Body
I'm having some trouble figuring this out. I have the following CSV string <pre><code>hello world, hello world, hello </code></pre> The middle value has excess whitespaces. I'm trimming that using <pre><code>preg_replace('/( )+/', ' ', $string) </code></pre> The function is excellent but it removes the whitespaces after the commas as well. It becomes.. <code>hello world,hello world,hello</code> I want to preserve 1 whitespace after commas like so <code>hello world, hello world, hello</code> How can I do this? EDIT: Using <code>preg_replace('/(?<!,) {2,}/', ' ', $string);</code> as suggested, works but I ran into another issue.. When I use more than 1 whitespace after a comma it return 2 whitespaces after the comma. so <pre><code>hello world, hello world,hello </code></pre> returns <pre><code>hello world, hello world, hello </code></pre> As a solution I create an array from the CSV string and used <code>implode()</code> <pre><code>$string = "hello world, hello world,hello"; $val = preg_replace('/( )+/', ' ', $string); $val_arr = str_getcsv($val); //create array $result = implode(', ', $val_arr); //add comma and space between array elements return $result; // Return the value </code></pre> Now I get <code>hello world, hello world, hello</code> It also ensures a whitespace after comma if missing. It seems to work, not sure if there is better way. Feedbacks are welcomed :)

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
