How to PHP Export Serialized Data to Excel - php

Question

is there any other way to extract serialized data from sql to excel? I tried to do this
<?php
$hostname_dbconnect = "localhost";
$database_dbconnect = "upload_dodwnload";
$username_dbconnect = "root";
$password_dbconnect = "";
$dbconnect = mysql_pconnect($hostname_dbconnect, $username_dbconnect, $password_dbconnect) or trigger_error(mysql_error(),E_USER_ERROR);
?>
<?php
$query = "SELECT * FROM tbl_emp_sched";
$result = mysql_query($query) or die ("no query");
$row_try=mysql_fetch_array($result);
$numrows=mysql_num_rows($result);
/*
$empid=unserialize($row_try['Employee_ID']);
$empname=unserialize($row_try['Emp_FullName']);
$empwrk=unserialize($row_try['Emp_WrkFrcCode']);
$empsch=unserialize($row_try['Emp_SchdCode']);
$datas= array(
"0" => $empid,
"1" => $empname,
"2" => $empwrk,
"3" => $empsch
);
print_r ($datas);
*/
$array_try = array($result['Employee_ID'],$result['Emp_FullName'],$result['Emp_WrkFrcCode'],$result['Emp_SchdCode']);
while($datas = mysql_fetch_array($result))
{
$array_try[] = $datas;
}
function cleanData(&$str)
{
$str = preg_replace("/\t/", "\\t", $str);
$str = preg_replace("/\r?\n/", "\\n", $str);
if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"';
}
$filename = "Rota_Schedule_(Schedule Codes)" . date('Ymd') . ".xls";
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
$flag = false;
foreach($array_try as $datas) {
if(!$flag) {
echo implode("\t", array_keys($datas)) . "\n";
$flag = true;
}
array_walk($datas, 'cleanData');
echo implode("\t", array_values($datas)) . "\n";
}
?>
but i don't get what i want. Anybody can help me? This problem causing me hours and hours of testing, any other idea? I tried to unserialize it first but the code just gone crazy and not working properly. Anybody can help me? Thanks
