Question

I am a newbie in Php and this might be a quite basic question.

I would like to set string array and put values to array then get values which

I put to string array. so basically,

I want

ArrayList arr = new ArrayList<String>;
int limitSize = 20;
    for(i = 0; i < limitSize; i++){
          String data = i + "th";
          arr.add(data);
          System.out.println(arr.get(i));
    };

How can I do this in php?

It’s far less verbose in PHP. Since it isn’t strongly typed, you can just append any values onto the array. It can be done with an incremental for loop:

$array = array();
$size = 20;
for ($i = 0; $i < $size; $i++) {
  // Append onto array with []
  $array[] = "{$i}th"; 
}

…or with a foreach and range()

foreach (range(0,$size-1) as $i) {
  // Append onto array with []
  $array[] = "{$i}th";     
}

It is strongly recommended that you read the documentation on PHP arrays.
