At it says
"As of PHP 7.0.0 E_WARNING is emitted in this case and "\e" modifier has no effect."

This implies that the results of the function should be the same whether or not the /e modifier is present.  But the actual result is that preg_replace returns null if the modifier is there regardless of the RE or the target string.

I have no particular problem with the behavior, but the documentation should reflect it.

Test script:
$x = "1 2 3 a b c 4";

$y = preg_replace("#\d#e", 'X', $x));
$z = preg_replace("#\d#", 'X', $x));

//documentation implies that $y == $z

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
