Question

Anyone know what I’m doing wrong?

From the following array I want to count the the number of times “Friday” occurs.

Array ( 
[404979509517702] => Array ( 
    [0] => 235 
    [1] => 04:10,Friday 
) 
[404045862944400] => Array ( 
    [0] => 192 
    [1] => 23:52,Wednesday 
) 
[20403274909688162] => Array ( 
    [0] => 186 
    [1] => 22:21,Tuesday 
) 
[202735273075459] => Array ( 
    [0] => 336 
    [1] => 04:29,Tuesday 
) 
[652948031457462] => Array ( 
    [0] => 410 
    [1] => 06:22,Monday 
) 
[2606749954978] => Array ( 
    [0] => 312 
    [1] => 05:01,Saturday 
) 
[755318061725] => Array ( 
    [0] => 384 
    [1] => 04:51,Friday 
)
)

This is what I’m doing:

$friday = array();
foreach ($the_array as $friday){
    $the_array = explode(',', $friday[1]);

    $the_array[$the_array [1]] += ($friday[1]);
}

print_r($friday);

This way, I get the wrong number of “Friday” occurrences.
Any idea what I’m doing wrong or if there is a more elegant solution to that?

Answer 1

I would try something like the following if all you want to do is count occurrences:

$friday_count = 0;
foreach($the_array as $record) {
    // Search for "Friday"
    if(stristr($record[1],'Friday') !== false) {
        $friday_count++;    // increment count
    }
}
