How to append text to specific php array value

Question

I need to find certain keys in an array created by a MySQL query, once I have that key, I need to append some text to the value that the key is linked to

Ive figured out how to identify the key value with array_key_exists... I just need the code to append text to the associated value of the key

if(array_key_exists("note", $row_dailyNotes))
{
    // stuck here
    $row_dailyNotes(value) = $row_dailyNotes(value)."text to append"
}

You can't assign a value to a function. Fix your code first. — hakre

Probably what you're looking for is:

$array[$key] = $array[$key] . "text to append";

This uses the array syntax to look up a value or set a value in a PHP "array".

Example:

$array["something"] = $array["something"] . "blah blah";

There's also a short form using .= (the string concatenating operator):

$array[$key] .= "text to append;

isnt that appending to the key not the value?

@user1222646 - No, $key .= "sometext" would append to the key.

@user1222646: That is appending to the value, not the key. See php.net/Array
