PHP Array Help

Question

The associative Array in PHP language can be define/declare through Array() function and can take any number of key-value pairs. The indices/keys of an associative array can be numeric or string.

Write a small program (Code) in PHP language which declares an array of five students named “Student”. The key/index of this array would be students’ roll numbers while the values would be their names. Also print students’ names on the screen.
Sample output:
Student 1: Ahmed Ali
Student 2: Ikram
Student 3: Sumair
Student 4: Imran
Student 5: Shabeer

Answer 1

So the first step is to set up an array. As the first sentence of your problem mentions, you can define an array in PHP by simply using the array() function and providing key-value pairs. In this case, since your index (key) is the roll number and the value is the students' names, you can do the following:

 

$student = array(

1 => 'Ahmed Ali',

2 => 'Ikram'

);

 

I've only put two students here, as you should be able to put the rest on your own.

 

To print the array, you can use a foreach loop. This will loop through each element and you can print one at a time.

 

foreach ($student as $key=>$value) {

echo 'Student ' .  $key . ': ' . $value . "\n";

}

 

You can also use the built-in print_r() function and pass in the array you need.
