PHP Basics

PRINT v/s ECHO :-

In the previous posts, I have used both "print" and "echo" statements.
So, let me discuss about their differences.
Echo and Print are more or less the same.
Both are used to output data to the screen.
Echo has no return value while, print has a return value of 1 so it can be used in expressions.
Echo can take multiple parameters while, print can take one argument.
Echo is comparatively faster than print.

The Echo Statement:-

The echo statement can be used with or without parentheses: "echo" or "echo()".
It can be explained further with a suitable example:-

echo.php:-

<html>

<body>

<?php

echo "<h2>Learning PHP with Fun!</h2>";

echo "This ", "string ", "was ", "made ", "with multiple parameters.";

</body>

</html>

Screenshot:-

We can display texts and variables with echo statement.
Consider an example:-

echo1.php:-

<?php

$txt1 = "Learning PHP...!!!";

$txt2 = "echo";

$x = 3;

$y = 4;

echo "<h2>$txt1</h2>";

echo "Implementing <b><i> $txt2 </i></b> statement<br/><br/>";

echo "x = $x<br/>";

echo "y = $y<br/>";

echo "The result is:- x + y =";

echo "<b>";

echo $x + $y;

echo "</b>";

The Print Statement :-

The print statement can be used with or without parentheses: "print" or "print()".
Consider an example:-

print.php:-

<?php

print "<h2>Having Fun with PHP...</h2>";

print "Using Print Statement";

Screenshot:-

We can display texts and variables with print statement.

Consider an example:-

print1.php:-
<?php
$txt1 = "Learning PHP...!!!";
$txt2 = "print";
$x = 3;
$y = 4;

print "<h2>$txt1</h2>";
print "Implementing <b><i> $txt2 </i></b> statement<br/><br/>";
print "x = $x<br/>";
print "y = $y<br/>";
print "The result is:- x + y =";
print "<b>";
print $x + $y;
print "</b>";
?>
