Print 2 items of array per line and separate by comma

Question

can u please help me on this. I have an array with 6 items, I want to print 2 items per line separated by commas, I have this code:

$rates[] = array("2020-01-01"=>3000);
$rates[] = array("2020-01-02"=>3010);
$rates[] = array("2020-01-03"=>3020);
$rates[] = array("2020-01-04"=>3021);
$rates[] = array("2020-01-05"=>3030);
$rates[] = array("2020-01-06"=>3035);

$rates_count = count($rates);
$total = $rates_count;
$col = 2;

for ($i = 0; $i < $total; $i++) {

    $date = key($rates[$i]);
    $value = end($rates[$i]);

    if ($i % $col != 0) {
            echo "{$date},";
            echo "{$value},";        
    } else {
        echo "{$date},";
        echo "{$value}";
        echo "</br>";
    }
}

This code print this:

2020-01-01,3000
2020-01-02,3010,2020-01-03,3020
2020-01-04,3021,2020-01-05,3030
2020-01-06,3035,

I want this:

2020-01-01,3000,2020-01-02,3010
2020-01-03,3020,2020-01-04,3021
2020-01-05,3030,2020-01-06,3035

Where is the error? Thanks for any help.

The solution is merely to invert the logic from `!=` to `==`. There isn't much to teach here. — mickmackusa, Jul 11 '22 at 03:53

I tested this and your output should be correct now

if ($i % $col == 0) {
        echo "{$date},";
        echo "{$value},";        
} else {
    echo "{$date},";
    echo "{$value}";
    echo "</br>";
}

Output:

2020-01-01,3000,2020-01-02,3010
2020-01-03,3020,2020-01-04,3021
2020-01-05,3030,2020-01-06,3035

I changed the comparison to be " == 0"

The first value in the iteration will be cero because 0 % 2 = 0

0 % 2 = 0
1 % 2 = 1
2 % 2 = 0
3 % 2 = 1
4 % 2 = 0
5 % 2 = 1
... and so on

The condition was returing false in the first iteration, it was fixed by changing the comparison of the remainder to be equal to cero.

This answer is missing its educational explanation. – mickmackusa Jul 11 '22 at 03:50 — mickmackusa, Jul 11 '22 at 03:50
