Escape Character

Escape characters are special characters, that introduce a special meaning, for example when redacting an escape sequence.

Escape characters are often generating a special sequence to escape themselves and allow their literal meaning to be expressed.

In strings and HEREDOC, the escape character is the backslash: \.

<?php

    echo '<a href="https://www.exakat.io/" />';

    // This prevents the variable $x to be interpolated
    echo <<<HEREDOC
    echo $x;
HEREDOC;

?>
