    <p>I am having some trouble exporting a CSV file using fputcsv. The file downloads but it is blank. I have tried exporting to xls and it works perfectly but I wanted to use csv with custom field headers as shown in code below. I am not sure if I am doing something wrong or if I need to have any php.ini changes done. I know I have fopen enabled but the file is about 6.5mb of database information.</p> <p>Thanks in advance!</p> <pre><code>$colnames = array( 'forDepts' =&gt; "Member No.", 'clientId' =&gt; "Date joined", 'createdOn' =&gt; "Title", 'createdBy' =&gt; "First name", 'description' =&gt; "Notes" ); function map_colnames($input) { global $colnames; return isset($colnames[$input]) ? $colnames[$input] : $input; } function cleanData(&amp;$str) { if($str == 't') $str = 'TRUE'; if($str == 'f') $str = 'FALSE'; if(preg_match("/^0/", $str) || preg_match("/^\+?\d{8,}$/", $str) || preg_match("/^\d{4}.\d{1,2}.\d{1,2}/", $str)) { $str = "'$str"; } if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"'; $str = mb_convert_encoding($str, 'UTF-16LE', 'UTF-8'); } // filename for download $filename = "website_data_" . date('Ymd') . ".csv"; header("Content-Disposition: attachment; filename=\"$filename\""); header("Content-Type: text/csv; charset=UTF-16LE"); $out = fopen("php://output", 'w'); $flag = false; $result = mysql_query("SELECT forDepts, clientId, createdOn, createdBy, description FROM notes") or die('Query failed!'); while(false !== ($row = mysql_fetch_assoc($result))) { if(!$flag) { // display field/column names as first row fputcsv($out, array_keys($row), ',', '"'); $flag = true; } array_walk($row, 'cleanData'); fputcsv($out, array_values($row), ',', '"'); } fclose($out); exit; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
