Note Submitter: ian at iyates dot com ---- In response to LexZEUS: If you used the same code with | instead of || and & instead of && (as follows) function lex1() { print "Hello"; return 1; } function lex2() { print "World"; return 1; } if (lex1() | lex2()) {} if ( @function1() & @function2() & @function3() & @function4() & @function5()) {} All functions would be executed before the final boolean is returned. Although || and && are more useful (efficient and easy to understand), | and & are normally used when some functions _have_ to be executed even if one fails. a good example is: if (isset($a) && $a == 'hello') echo $a; if (isset($b) & $b == 'world') echo $b; while the first 'if' will always be okay, the second will return an error if $b had not been set as it will still compare $b to 'world' (which should return 'false' and a warning)
