<?php
echo "Hello World!";
__halt_compiler();build.php
<?php
$phar = new Phar('output.phar');
$phar->startBuffering();
$phar->setStub(file_get_contents('stub.php'));
$phar->addEmptyDir('src');
$phar->stopBuffering();Resulted in this output:

But when I write __HALT_COMPILER in UPPER case it works always. I normally write it always upper-case but saw in docs other mentioned, just copy pasted. https://www.php.net/manual/en/function.halt-compiler.php
it looks like it's hard-code to upper-case:
Line 1230 in e97c0dc
Are the docs just wrong, should this be changed in php idk 😂 . The execution of the phar works with regardless of caseing
