ForEach

public function forEach(
    callable $action,
    ?ExpressionPattern $pattern = null
): Text

forEach loops over expressions found in the text. forEach can only read, not write. You can extract information about the expressions, such as their signature, arguments and output.

If you want to change the expression in the text, you can use map or rebase.

Example

This example will catch p:name() and amount:(order.amount).

$text = new Text('Hello p:name(). You owe us amount:(order.amount)');

$text->forEach(function($fragment) {
    var_dump($fragment);
});
