Multidimensional Array problem

edpudol

Hello every body need your help for my multidimensional problem... I have the following code.

$m=array();

for ($i=0;$i <= 10;$i++){
$m[$i][]=$var;
$m[$i][]=$var2;
}
arsort($m);

foreach($m as $n => $m){
print "Student $n : Grade : $m";
}

I got weird result and an error saying

Warning: Illegal offset type

What is the problem of my script?

What I want to accomplished is that I will retrieve a data of students then store in an array the name and grade of the student... after storing it into array Sort it, after that.. display the data from highes to lowest.

thanks for the reply hope this problem got a solution from the experts....

Try [MAN]array_multisort/MAN

Also, in the foreach you're using the same variable name for the array and each element ($m and $m):

foreach($m as $n => $m)

which might work ok up to a point, but it's not really a good idea.

Giving all your variables names like $m and $n without good reason is a bad idea in itself!

Hello guys... I still don't get how to do this stuff.. I really aprreciate additional example you can provide me.

I need an example how to feed data into 2 dimensional array using loop.

example
$arrvar=array()
for ($i=0;$i < 10;$i++){
$arrvar = $studentname => $grade;
}

The code above is just an ilustration of what I want to do store the $studentname and grade to an array;

After storing those data in the array I want them now to sort descending...

arsort($arrvar);

foreach($arrvar as $student => $grade){
echo "$student : $grade";
}

That what I want to accomplished... I really appreciate if someone could point me to more specific sample or can give me a better example.

$arrvar[$studentname] = $grade;
