仅使用PHP导出MySQL数据库?mysql

使用php脚本导出数据库的最佳方法。

或添加特定表的第五个参数（数组）：array("mytable1","mytable2","mytable3")用于多个表

select_db($name); $mysqli->query("SET NAMES 'utf8'"); $queryTables = $mysqli->query('SHOW TABLES'); while($row = $queryTables->fetch_row()) { $target_tables[] = $row[0]; } if($tables !== false) { $target_tables = array_intersect( $target_tables, $tables); } foreach($target_tables as $table) { $result = $mysqli->query('SELECT * FROM '.$table); $fields_amount = $result->field_count; $rows_num=$mysqli->affected_rows; $res = $mysqli->query('SHOW CREATE TABLE '.$table); $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."
