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"
}
$row_dailyNotes['note'] .= 'text to append';
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;
我想你应该像这样使用连接运算符:
$row_dailyNotes[$key] .= "text to append";
