Php ArrayArray :- A data structure that stores one or more similar type of values in a single value.

Use array() function to create array

Example:-

+ere !ou can find the code please click below

,GE

Three Types Of Array :-

• Numeric array - An array with a numeric index. These arrays can store numbers,

strings and any object but their index will be prepresented by numbers. By default array

index starts from ero!"#.

$%php

&' (st method to create array. '&

)num * array! (, +, , , ,/,0,1,2#3

foreach! )num as )value #

echo 56alue is )value $br &753

&' +nd method to create array. '&

)num9": * 5one53

)num9(: * 5two53

)num9+: * 5three53

)num9: * 5four53

)num9: * 5five53

)num9: * 5six53

)num9/: * 5seven53

)num90: * 5eight53

)num91: * 5nine53

foreach! )num as )value #

echo 56alue is )value $br &753

• Associative array - An array with strings as index. This stores element values in

association with ;ey values rather than in a strict linear index order.Associative array is very

similar to numeric arrays in term of functionality but they are different in terms of their

index.

<ote=- >on?t ;eep this array inside the double @uote while printing it otherwise it will not

give any return value.

%7

• Multidimensional array - An array containing one or more arrays and values are

accessed using multiple indices.ach element in the main array can also be an array,And

each element in the sub-array can be an array.

To Find The Factorial Of A Number Using PHPA factorial of a number n is the product of all the numbers between n and 1.The easiest way to calculate it is with a for !loop which one that starts at n and counts down to 1. "ach time the loop runs#the pre$iously calculated product is multiplied by

the current $alue of the loop counter and the result is the factorial of the number n.

To find the factorial number# you can use a loop to count down and multiply the number by allthe numbers between itself and 1 such as%

&'php(num ) *+(factorial ) 1+for (,)(num+ (,-)1+ (,! / (factorial ) (factorial 0 (,+ echo (,.&2br-+3

echo Factorial of (num is (factorial+'-
