<literal>$1</literal> backreference, leaving the <literal>1</literal>
as a literal.
</para>
<para>
When using the deprecated <literal>e</literal> modifier, this function escapes
some characters (namely <literal>'</literal>, <literal>"</literal>,
<literal>\</literal> and NULL) in the strings that replace the
backreferences. This is done to ensure that no syntax errors arise
from backreference usage with either single or double quotes (e.g.
<literal>'strlen(\'$1\')+strlen("$2")'</literal>). Make sure you are
aware of PHP's <link linkend="language.types.string">string
syntax</link> to know exactly how the interpreted string will look.
