Description:
------------
Not sure how open you are to feature requests like this.
I use my own function bsprintf() (i.e. boolean sprintf)
quite a bit for display code. What it does is return
$var outputted according to $format *only* if $var is
not empty, otherwise return nothing. If (optional)
$default is passed in, $default is returned instead of
nothing if $var is empty.
function bsprintf($var,$format='%s',$default="") {
if (!empty($var)) {return sprintf($format,$var);}
else if (!empty($default)) return $default;
};
Thought I'd suggest implementing something like this as
a built-in function. Here is a brief example of the type
of use that I've found useful, mostly to keep code
simple, condensed, and readable (especially with long
scripts):
---- USING bsprintf -----
$apples=100;
echo "% Apples: ".bsprintf($apples,'%s%%',"None.")."
/ % Oranges: ".bsprintf($oranges,'%s%%',"None.");
(Total lines: 2)
Returns: % Apples: 100% / % Oranges: None.
---- NOT USING bsprintf -----
$apples=100;
echo "% Apples: ";
echo (!empty($apples)) ? $apples."%" : "None.";
echo " / % Oranges: ";
echo (!empty($oranges)) ? $oranges."%" : "None.";
(OR)
$apples=100;
echo "% Apples: ".((!empty($apples)) ? $apples."%" :
"None.")." / % Oranges: ".((!empty($oranges)) ?
$oranges."%" : "None.");
(Total lines: 5, or 2-- including a really ugly, hard to
read one)
Returns: same as above!
