Repeat Strings Efficiently with Laravel's Str::repeat Method

Laravel's Str::repeat method offers a simple solution for creating repeated string patterns by duplicating a string a specified number of times.

Repeat a string a specific number of times:

use Illuminate\Support\Str;
 
$character = 'x';
$repeated = Str::repeat($character, 4);
// Result: 'xxxx'

Here's how you might use it in a report formatter:

class ReportFormatter
{
    public function createSeparatorLine(int $length = 50)
    {
        return sprintf(
            '%s%s%s',
            '+',
            Str::repeat('-', $length - 2),
            '+'
        );
    }
 
    public function formatProgressBar(int $completed, int $total = 10)
    {
        $progress = Str::repeat('█', $completed);
        $remaining = Str::repeat('░', $total - $completed);
 
        return sprintf(
            '[%s%s] %d%%',
            $progress,
            $remaining,
            ($completed / $total) * 100
        );
    }
 
    public function createIndentation(int $level)
    {
        return sprintf(
            '%s%s',
            Str::repeat('  ', $level),
            '- '
        );
    }
}
 
$formatter = new ReportFormatter();
 
echo $formatter->createSeparatorLine(30);
// Output: +----------------------------+
 
echo $formatter->formatProgressBar(7);
// Output: [███████░░░] 70%
 
echo $formatter->createIndentation(3);
// Output:       -

The repeat method provides a clean way to handle string repetition tasks in your Laravel applications.
