Programatically

You can either highlight PHP code in terminal output or export to png image.

Highlight

use Ahc\CliSyntax\Highlighter;

// PHP code
echo new Highlighter('<?php echo "Hello world!";');
// OR
echo (new Highlighter)->highlight('<?php echo "Hello world!";', $options);

// PHP file
echo Highlighter::for('/path/to/file.php', $options);

// $options array is optional and can contain:
[
    'lineNo' => true, // bool
];

Export

use Ahc\CliSyntax\Exporter;

// PHP file
Exporter::for('/path/to/file.php')->export('file.png', $options);

// $options array is optional and can contain:
[
    'lineNo' => true, // bool
    'font'   => 'full/path/of/font.ttf', // str
    'size'   => 'font size', // int
];
