public static void showCursor ( ) |
Starts display of a progress bar on screen.
This bar will be updated by updateProgress() and my be ended by endProgress().
The following example shows a simple usage of a progress bar:
Console::startProgress(0, 1000);
for ($n = 1; $n <= 1000; $n++) {
usleep(1000);
Console::updateProgress($n, 1000);
}
Console::endProgress();
Git clone like progress (showing only status information):
`
php
Console::startProgress(0, 1000, 'Counting objects: ', false);
for ($n = 1; $n <= 1000; $n++) {
usleep(1000);
Console::updateProgress($n, 1000);
}
Console::endProgress("done." . PHP_EOL);

This can be an integer representing the number of characters to display for the progress bar or a float between 0 and 1 representing the percentage of screen with the progress bar may take. It can also be set to false to disable the bar and only show progress information like percent, number of items and ETA. If not set, the bar will be as wide as the screen. Screen size will be detected using getScreenSize(). |
Prints a string to STDERR.
public static integer|boolean stderr ( $string ) | ||

will result in the
following output, given the screen width is 16 characters:
Lorem ipsum
dolor sit
amet.
