1.2.464. Flexible Heredoc¶
Flexible syntax for Heredoc.
The new flexible syntax for heredoc and nowdoc enable the closing marker to be indented, and remove the new line requirement after the closing marker.
It was introduced in PHP 7.3. This syntax is backward incompatible : once adopted in the code, previous versions won’t compile it.
<?php
// PHP 7.3 and newer
foo($a = <<<END
flexible syntax
with extra indentation
END);
// All PHP versions
$a = <<<END
Normal syntax
END;
?>
