See more:

Problem/Question: Print the following multidimensional array, using foreach.

$grades = array(
"ali"=>array("php","50"),
"sami"=>array("php","77"),
"rami"=>array("php" )
);

What I have tried:

My code so far...

foreach ($grades as $ar_element)
{
     echo $ar_element;
     
    foreach($grades as $index => $value)
    {
         echo " Name: ".$index." , ";
    }
    
}

But, It gives me this error:

Quote:
Warning: Array to string conversion in /tmp/kF1L1NVkwY.php on line 12
Array Name: ali , Name: sami , Name: rami ,
Warning: Array to string conversion in /tmp/kF1L1NVkwY.php on line 12
Array Name: ali , Name: sami , Name: rami ,
Warning: Array to string conversion in /tmp/kF1L1NVkwY.php on line 12
Array Name: ali , Name: sami , Name: rami ,

I'm trying to have the output be something similar to:
Name: ali, Class: php ,Grade: 50

I tried researching a similar problem, but didn't find anything helpful.
I'm also a beginner in PHP.

Thank you in advance.

This is just a small problem because the variable name in your second loop is wrong

PHP

foreach ($grades as $ar_element)
{
     echo $ar_element;
     
    foreach($ar_elementas $index => $value)
    {
         echo " Name: ".$index." , ";
    }
    
}

Try this:

PHP

foreach($grades as $index => $value)
{
    echo " Name: ".$index." , value: ";
    print_r($value);
}

or this

PHP

foreach($grades as $index => $value)
{
    echo " Name: ".$index." , values: ";
    foreach($value as $elt)
        echo $elt.", ";
    echo "\n";
}
