Trying to find whether my PHP variable has any content

Question

Hi I have a PHP variable called Keyword, what I am trying to find out is if there is any content in the variable.

 if (isset($keyword)) {

Using the above code it returns values that are blank.

Answer 1

try

trim($keyword);
if (isset($keyword) && !empty($keyword)) {
    // Code here
}

Edit:

This fixed your problem because you had trailing whitespace in your variable. even though it appeared empty it still had a space or carriage return.
