c', 'm', 'T',
'v', 'j', 'u', 'V', 'w', ',', 'x', 'I', '$', 'Y', 'z', '*'
);
# Array indice friendly number of chars;
$numChars = count($chars) - 1; $token = '';
# Create random token at the specified length
for ( $i=0; $i<$len; $i++ )
$token .= $chars[ mt_rand(0, $numChars) ];
# Should token be run through md5?
if ( $md5 ) {
# Number of 32 char chunks
$chunks = ceil( strlen($token) / 32 ); $md5token = '';
# Run each chunk through md5
for ( $i=1; $i<=$chunks; $i++ )
$md5token .= md5( substr($token, $i * 32 - 32, 32) );
# Trim the token
$token = substr($md5token, 0, $len);
} return $token;
}
//生成的32位随机数
echo genToken()
