Subject: [RFC]strn(case)cmp supporting negative length as third parameter
From: laruence@php.net (Laruence)

Hi:

  strn(case)cmp dosen't  support a negative length as its third
paramter,  while substr dose.

 I wrote a patch to make strn(case)cmp supporting negative length,
make following script works as expect:

    <?php
   if (strncmp("prefix_num", "num", -3) =3D=3D=3D 0) {
        echo "they have same suffix\n";
   }
  ?>

 here is the rfc: https://wiki.php.net/rfc/strncmpnegativelen

 any question? plz worte me back.

 thanks
