PHP echo function

PHP echo function: Echo function is used to print the strings in php.

PHP echo function Syntax

echo strings

strings : Input Strings.
Return : Will print string.

Note 1 : Parenthesis are not required as “echo” is not function actually. It is construct. So you need not to use parenthesis with the echo.

Note 2 : Echo is faster than the print so we prefer to use echo instead of print.

$string = "Hi It's me Kelly!";
echo $string;

As you see in the above example we have not used the parenthesis like this :echo($string) which is incorrect.

The below example shows the concatenation of the two strings.

$string1 = "Hi I am John !";

$string2 = "A Young Developer.";

echo $string1.' '.$string2;

Output of the above example will be :

PHP echo() Function Example
