Explain Indexed array and Associate array in PHP?

Answer»

Indexed Arrays: Arrays with numeric index for the available values in array variable which contains key value pair as user / developer can take the values using keys.

Example:

<?php

$teacher_name=array(“Iniyan” , “Kavin” , “Nilani”);

echo “The students name are “ .$teacher_name[0]. “ , “

. $$teacher_name[l]. “ and” . $teacher_name[2].

?>

Associative Arrays:

1. Associative arrays are a key-value pair data structure. 

2. Instead of having storing data in a, linear array, with associative arrays you can store your data.

Example:

<?php

$Marks=array(“Studentl” =>“35” , “Student2” ==>“17” , “Student3” =>“43”);

echo “Studentl mark is” . $Marks[‘Studentl’]. “ is eligible for qualification”;

echo “Student2 mark is” . $Marks[‘Student2’]. “ is not eligible for qualification”;
