删除用php导出的.csv文件的第一行

Question

我使用此功能将mysql查询下载到.csv文件中：

<?php

function exportMysqlToCsv($table,$filename = 'ready.txt')
{
    $csv_terminated = "\n";
    $csv_separator = ";";
    $csv_enclosed = '';
    $csv_escaped = "\\";
    $sql_query = "SELECT * from table";

    // Gets the data from the database
    $result = mysql_query($sql_query);
    $fields_cnt = mysql_num_fields($result);


    $schema_insert = '';

    for ($i = 0; $i < $fields_cnt; $i++)
    {
        $l = $csv_enclosed . str_replace($csv_enclosed, $csv_escaped . $csv_enclosed,
            stripslashes(mysql_field_name($result, $i))) . $csv_enclosed;
        $schema_insert .= $l;
        $schema_insert .= $csv_separator;
    } // end for

    $out = trim(substr($schema_insert, 0, -1));
    $out .= $csv_terminated;

    // Format the data
    while ($row = mysql_fetch_array($result))
    {
        $schema_insert = '';
        for ($j = 0; $j < $fields_cnt; $j++)
        {
            if ($row[$j] == '0' || $row[$j] != '')
            {

                if ($csv_enclosed == '')
                {
                    $schema_insert .= $row[$j];
                } else
                {
                    $schema_insert .= $csv_enclosed .
                    str_replace($csv_enclosed, $csv_escaped . $csv_enclosed, $row[$j]) . $csv_enclosed;
                }
            } else
            {
                $schema_insert .= '';
            }

            if ($j < $fields_cnt - 1)
            {
                $schema_insert .= $csv_separator;
            }
        } // end for

        $out .= $schema_insert;
        $out .= $csv_terminated;
    } // end while

    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Content-Length: " . strlen($out));
    // Output to browser with appropriate mime type, you choose ;)
    header("Content-type: text/x-csv");
    //header("Content-type: text/csv");
    //header("Content-type: application/csv");
    header("Content-Disposition: attachment; filename=$filename");
    echo $out;
    exit;

}

?>

.csv文件已下载，但它有一个标题。我想将此标题从文件中删除。
