PHP Console Progress Bar

This class creates and maintains progress bars to be printed to the console. This file is a replica of the ezComponents console progress bar class (@link http://ezcomponents.org/docs/api/latest/ConsoleTools/ezcConsoleProgressbar.html) allows a developer to just use the console progress bar features without the rest of the classes saving all the extra files and classes.

Available Options

• barChar: Processed progress bar char (Default ‘=’)
• emptyChar: Empty progress bar char (Default ‘-’)
• formatString: Progress bar formatted line that actually displays the processed number, step count, total count, percentage etc.. (Default ‘%act% / %max% [%bar%] %fraction%%’)
• fractionFormat: Progress bar fraction format (Default ‘%01.2f’)
• progressChar: Progress bar progress leading char (Default ‘>’)
• redrawFrequency: Redraw/Update the progress bar every X step(s) (Default: 1)
• step: Progress bar each advance call will advance X step(s) (Default: 1)
• width: Progress bar width (Default 100)
• actFormat: Progress bar current step format (Default ‘%.0f’)
• maxFormat: Progress bar maximum step format (Default ‘%.0f’)
• max: Progress bar maximum value (When it reaches 100%) (Default 100)


< ?php
require_once('ConsoleProgressBar.php');
// initiate the class with the maximum value being 100
$progress = new ConsoleProgressBar(100);
// Setting options are done using one of the following:
// $progress = new ConsoleProgressBar(100, array('step' => 5, 'barChar' => '+'));
// $progress->setOptions(array('step' => 5, 'barChar' => '+'));
// $progress->setOptions('step', 5);
// $progress->options = array('step' => 5);
// Start the progress bar before the actual actions are taken place
$progress->start();
// This is just an example that's why a simple look is being used
// in real world this can be a db record set process or any other long operation that is being
// done via the cli
for ($i = 0; $i < = 100; $i++) {
// Do the actual processing here
// .....
// .....
// .....
// Advance one step by default
// you can pass a second argument $step which will advance that number of steps
$progress->advance();
// For this example we will just sleep for a second
sleep(1);
}
// Call finish at the end to make sure the bar goes to 100% if it didn't
$progress->finish();
