Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

This is a known false positive raised by valgrind.
 [2019-08-23 05:25 UTC] wang8330 at umn dot edu 
Hi, thanks for your reply. Can you give some detailed information on this false positive? I am pretty curious about what causes this false positive in PHP and Valgrind. Thanks.

Hi, can you provide some information on this Valgrind false positive? I tried to search online but I didn't get any related information.
 [2019-08-26 08:57 UTC] nikic@php.net 
@wang8330: See https://github.com/php/php-src/blob/4c70a585b73ca336b102ec20f88ee9e782c5919e/Zend/zend_string.c#L327 and following. String comparisons intentionally branch on uninitialized bytes, but in a way that is safe.

You can build PHP with valgrind support to avoid these warnings. Generally valgrind will be automatically picked up if it is present at build time. You can force it using --with-valgrind.
