[2]在PHP3中实现SESSION的功能（一）
    来源: 互联网  发布时间: 2013-11-30
SESSION函数库：session.inc.php3

<?php
if (!isset($__session_inc__)){
$__session_inc__=1;
//require("cookie.inc.php3");
# -------------------------------------------------------------------  
# Session Management v1.0 21.6.1998  
# (c) Wild Karl Heinz <kh.wild@wicom.at>  
#  
# This Include handle Session based variable handling  
#  
# Please feel free and use it. If you make it more functional  
# it would be nice to send me a copy.  
#  
# Don't forget - Mysql_connect !  
#  
# The database structure  
# Table structure for table 'session'  
#  
# CREATE TABLE session (  
# id int(11) DEFAULT '0' NOT NULL auto_increment,  
# sid varchar(20) DEFAULT '' NOT NULL,  
# val blob,  
# times timestamp(14),  
# PRIMARY KEY (id),  
# KEY sid (sid),  
# UNIQUE sid_2 (sid)  
# );  
#  
# You'll miss here a cron job to delete the old sessions from db  
# -------------------------------------------------------------------  

// 请注意上面被注释掉的CREATE TABLE语句，
// 你需要在你所使用的数据库上执行这条语句，
// 表名也可以不是session，那么就需要设置下面的$sess_table变量了。

// 此处你需要设置库名，和表名。
// 不过一般建议就使用session作为表名
$sess_db = 'dbname';  
$sess_table = 'session';  

# ----------------------------------------------------  
# Session_CheckID - 检查、设置并返回 Session-ID  
# 参数......: cookie保存时间(以分钟计)
# 也可不设置表示这个 cookie 只在当前session 有效
# 这其实就象ASP中SESSION的时效一样。
# 返回值....: 一个唯一的Session-ID （作为cookie存储）
# ----------------------------------------------------  
function Session_CheckID( $min )  
{
global $sess_sid;  

if( !$sess_sid ) {  
$sess_sid = uniqid( SC ); //取得一个唯一的随机数
/*
if( $min > 0 ) {  
SetCookie("sess_sid", $sess_sid, time()+($min*60), "/", "", 0 );  
}  
else {  
SetCookie("sess_sid", $sess_sid, "", "/", "", 0 );  
}  
上面是原先的代码，会出错。所以另外用了一个更好的函数。
函数库：cookie.inc.php3
*/
jssetcookie("sess_sid",$sess_sid,$min);
return( false );  
}  
else {  
return( true );  
}  
}  

# ----------------------------------------------------------  
# str2arr - 将字符串转换成session数组
# 参数.....: string
# 返回值...: 全局数组（其实就是session)  
#本函数用途：将字符串转换成session数组
#如"session[username]=yourid&session[userpass]=12345"
#将会被转换成下面的数组
# session[username]="yourid"
# session[userpass]="12345"
#请注意函数split(),each(),list(),eval()的用法。
# ----------------------------------------------------------  
function str2arr( $ts )  
{  
global $session;  

$vals = split( "&", $ts );  
while( list($key,$val) = each($vals) ) {  
list( $name, $wert ) = split( "=", $val );  
if( $val ) eval( "$$name = "$wert";" );  
}  
}  

# ----------------------------------------------------------  
# session_read() - 从SESSION表中取数据，转换成session数组  
# 参数........: 无
# 返回值......: 如果读出数据，返回 true ，否则返回 false
#注意.........: 用到了str2arr()这个函数
# ----------------------------------------------------------  
function session_read()  
{  
# Hash array to keep session-variables  
global $session;  
global $sess_sid, $sess_db, $sess_table, $sess_error;  

$sel = "Select val from $sess_table where sid = '$sess_sid'";  
$res = mysql_db_query( $sess_db, $sel );  
if( mysql_numrows( $res ) ) {  
$val = mysql_result( $res, 0, "val" );  
str2arr( $val );  
mysql_free_result( $res );  
return( true );  
}  
else {  
return( false );  
$sess_error = mysql_error();  
}  
}  

# ------------------------------------------------------  
# Split_Array() - 将session数组转换成字符串
# 参数.......: 数组
# 返回值.....: 数组转换得来的字符串  
#  
# Thanks to Rasmus (这人好象是PHP的发明人)
# 注意:将session数组转换成字符串
#如session[username]="yourid"
# session[userpass]="12345"
#将会被转换成"session[username]=yourid&session[userpass]=12345"
#同时该函数考虑到了数组的某个元素也是数据的情况
#这个函数被设计成一个递归函数
# ------------------------------------------------------  
function Split_Array( $arr, $a = "", $b = "", $c = "" )  
{  
while( list( $key, $val ) = each( $arr ) ) {  
if( is_array( $val ) ) {

( strlen( $b ) ? $b : ( strlen( $a ) ? $key : "" ) ),  
( strlen( $c ) ? $c : ( strlen( $b ) ? $key : "" ) ) );  
}  
else {  
$ts .= "session";  
$ts .= $a ? "[$a]" : "";  
$ts .= $b ? "[$b]" : "";  
$ts .= $c ? "[$c]" : "";  
$ts .= "[$key]=$val&";  
}  
}  
return( $ts );  
}  

# ---------------------------------------------------  
# session_write - 将session数组转换成字符串，再存到session表中  
# 参数.: 无
# 返回值...: 如果存入正常返回 true ，否则返回 false
# ---------------------------------------------------  
function session_write()  
{  
# Hash array to keep session-variables  
global $session;  

global $sess_sid, $sess_db, $sess_table;  
global $sess_error;  

# if you like to delete a session-cookie  
# you must check it before writting the session  
# array  

if( !$sess_sid ) { session_checkid( 0 ); }  

$ts = Split_Array( $session );  
if( $ts > "" ) { $ts = substr( $ts, 0, strlen( $ts ) - 1 ); }  
$res = mysql_db_query( $sess_db, "Select * from session where sid = '$sess_s'");  
if( mysql_numrows( $res ) == 0 ) {  
$sel = "Insert into $sess_table ( id, sid, val, times ) ";  
$sel .= "values( 0, '$sess_sid', '$ts', NULL )";  
}  
else {  
$sel = "Update $sess_table set val = '$ts', ";  
$sel .= "times = NULL where sid = '$sess_sid'";  
}  
if( !mysql_db_query( $sess_db, $sel ) ) {  
$sess_error = mysql_error();  
return( false );  
}  
else { return( true ); }  
}  

# ---------------------------------------------  
# session_del - 清除当前所有的session
# 并删除session表中和当前session有关的记录  
# 参数.....: 一个随机的session id  
# 返回值...: 无
# ---------------------------------------------  
function session_del()  
{  
global $session, $sess_db, $sess_table, $sess_sid;  

$sel = "Delete from $sess_table where sid = '$sess_sid'";
