Export MySQL Data to Excel in PHP

Troubleshooting Cell Alignment Issues

If your MySQL data is not aligning correctly in Excel cells, where multiple rows of data end up in a single cell, here's how to resolve this issue:

Solution:

The provided PHP script requires a few modifications to handle multiple rows correctly. Here's the revised code:

<?php
// Database connection details
$DB_Server = "localhost";
$DB_Username = "username";
$DB_Password = "password";
$DB_DBName = "databasename";
$DB_TBLName = "tablename";
$filename = "exportfile"; // File name

// Create MySQL connection
$Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect to MySQL: " . mysql_error() . "<br>" . mysql_errno());

// Select database
$Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database: " . mysql_error() . "<br>" . mysql_errno());

// Execute query
$sql = "SELECT username, password, fullname FROM ecustomer_users WHERE fk_customer='$fk_customer'";
$result = @mysql_query($sql, $Connect) or die("Couldn't execute query: " . mysql_error() . "<br>" . mysql_errno());

// Header info for browser
header("Content-Type: application/xls");
header("Content-Disposition: attachment; filename=$filename.xls");
header("Pragma: no-cache");
header("Expires: 0");

// Start formatting for Excel
$sep = "\t"; // Tabbed character

// Print column names
for ($i = 0; $i < mysql_num_fields($result); $i++) {
    echo mysql_field_name($result, $i) . $sep;
}
echo "\n";

// Start while loop to get data
while ($row = mysql_fetch_row($result)) {
    $schema_insert = "";
    for ($j = 0; $j < mysql_num_fields($result); $j++) {
        if (!isset($row[$j])) {
            $schema_insert .= "NULL" . $sep;
        } elseif ($row[$j] != "") {
            $schema_insert .= "$row[$j]" . $sep;
        } else {
            $schema_insert .= "" . $sep;
        }
    }
    $schema_insert = str_replace($sep . "$", "", $schema_insert);
    $schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert);
    $schema_insert .= "\t";
    print(trim($schema_insert));
    print "\n";
}
mysql_close($Connect);
