Change Data Type Using Functions And Print Special Characters In Php

Data Type Conversion Using Functions In PHP :

Special Characters In Php

There are some other ways to change the data type of available without using Type casting. There are some functions that change the data type of a variable .

For example

intval (value) ;

It takes a value (whose data type we want to change ) as input and returns an integer data type output .

double (value);

It takes a value (whose data type we want to change ) as input and returns a double data type output .

strval (value) ;

It takes a value (whose data type we want to change ) as input and returns a string data type output .

Print Special Characters In Php :

One thing I forgot in my previous post that we can use echo or print statement for printing output on screen. If you want to print a special character on screen like double quotes (") or single quote ( ' ) or backslash ( \ ), then we can print these by using a backslash . See the example to understand

<?php

echo "He said : \ " I love Pakistan \" ";

?>

Output

He said : "I love Pakistan "

In above statement you can see that I wanted to print double quotes on the screen so that I used backslash. If you want to print the name of the variable instead of its value then use single quotes in echo statement
