if statement - php IF OR format? -

this works

if ($flag != 'u') { stuff.. } 

this works.

if ($id != 0) { stuff.. } 

but these don't seem work me....

if ( ($flag != 'u') || ($id != 0) ) { stuff.. } if ( ($flag != 'u') or ($id != 0) ) { stuff.. } if ($flag != 'u') || ($id != 0) { stuff.. } if ($flag != 'u') or ($id != 0) { stuff.. } if ( $flag != 'u' || $id != 0 ) { stuff.. } if ( $flag != 'u' or $id != 0 ) { stuff.. } 

any idea why? , format should use in php?

your code works. tried this

<?php $flag= u; $id= 0; if ( ($flag != 'u') || ($id != 0) )        {            echo "hi";       } ?> 

the code simple says if $flag not equal u or if $id not equals 0 echo hi in page.

is logic?

the problem might in logic hope!
