Sprintf format placeholders parser
==================================

[](#sprintf-format-placeholders-parser)

PHP-based parser class that can be used to find all format placeholders of the [sprintf](https://www.php.net/manual/en/function.sprintf.php) function in a string, and get information on them.

Requirements
------------

[](#requirements)

- PHP >= 7.4

Installation
------------

[](#installation)

Simply require the package via composer:

```
composer require php-sprintf-parser

```

Or add it to your `composer.json` manually:

```
{
  "require":{
    "mistralys/php-sprintf-parser": "^1.0"
  }
}
```

Usage
-----

[](#usage)

### Parse texts with several placeholders

[](#parse-texts-with-several-placeholders)

Finding all formatting placeholders in a given string can be done with the `parseString()` function.

```
use function Mistralys\SprintfParser\Functions\parseString;

$parser = parseString('The price of product %1$s has been set to %2$.2d EUR.');

$placeholders = $parser->getPlaceholders();
```

Each placeholder instance can then be used to access all relevant information on the placeholder's configuration, like its number (if any), precision, width, etc.

### Parse individual formatting strings

[](#parse-individual-formatting-strings)

Single placeholder format strings can also be parsed to retrieve information on the placeholder directly.

```
use function Mistralys\SprintfParser\Functions\parseFormat;

$placeholder = parseFormat('%1$.2d');
```

### Access placeholder information

[](#access-placeholder-information)

A placeholder gives access to all individual components of a format string. As the official PHP documentation for [sprintf](https://www.php.net/manual/en/function.sprintf.php)states, the format prototype looks like this:

```
%[argnum$][flags][width][.precision]specifier

```

The placeholder class allows easy access to each of these components. The following is a valid format for example, which uses all possible options.

```
use function Mistralys\SprintfParser\Functions\parseFormat;

$placeholder = parseFormat("%1$+-0'*4.3d");

$placeholder->getSpecifier(); // s
$placeholder->getNumber(); // 1
$placeholder->getWidth(); // 4
$placeholder->getPrecision(); // 3
$placeholder->getPaddingChar(); // *
$placeholder->hasPlusMinusPrefix(); // true
$placeholder->hasLeftJustification(); // true
$placeholder->hasOnlyZeroLeftPadding(); // true
```
