Answer 1

Once you return in the for loop the for loop is exited and no further iterations of the loop occur.

You could do something like this:

<?php
$abc = "abcdef";
function solo()
{
global $abc;
for($k=0;$k<3;$k++)
{
print $abc[$k];
}
}
echo solo();
?>

Or this:

<?php
$abc = "abcdef";
function solo()
{
global $abc;
$str = "";
for($k=0;$k<3;$k++)
{
$str .= $abc[$k];
}
return $str;
}
echo solo();
?>

Answer 2

when a function reaches a return statement it exits, so in your case it enters the loop and exits returning the first char in the string, which is "a".

Answer 3

Return is like a one-way line.
It kinda is the break keyword of loops.
To make it better replace return with echo.
And remove that echo when you call it.

Answer 4

You could using the second version in my post. Just save the returned string in the file.

Answer 5

Then you modify the code to add the <br> either in the function or where you're saving to the file or however else you see fit that does what you're looking for.

Answer 6

Answer 7
