Follow up on export mysql to csv: Per David Hagood's suggestion to check out AI, this is solved. It's not perfect yet as I haven't figured out how to have a page to show client interface but a link to the page does do the download correctly. I am guessing I can fix with enough fiddling.
Thanks David!
Using CHAT 3.5, I asked: Write website interface to download a mysql file to csv using php
<?php
// MySQL database connection parameters
$host = 'localhost';
$username = 'user';
$password = 'password';
$database = 'database';
// Connect to MySQL database
$mysqli = new mysqli($host, $username, $password, $database);
// Check connection
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: " . $mysqli->connect_error;
exit();
}
// SQL query to fetch data
$sql = "SELECT * table name";
// Execute query
$result = $mysqli->query($sql);
if (!$result) {
echo "Error: " . $mysqli->error;
exit();
}
// Create a file pointer
$fp = fopen('export.csv', 'w');
// Write column headers to CSV
$fields = $result->fetch_fields();
$column_headers = [];
foreach ($fields as $field) {
$column_headers[] = $field->name;
}
fputcsv($fp, $column_headers);
// Write data rows to CSV
while ($row = $result->fetch_assoc()) {
fputcsv($fp, $row);
}
// Close file pointer
fclose($fp);
// Free result set
$result->free();
// Close MySQL connection
$mysqli->close();
// Set headers for CSV file download
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="export.csv"');
header('Pragma: no-cache');
readfile('export.csv');
exit();
?>
HTML (doesn't get called into play)
<body>
Export
<form method="post" action="">
<input type="submit" name="export" value="Export to CSV">
</form>
</body>
