[ADVANCED] invoke function with variable

[Anon]

Hi,
I have a few functions that draw something in HTML. Those function have different number of argument (some have 2, some have 3 or more).
I want to write a function that wrap take one of the the previous function and wrap a table around it. Something like :

function wrapper ($title, $func, $arg1, arg2) {
echo "<table><tr><td>$title</td></tr><tr><td>";
//now goes the content produce by func
$func($arg1, $arg2);
echo "</td></tr></table>";
}

The problem is how can I pass VARIABLE number of argument to the $func INSIDE the wrapper function ???
Does anyone know how to solve it ?
Maybe there is other way to do the same task ?

I think func_get_arg() may be what u need

function wrapper ($title, $func, $arg1, arg2) {
echo "<table><tr><td>$title</td></tr><tr><td>";
$args="";
for ($i=0;$i<func_num_args;$i++) {
$args.=", \"".func_get_arg($i)."\"";
}
$args=substr($args,1); // discard first comma
eval ("$func ($args)");
echo "</td></tr></table>";
}

there may be a better way to do it (esp. the eval part, but I dunno), and I didn't test so it may be buggy, but it might help...

ow, I already see a mistake in my code :
for ($i=0;$i<func_num_args;$i++) {
should be :
for ($i=0;$i<func_num_args();$i++) {

that's what you get when you don't test it before submitting 🙂
