Question

function backup_tables($host,$user,$pass,$name,$tables = 'collection_detail, coupon_detail, coupon_redeem_log, coupon_shopping_cart, customer_address, customer_detail, dairy_sales_detail, delivery_types, item_detail, locked_date, user_login_detail')
{


$link = mysqli_connect($host,$user,$pass,$name);

//get all of the tables
if($tables == '*')
{
    $tables = array();
    $result = mysqli_query($link, 'SHOW TABLES');
    while($row = mysqli_fetch_row($result))
    {
        $tables[] = $row[0];
    }
}
else
{
    $tables = is_array($tables) ? $tables : explode(',',$tables);
}

//cycle through
foreach($tables as $table)
{
    $result = mysqli_query($link, 'SELECT * FROM '.$table);
    $num_fields = mysqli_num_fields($result);
    $return ="";
    $return.= 'DROP TABLE IF EXISTS '.$table.';';
    $row2 = mysqli_fetch_row(mysqli_query($link,'SHOW CREATE TABLE '.$table));
    $return.= "\n\n".$row2[1].";\n\n";

    for ($i = 0; $i < $num_fields; $i++) 
    {
        while($row = mysqli_fetch_row($result))
        {
            $return.= 'INSERT INTO '.$table.' VALUES(';
            for($j=0; $j < $num_fields; $j++) 
            {
                $row[$j] = addslashes($row[$j]);
                $row[$j] = ereg_replace("\n","\\n",$row[$j]);
                if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
                if ($j < ($num_fields-1)) { $return.= ','; }
            }
            $return.= ");\n";
        }
    }
    $return.="\n\n\n";
}}

有人可以告诉我正确替换ereg替换。

Answer 1

您需要将ereg_replace替换为preg_replace，请参阅以下示例：

print $input."<hr>".ereg_replace('/&/', ':::', $input);

成为

print $input."<hr>".preg_replace('/&/', ':::', $input);

不推荐使用：函数ereg_replace（）在第44行的C：\ wamp \ www \ boot \ backup.php中已弃用
