【问题描述】:
我正在创建一个模块,我必须在其中将一些表从 db 导出为 sql 文件。我正在使用来自Export MySQL database using PHP only 的参考代码。我想在我的 executeFunction 中使用它,但它有一些核心 PHP 函数,当我将它们放入我的 executeFunction 时这些函数不起作用。但是当我将此脚本放在源文件中并执行文件时,这些工作。我试图在 Symfony 中找到它们的替代功能,但无法做到这一点。如果有人可以在这方面帮助我。我的代码如下:
function Export_Database($host,$user,$pass,$name,$tables=false, $backup_name=false )
{
$conn = Doctrine_Manager::connection();
$rus;
$rus["Users"] = "tbl_users";
$rus["Placemaster"] = "placemaster";
foreach($rus as $key => $value)
{
$result = $conn->fetchAll('SELECT * FROM '.$value);
$fields_amount = $result->field_count; // Gives No Value
$rows_num = $mysqli->affected_rows; // Gives No Value
$res = $conn->execute('SHOW CREATE TABLE '.$value); // Gives something else which the reference code gives.
$TableMLine = $res->fetch_row();
$content = (!isset($content) ? '' : $content) . "\n\n".$TableMLine[1].";\n\n";
for ($i = 0, $st_counter = 0; $i < $fields_amount; $i++, $st_counter=0)
{
while($row = $result->fetch_row())
{ //when started (and every after 100 command cycle):
if ($st_counter%100 == 0 || $st_counter == 0 )
{
$content .= "\nINSERT INTO ".$table." VALUES";
}
$content .= "\n(";
for($j=0; $j<$fields_amount; $j++)
{
$row[$j] = str_replace("\n","\\n", addslashes($row[$j]) );
if (isset($row[$j]))
{
$content .= '"'.$row[$j].'"' ;
}
else
{
$content .= '""';
}
if ($j<($fields_amount-1))
{
$content.= ',';
}
}
$content .=")";
//every after 100 command cycle [or at last line] ....p.s. but should be inserted 1 cycle eariler
if ( (($st_counter+1)%100==0 && $st_counter!=0) || $st_counter+1==$rows_num)
{
$content .= ";";
}
else
{
$content .= ",";
}
$st_counter=$st_counter+1;
}
} $content .="\n\n\n";
}
//$backup_name = $backup_name ? $backup_name : $name."___(".date('H-i-s')."_".date('d-m-Y').")__rand".rand(1,11111111).".sql";
$backup_name = $backup_name ? $backup_name : $name.".sql";
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$backup_name."\"");
echo $content; exit;
}
?>
