I am using ob_start()/ob_flush() to, hopefully, give me some progress during a long import operation.
Here is a simple outline of what I'm doing:
<?php
ob_start ();
echo "Connecting to download Inventory file.<br>";
$conn = ftp_connect($ftp_site) or die("Could not connect");
echo "Logging into site download Inventory file.<br>";
ftp_login($conn,$ftp_username,$ftp_password) or die("Bad login credentials for ". $ftp_site);
echo "Changing directory on download Inventory file.<br>";
ftp_chdir($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."<br>";
ob_flush();
flush();
sleep(5);
if (ftp_get($conn,$localname,"INV.csv",FTP_ASCII))
{
echo "New Inventory File Downloaded<br>";
$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 <= $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();
However, nothing is being output to the screen at all.
I know the data file is getting downloaded because I watch the directory where it is being placed.
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.
Any ideas as to why I am not getting output to the screen?
