      <pre class=3D"moz-quote-pre" wrap=3D"">Hello internals,

It is this time of year again where we proposed a list of deprecations to=
 add in PHP 8.4:

<a class=3D"moz-txt-link-freetext" href=3D"https://wiki.php.net/rfc/depre=
cations_php_8_4">https://wiki.php.net/rfc/deprecations_php_8_4</a>

As a reminder, this list has been compiled over the course of the past ye=
ar by various different people.

And as usual, each deprecation will be voted in isolation.

We still have a bit of time buffer, so if anyone else has any suggestions=
, they are free to add them to the RFC.

Some should be non-controversial, others a bit more.
If such, they might warrant their own dedicated RFC, or be dropped from t=
he proposal altogether.</pre>
    </blockquote>
    <p>I would like to propose a deprecation of implicit cast to int of
      numeric strings using bit shift operators.<br>
    </p>
    <p>For the following reasons:<br>
      1. In PHP strings are byte arrays and without context it's not
      possible to know if "123" is actually a number or just three bytes
      of 0x313234<br>
      2. The other bitwise operators `|`, `&amp;`, `~`, `^` already take
      it as byte array, only the bit shift operators try to be smart
      here<br>
      3. Non numeric strings already fail with "Unsupported operand
      types: string &gt;&gt; int"<br>
      4. This makes working with byte arrays unnecessary hard and forces
      you to use limited and system depending int's.</p>
    <p><a class=3D"moz-txt-link-freetext" href=3D"https://3v4l.org/IBUDD"=
>https://3v4l.org/IBUDD</a><br>
    </p>
    <p>While processing strings as byte arrays using bit shift operators
      needs a separate RFC, I think, if there is an agreement on
      deprecating this implicit cast it would already be beneficial to
      have this sooner than later.</p>
    <p>What do you think?<br>
    </p>
