You can try this

This might help, but relies on PHP 5.3 or newer.

Not sure you can do this, can you? curl progress is one thing (with callback function), but with a progress bar?

Hi..

Thanks for your reply.
I used following code.
Its working well but it displaying the message "please wait..." repeatedly on the screen.
Is there any way to show the message only once when download progress.

<?php



  $url  = 'http://192.168.1.40/example/example.pdf';
  $path = 'example.pdf';
    $fp = fopen($path, 'w');






$ch = curl_init( $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt( $ch, CURLOPT_NOPROGRESS, false );

curl_setopt( $ch, CURLOPT_PROGRESSFUNCTION, 'progressCallback' );

curl_setopt( $ch, CURLOPT_FILE,  $fp );

curl_exec( $ch );
fclose($fp);



function progressCallback( $download_size, $downloaded_size, $upload_size, $uploaded_size )

{

echo "please wait...";
static $previousProgress = 0;

if ( $download_size == 0 )

$progress = 0;

else

$progress = round( $downloaded_size * 100 / $download_size );

if ( $progress > $previousProgress)

{


$previousProgress = $progress;

$fp = fopen( "example.pdf", 'a' );

fputs( $fp, "$progress\n" );

fclose( $fp );

}


}
echo "<script>window.location='completion.php'</script>";


?>

I think you can try to used if statement.

if ($progress){ 

echo "please wait...";

}else{

...

}
