Respect\StringFormatter

A powerful and flexible PHP library for formatting and transforming strings.

Installation

composer require respect/string-formatter

Usage

You can use individual formatters directly or chain multiple formatters together using the FormatterBuilder:

echo f::create()
    ->mask('7-12')
    ->pattern('#### #### #### ####')
    ->format('1234123412341234');
// Output: 1234 12** **** 1234

Using Formatters as Modifiers

The PlaceholderFormatter allows you to use any formatter as a modifier within templates:

use Respect\StringFormatter\PlaceholderFormatter;

$formatter = new PlaceholderFormatter([
    'date' => '2024-01-15',
    'amount' => '1234.56',
    'phone' => '1234567890',
]);

echo $formatter->format('Date: {{date|date:Y/m/d}}, Amount: ${{amount|number:2}}, Phone: {{phone|pattern:(###) ###-####}}');
// Output: Date: 2024/01/15, Amount: $1,234.56, Phone: (123) 456-7890

See the PlaceholderFormatter documentation and FormatterModifier documentation for more details.
