echo.print.echo and print are both used to output data to the screen.
differences :
echo print
no return value return value of 1
take multiple parameters take one argument.
faster than print.
for example:
<?php
echo "<h2>Hello world!</h2>";
print "Learn PHP from Bajarangisoft!";
?>
How can we view output with a return in a loop.
first create function in that declare one variable as $output and assign empty string after that create for loop using $i variable and for each iteration $i get incremented and at the end of loop data get return when we call function.
for example:
function myfunction()
{
$output = '';
for ( $i = 1 ; $i <= 10 ; $i++ )//from 1 incremented upto 10
{
$output .= $i;
}
return $output;
}
call function to display output:
echo myfunction();
<!DOCTYPE html>
<html>
<head>
<title>Display my output in PHP with a return in a loop</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">

<body>
<div class="container">
<br>

<div class="text-center">
<h1>Display my output in PHP with a return in a loop</h1>
</div>
<br>
<br>
<div class="well">
<?php
echo "<h2>Hello world!</h2>";
print "Learn PHP from Bajarangisoft!";
function myfunction()
{
$output = '';
for ( $i = 1 ; $i <= 10 ; $i++ )
{
$output .= $i;
}
return $output;
}
echo "<h1>".myfunction()."</h1>";
?>
</div>
