String and variable to output variable

My intention is to output $car1, $car2 to have a list in the HTML output e.g Toyota, BMW, ...However i am getting $car2 in the HTM开发者_运维问答L output. How does one make the loop output $car1, $car2... Is there another function other than echo to do this?

for ($i = 1; $i <= 10; $i++) {
    echo $car . $i;
    echo "<br>";
}

You're looking for variable variables:

for ($i = 1; $i <= 10; $i++) {
   $varName = "car" . $i;
   echo $$varName . "<br />";
}

or, for short:

for ($i = 1; $i <= 10; $i++) {
   echo ${'car' . $i} . "<br />";
}

You'd be better off with arrays, though.

I'm guessing:

You have a bunch of variables called:

• $car1
• $car2
• $car3
• $car4
• ...

And now you want to output them using this:

echo $car . $i;

So you want the code the generate $car1 for you?

This won't work. You shouldn't do this. You should use an array to save your cars. This can be looped over using a for or foreach-loop.

As Tomalak mentioned, arrays should be used in this case.

$car[] = "Honda";
$car[] = "Toyota";
$car[] = "Dodge";
$car[] = "Ford";

for($i = 0; $i<=3; $i++){
  echo $car[$i];
  echo "<br>";
}

Output:

Honda
Toyota
Dodge
Ford
