Question

I know what i have implemented here is wrong i want it to do it correctly that is why asking help here.Don't know whether this is possible or not.

<?php
$test1="hello";
$test2="how";
$test3="are";
for($i=1;$i<=3;$i++)

}
?>

When i run this i should get hello how are .i know string concatenation same thing i want to do it for variable also.Is this Possible, if possible by this i can easily access all those variable. Any help?

Wouldn't array be better? $test[1]='hello';$test[2]='how';$test[3]='are'; foreach($test as $val) { echo $val; } — Ivan Yonkov

Just a question, but why would you like to do this? With all do respect, but this programming logic seems like a rather bad idea to me. If you could provide more framework of what you try to achieve, someone can advise you with code for a better alternative. — Trace

@KimGysen agree with you, seems like a bad OOP, but I've just learnt that it's actually possible to do such thing LOL! — evilReiko

Try with following syntax:

echo ${'test'.$i};

Perfect.can i use more variable like this? @hsz

hsz Over a year ago

If you put it in your loop, $i will change and call next variables. Is it that what did you mean ?

I guess what you're looking for is the "array". You can use arrays in PHP like this:

$test = array('hello', 'how', 'are');
$len = count($test);
for($i=0; $i<$len; $i++) {
   echo $test[$i];
}

Try this:

for($i = 1; $i < 4; $i++){
    echo $test{$i};
}
