Storing a PHP loop as a string in a variable

Question

Hello! I have a problem storing a PHP loop in a variable.

The loop is like this:

for( $i = 1; $i <= 10; $i++ ) {

    echo $i . ' - ';

}

for this it's OK for an echo or print as it will produce:

1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 -

now I want to store the whole loop in a variable like $my_var which means:

echo $my_var;

which will produce:

1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 -

the whole idea is that I want to make the loop, store it as a string in a variable $my_var, than use it later in my script.

I hope the idea is clear. Thanks.

Answer 1

$str = '';

for( $i = 1; $i <= 10; $i++ ) {
    $str .= $i . ' - ';    
}

echo $str;

Simply append the new string to the old one.

Alternatively, you could do

$str = implode(range(1, 10), ' - ') . ' - ';

Or even...

$str = implode(array_merge(range(1, 10), array(' ')), ' - ');
