Command Line Progress Percent Display, no echo

dlite922

I want to display the progress of a job (a cron job) in PHP.

I can do an echo, but the result will look like this:

1%2%3%4%

How do you "backspace" and over-write the percentage with the new value.

I don't know where to begin looking for this. What do you even call this to do a Google search?

I found this:

How can i get that to work in PHP. shell_exec() ?

Just add a \r in front of you output. That should cause the echo to overwrite the previous line.
Like:

Expand|Select|Wrap|Line Numbers

 
<?php

for($i = 0; $i < 100; $i++) {

    echo "\r$i% Completed...";

    usleep(200000);

}

?>

That is assuming you are displaying this in a Linux terminal?
