使用date（）和in_array（）或array_key_exists（）

Question

Here is an array I have to work with:

array ( [0] => monday [1] => thursday [2] => saturday [3] => sunday )

I need to run an if/else statement to check if today's day is in that array. This does not work

// Pretend today is thursdsy
$day = date('l');
$list = array ( [0] => monday [1] => thursday [2] => saturday [3] => sunday );

if ( array_key_exists($day, $list) ) {
    echo "its there";
} else {
    echo "not there";
}

Neither does the in_array() version. Not sure if there is a problem using the date() with either of these functions?

If I print_r the $day i get the correct value 'thusday'

Answer 1

Your list has the data in the values instead of the keys.. that is why array_key_exists is failing. Instead use in_array (also since your array week days represented in all lower case... you should do the same with with the supplied $day to get a match)

if (in_array(strtolower($day), $list){
   // whoop there it is..
} else {
   // not here.
}
