<?php
$start = 1;
$times = 2;
$answer = array();
for ($start; $start < 11; $start++) {
    $answer[$start] = $start * $times;

// print $answer; // will print "Array" and/or give an "Array to string conversion" error,
// because $answer is an array (which is not something you can print).

// do this instead:
print $answer[$start];

// if you expect each number to be on its own line, 
// you also need to do
print "\n";

// and/or (if you're outputting HTML)
print '<br>';
}

tested.

* note, you don't get a "22" line because your loop only runs while [font=monospace]$start[/font] is less than eleven. You can do [font=monospace]$start <= 11[/font] if you want to change that.

if you really wanted to end up with 4 ... 22, don't increment in the for() construct - increment before you multiply instead.
IF that's what you want. Seems a potential source of confusion/bugs to me. But whatever. [noparse]🙂[/noparse]

<?php
$start = 1;
$times = 2;
$answer = array();
for ($start; $start < 11; ) {
    $start++;
    $answer[$start] = $start * $times;
    print $answer[$start]."<br>";
}

you're welcome

<?php
$start = 1;
$times = 2;
$answer = array();
for ($start; $start < 11; ) {
$start++;
$answer[$start] = $start * $times;
print $answer[$start]."<br>";
}

That a bit confusing to me........ I have read that for loop have three part "for (start value; end value; update expression) {Statement here}"
But you just write start value and end value and write the increment part in the statement section then how statement is executing by loop......the loop should not run at all. I am beginner please clear it to me.

The third part is just empty. In fact, all three parts could be empty, as long as the semi-colons are present.
