Is it possible to simply this code...
echo $object->property1;
echo $object->property2;
echo $object->property3;
... with something like this, with eval ?
for ($i=0; $i<10; $i++)
echo eval("$object->property".$i);
Thanks.

Why do you need eval() here, using eval() just to reduce 3 lines of code to 2 lines of code at a significant cost in readability, performance overhead and the risk of being eaten by a giant cockroach?Mark Baker– Mark Baker2013-05-23 09:37:35 +00:00Commented May 23, 2013 at 9:37

I simplified a lot here, but i've got a loooooooot of code to do for each property[number], and i'd like to put this code in a for loop, to avoid repetitions.Alarid– Alarid2013-05-23 09:39:20 +00:00Commented May 23, 2013 at 9:39

You can create the property name dynamically without using eval():
$object = new stdClass();
$object->property1 = 10;
$object->property2 = 20;
$object->property3 = 30;
for ($i=1; $i<4; $i++)
echo $object->{"property".$i};

well $object would be out of scope in the eval function. you would need to define the object within the eval string.

Can't you do something like this :
for ($i=0; $i<10; $i++)
{
$tmp = "$object->property".$i
echo $$tmp;
}
I'm not sure if dynamic variables are applied that way in OOPhP, I see the downvotes coming :-)
