i have:
echo $test->getNum1();
echo $test->getNum2();
echo $test->getNum9();
how can i make something:
for(i=0;i<10;i++){
echo $test->getNum . $i .();
}
?

2The real question here is: Why do you have multiple functions that do the same thing?Tomalak– Tomalak2011-06-05 22:06:46 +00:00Commented Jun 5, 2011 at 22:06

for(i=0;i<10;i++){
$method = 'getNum' . $i;
echo $test->$method();
}

Alexs answer is correct. But the clean way is to create a method
getNum() with an argument. Just sayin' ;)As a complement to Alex's answer, you can also specify a variable name for a function by using call_user_func or call_user_func_array. These take a callback as their first argument, so you can provide a string within this. In this case you could do something like the following:
for($i=0; $i<10; $i++){
$method = array($test, 'getNum' . $i);
echo call_user_func($method);
}

This one will be simplest and most robust (that is if you don't want to write 5 more lines with the reflection api):
for($i=0; $i<10; $i++) {
echo call_user_func(array($test, "getNum{$i}"));
}

for ($i = 0; $i < 10; $i++) {
echo eval('$text->getNum'.$i.'()');
}

eval is evil ;)

There is nothing inherently wrong with this use of
eval, even if it is not the optimal solution. Please check the mindless fearmongering.
