如何在其中创建一个带null的循环

Question

I am trying to create a for that runs when $midarray[i] isnt =null.

This is the script I created:

for ($i=0; $midarray[i] !=null; $i++) { 
    $maxarray = $i;
}

I am trying to do that as long $midarray[i] isnt empty, its will run the for. I tried to use while but its didnt work.

Thank you!

Answer 1

you missed the '$' for $i

for ($i=0; $midarray[$i] !=null; $i++) { ...
                     ^
