Discuz的install文件核心函数

可以将自己写的程序做一个install.php.
Discuz的install文件中的核心函数,相当精简..

<?php
require("connect.inc.php");
$sqlfile = 'test.sql';//sql文件
$fp = fopen($sqlfile, 'rb');
$filesize=filesize($sqlfile);
$sql = fread($fp, $filesize);
fclose($fp);
runquery($sql);
function runquery($sql) {
global $lang, $dbcharset, $tablepre, $db;
$sql = str_replace("\r", "\n", str_replace(' cdb_', ' '.$tablepre, $sql));
$ret = array();
$num = 0;
foreach(explode(";\n", trim($sql)) as $query) {
$queries = explode("\n", trim($query));
foreach($queries as $query) {
$ret[$num] .= $query[0] == '#' || $query[0].$query[1] == '--' ? '' : $query;
}
$num++;
}
unset($sql);
foreach($ret as $query) {
$query = trim($query);
if($query) {
if(substr($query, 0, 12) == 'CREATE TABLE') {
$name = preg_replace("/CREATE TABLE ([a-z0-9_]+) .*/is", "\\1", $query);
echo $lang['create_table'].' '.$name.' ... <font color="#0000EE">'.$lang['succeed'].'</font><br>';
mysql_query(createtable($query, $dbcharset));
} else {
mysql_query($query);
}
}
}
}
?>
