I'm new here on the list... Hello everyone!
I use ::class sometimes to check some classes, but it works with any keyword, even if the class doesn't exist.
The IDE doesn't show the error, and I only detect the error when the specific piece of code is running...
<?php
echo foo::class;
Hey Fabio,
I'm new here on the list... Hello everyone!
I use ::class sometimes to check some classes, but it works with any
keyword, even if the class doesn't exist.
The IDE doesn't show the error, and I only detect the error when the
specific piece of code is running...<?php
echo foo::class;
::class is effectively replaced with a string at compile time:
Finding entry points
Branch analysis from position: 0
1 jumps found. (Code = 62) Position 1 = -2
filename: /in/8lL10
function name: (null)
number of ops: 2
compiled vars: none
line #* E I O op fetch ext
return operands
2 0 E > ECHO
'foo'
3 1 > RETURN 1
This is by design, since otherwise each ::class lookup would result in
autoloading, which would be disastrous for large maps of classes (like in
service containers).
