IF Resource Evaluation test

test.php

<?php

	if ( $ch = curl_init() && curl_setopt($ch,CURLOPT_AUTOREFERER,FALSE) ) {
		echo "Passed this test.\r\n";
	}
	else {
		echo "Failed this test.\r\n";
	}

	class moo {
		function test() {
			if ($this->ch = curl_init() && curl_setopt($this->ch,CURLOPT_AUTOREFERER,FALSE) ) {
				echo "Passed this test.\r\n";
			}
			else {
				echo "Failed this test.\r\n";
			}
		}
	}

	$Moo = new moo();
	$Moo->test();
	
	?>
	
	All of these tests above fail with the erorr, that there is no valid resource on $ch available to setopt functions. 
	
	With that in mind, switching it to OR, in the form of:
	
	<?php
	
	
	if ( $ch = curl_init() 
|| curl_setopt($ch,CURLOPT_AUTOREFERER,FALSE) ) {
		echo "Passed this test.\r\n";
	}
	else {
		echo "Failed this test.\r\n";
	}


?>

Passes the test.

As an aside, wrapping the call inside another bracket works:

    if ( ($ch = curl_init() )
&& curl_setopt($ch,CURLOPT_AUTOREFERER,FALSE) ) {
        echo "Passed this test.\r\n";
    }
    else {
        echo "Failed this test.\r\n";
    }
