Running an If statement within a For loop to change last string-CodePudding

I am trying to output an array that looks like this

[data, data],
[data, data],
[data, data]

The last string should be echoed without a comma.

My For loop looks like this:

    
    for ($i = 0; $i < $count; $i  )
    {
        echo "[" . $result[$i]->dato . ", " . $result[$i]->vaegt . "]";
        
        if ($i < $count) {
            echo ",<br>";
        }
    }

It echoes out the correct strings but the comma is still there in the last string. It seems like the If statement is still reading the last string?

CodePudding user response：

You need to check condition for n-1.

for ($i = 0; $i < $count; $i  )
{
    echo "[" . $result[$i]->dato . ", " . $result[$i]->vaegt . "]";
    
    if ($i < $count-1) {
        echo ",<br>";
    }
}
