I'm not keen on adding lots of multi-line if statements - I prefer tp
put things into arrays where I can. Easier to update them.
<?php
function foo($p)
{
$foodefault = array( // prefix matching the name in 'extract'
'foo_fred'=> '<strong>default fred</strong>',
'foo_banana' => '<strong>default bananananana</strong>',
);
extract ($p, EXTR_PREFIX_ALL, 'foo'); // get params
extract ($foodefault, EXTR_SKIP, "foo"); // get defaults
echo "$foo_fred / $foo_banana";
}
echo "Both in place: ";
foo(array('fred' => 'hello', 'banana' => 'world'));
echo "<br /> Now with a missing param: ";
foo(array('fred' => 'hello'));
echo "<br /> Now both missing params: ";
foo(array());
?>
