<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>In TypedInputsTrait.php, we have this syntax...</p>
<pre>const string STORAGE_CONFIGURATION = 'config';<br>const string STORAGE_INPUT = 'input';<br>const string INPUT_SOURCE_INPUT = 'input';<br>const string INPUT_SOURCE_CONFIG = 'config';<br>const string INPUT_SOURCE_LOCKED = 'locked';<br>const string INPUT_SOURCE_DEFAULT = 'default';</pre><p>This syntax is not available in PHP 8.2, even though the Tool module asks for PHP >=8.2.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>1. Use PHP 8.2<br>
2. Check syntax for TypedInputsTrait.php<br>
3. See the following exception...</p>
<blockquote><p>
PHP Fatal error: During class fetch: Uncaught ParseError: syntax error, unexpected identifier "STORAGE_CONFIGURATION", expected "=" in TypedInputsTrait.php:27
</p></blockquote>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Don't use const string, but just const. Alternatively, we could target PHP 8.3, but that would require a major version release.</p>
<h3 id="summary-remaining-tasks">Remaining tasks</h3>
<p>Fix it.</p>

<p>It's a const instead of a const string.</p>
