I wont try to justify PHP hacking but I was working on a project that's based on CodeIgniter. It's on a cycle of heavy refactoring. I was wondering if I could do something like
isset("variable_name");
similar to python
"variable_name" in globals()
Same idea with locals() in python.
Thankfully, php has the equivalent of globals() being $GLOBALS which would return you all the variables declared so far. Now you can just write your own isset_varname(). get_defined_vars() is equivalent in php to locals(). in python.
<?php
function isset_varname($varname){
return array_key_exists($varname, $GLOBALS);
}
$test= "test";
var_dump(isset_varname("test")); // should print bool(true)
var_dump(isset_varname("test2")); // should print bool(false)
?>
you'd probably need to check for the variable name regex and store output from get_defined_vars() in another place too. Of course, if there's some other similar function that anyone else knows about, I'd be happy to find out.
