Question

Sorry if this is really basic but I am just learning PHP.

I have some code that looks like:

<h4><?=$prop['house_number']?>, <?=$prop['street']?>, <?=$prop['town']?></h4>

That is bring back from the database eg: 55, main street, townname

When the address does not contain a street name it comes back as eg: 55, , townname.

I want to know how to remove the commer so it just brings back eg: 55, townname.

Hopefully it is a really easy one but I have tried a couple of things and cannot seem to get it right.

Many thanks

You could use ternary operators to check if each var is empty. Have a look at http://davidwalsh.name/php-shorthand-if-else-ternary-operators

The code would then look like :

<h4>
<?=!empty($prop['house_number']) ? $prop['house_number'].', ' : ''?>
<?=!empty($prop['street']) ? $prop['street'].', ' : ''?>
<?=!empty($prop['town']) ? $prop['town'].', ' : ''?>
