It is an array that stores one or more arrays inside it.
You can access the values of inner arrays using keys or indices. After running the program, the output looks like a table.
It displays data in rows and columns.
It helps to handle the complex or structured data very easily.
Syntax:
$array_name = array(
array(value1, value2, value3),
array(value4, value5, value6)
);
Example:
$students = array(
array("Riya", 85, "A"),
array("Aman", 78, "B"),
array("Karan", 92, "A+")
);
// You will get the output after running the loop.
for($i = 0; $i < count($students); $i++) {
for($j = 0; $j < count($students[$i]); $j++) {
echo $students[$i][$j] . " ";
}
echo "\n";
}
Output:
Riya 85 A Aman 78 B Karan 92 A+
