I think function's in bash doesn't accept any variables.
Incorrect, they take parameters just fine.
You call them directly, outside [ ], like you would an external program.
And your function should use return to give an integer value that if can use in this manner. It's like exit but only quits a function or sourced script instead of the entire program. Zero means success, nonzero means failure, just like the exit status of an external utility. Your EC variable trick works but such indirectness isn't necessary.

LEARN ABOUT PHP
exit
EXIT(3) 1 EXIT(3)exit - Output a message and terminate the current scriptSYNOPSIS
void exit ([string $status])
DESCRIPTION
void exit (int $status)
Terminates execution of the script. Shutdown functions and object destructors will always be executed even if exit is called.
exit is a language construct and it can be called without parentheses if no $status is passed.
PARAMETERS
o $status
- If $status is a string, this function prints the $status just before exiting. If $status is an integer, that value will be used
as the exit status and not printed. Exit statuses should be in the range 0 to 254, the exit status 255 is reserved by PHP and
shall not be used. The status 0 is used to terminate the program successfully.
Note
PHP >= 4.2.0 does NOT print the $status if it is an integer.
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
exit example
<?php
$filename = '/path/to/data-file';
$file = fopen($filename, 'r')
or exit("unable to open file ($filename)");
?>
Example #2
exit status example
<?php
//exit program normally
exit;
exit();
exit(0);
//exit with an error code
exit(1);
exit(0376); //octal
?>
Example #3
Shutdown functions and destructors run regardless
<?php
class Foo
{
public function __destruct()
{
echo 'Destruct: ' . __METHOD__ . '()' . PHP_EOL;
}
}
function shutdown()
{
echo 'Shutdown: ' . __FUNCTION__ . '()' . PHP_EOL;
}
$foo = new Foo();
register_shutdown_function('shutdown');
exit();
echo 'This will not be output.';
?>
The above example will output:
Shutdown: shutdown()
Destruct: Foo::__destruct()
NOTES
Note
Because this is a language construct and not a function, it cannot be called using variable functions.
Note
This language construct is equivalent to die(3).
SEE ALSO register_shutdown_function(3).
