How to set a variable separator

I have a variable $cameramodel which contains term meta of a wordpress taxonomy:

$cameramodel

<?php
function cameramodel() {
$terms = get_the_terms($post->ID, 'camera');
$result = "";
foreach ($terms as $term) {
$term_id = $term->term_id;
$result .= get_term_meta( $term_id, 'model', true );
}
return $result;
}

$cameramodel = cameramodel(); ?>


On the front end I would echo $cameramodel

$cameramodel

<?php echo $cameramodel; ?>


There are instances where $cameramodel contains more than one value, but when I echo $cameramodel, They all appear on one line with no spaces. My question is, how do I make a separator between each value? I want each value to be on it's own line, and I would like to be able to separate them with the word "and".

$cameramodel

$cameramodel

For example, if the variable contains "one two three" it currently prints "onetwothree", but what I want is:

one and
two and
three


Hope I am being clear.

Thanks!

If the values are stored one on each line, you could just use trim(), which removes whitespace characters (including new lines) from before and after the strings:

trim()

$result .= ' ' . trim(get_term_meta( $term_id, 'model', true ));


Change the ' ' to use the separator of your choice. Note that this will also add this to the beginning of the string. If this is a problem, you could then ltrim() the result when you return it.

' '

ltrim()

return

Assuming you are printing to an HTML document, you could try this:

$cameramodel = "one two three";
echo preg_replace('/s+/', ' and<br>', $cameramodel);


Output:

one and
two and
three


If it's not HTML, just replace <br> with n (or rn if required).

<br>

n

rn

If you are willing to edit the function slightly, I believe you will benefit from using an array and then joining it together into a string with the delimiter of your choice passed as an argument:

<?php
function cameramodel($delimiter) {
# Get the terms.
$terms = get_the_terms($post->ID, 'camera');

# Create an array to store the results.
$result = ;

# Iterate over every term.
foreach ($terms as $term) {
# Cache the term's id.
$term_id = $term->term_id;

# Insert the term meta into the result array.
$result = get_term_meta($term_id, 'model', true);
}

# Return the elements of the array glued together as a string.
return implode($delimiter, $result);
}

# Call the function using a demiliter of your choice.
$cameramodel = cameramodel("and<br>");
?>
