    <p>I am using <code>ob_start()</code>/<code>ob_flush()</code> to, hopefully, give me some progress during a long import operation.</p> <p>Here is a simple outline of what I'm doing:</p> <pre><code>&lt;?php ob_start (); echo "Connecting to download Inventory file.&lt;br&gt;"; $conn = ftp_connect($ftp_site) or die("Could not connect"); echo "Logging into site download Inventory file.&lt;br&gt;"; ftp_login($conn,$ftp_username,$ftp_password) or die("Bad login credentials for ". $ftp_site); echo "Changing directory on download Inventory file.&lt;br&gt;"; ftp_chdir($conn,"INV") or die("could not change directory to INV"); // connection, local, remote, type, resume $localname = "INV"."_".date("m")."_".date('d').".csv"; echo "Downloading Inventory file to:".$localname."&lt;br&gt;"; ob_flush(); flush(); sleep(5); if (ftp_get($conn,$localname,"INV.csv",FTP_ASCII)) { echo "New Inventory File Downloaded&lt;br&gt;"; $datapath = $localname; ftp_close($conn); } else { ftp_close($conn); die("There was a problem downloading the Inventory file."); } ob_flush(); flush(); sleep(5); $csvfile = fopen($datapath, "r"); // open csv file $x = 1; // skip the header line $line = fgetcsv($csvfile); $y = (feof($csvfile) ? 2 : 5); while ((!$debug) ? (!feof($csvfile)) : $x &lt;= $y) { $x++; $line = fgetcsv($csvfile); // do a lot of import stuff here with $line ob_flush(); flush(); sleep(1); } fclose($csvfile); // important: close the file ob_end_clean(); </code></pre> <p>However, nothing is being output to the screen at all.</p> <p>I know the data file is getting downloaded because I watch the directory where it is being placed.</p> <p>I also know that the import is happening, meaning that it is in the while loop, because I can monitor the DB and records are being inserted.</p> <p>Any ideas as to why I am not getting output to the screen?</p>

    1. COWhy are you using output buffering if you specifically *don't* want to buffer output and send it as the page is being processed?

    2. COWhat do you mean? I DO want to output the stuff as it is being processed. Isn't that what I said?

    3. COOutput buffering is for doing exactly the opposite, that is, buffering the output and sending it all at once. Why are you using it?

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.
