Echo In PHP

In order to output one or more strings, we can use echo statement. Anything that can be displayed to the browser using echo statement, such as string, numbers, variables values, the results of expressions, etc. It is required to use parenthesis if you want to use more than one parameter. Unlike some other language constructs echo does not behave like a function, so it cannot always be used in the context of a function. The end of echo statement is identified by the semi-colon (‘;’). 

Below example demonstrates the basic usage of echo in PHP

<?php
$content = "PHP course";
$num=50;
$num1=60;
$char='c';
echo $content."<br>";
echo $num."+".$num1."=";
echo $num + $num1."<br>";
echo "this is my statement";
?>&nbsp;

Below example demonstrates the example of using HTML code using PHP

<?php
echo "<h1>This is html.</h1>";
echo "<h2 style='color: blue;'>This is heading with style.</h4>";
?>
