PHP - for loops through associative array

Question

I have an associative array $_POST, which has 3 key value pairs (There are other key value pairs which I am not interested in).

$_POST[Var1]
$_POST[Var2]
$_POST[Var3]

How do I use a for loop to loop through and echo the values in each?

for ($i = 1; $i <= 3; $i++){
    echo $_POST['Var' . '$i']; 
}

This does not seem to work.

Get rid of the single quotes around $i as that makes it a literal string and your variable is not interpolated:

for ($i = 1; $i <= 3; $i++){
    echo $_POST['Var' . $i]; 
}

This is basic PHP. I strongly recommend reading the manual to learn more about the fundamentals of PHP.

Check this. While using php varibles dont put upper commas for the variables.

  <?php
    $_POST["file1"];
    $_POST["file2"];
    $_POST["file3"];
    for ($i = 1; $i <= 3; $i++){
        echo $_POST['file'.$i]; 
    }

Or this way:

$_POST["Var{$i}"];
