Prevent php from removing trailing zeros

[admien]

Let's say I want to construct some input fields using this for each loop :

foreach($_POST['test3'] as $key => $test3key){
    $test3 = $test3key;
    $test31 = $_POST['test31'][$key];
    $test32 = $_POST['test32'][$key];
    if (!empty($test3key) && !empty($test31) && !empty($test32)) {
// insert sql


}
}

The data for example is test3 = 0033, test31 = 1; test32 is 1,000

In this particular case, the test3 will get converted to just 33 in the database table column. The test3 column type in the database is text. I want to prevent the leading zero removal. How can I accomplish this?

Use sprintf. You can convert the number to whatever format you want to enforce.

$test3 = sprintf('%04d',$test3key);
