There are several different ways to output text on the screen in PHP two of the most common are echo and print. echo "Hello World!"; print ("Hello World!"); Would both print ... Hello World!
displaying a variable in php using echo statement? <?php $name="ram"; //declaring and defining the variable echo "$name"; //printing the variable using echo command ?>
ord() is the function you need. echo ord(' '); Would output the number 32.
Example: <?php $value = 10; $i = 0 if(is_int($value)) { while($i < $value) { echo $i; echo '<br/>'; $i++; } } ?>
You can do this: <?php if ( $word === strrev( $word ) ) { echo "The word is a palindrome"; } else { echo "The word is not a palindrome"; }
echo or print < both of which write text: <?php echo "TEXT"; print "TEXT"; ?>
type this in a file save it as something.php and then run it <?php echo '*'; ?>

use the round function. For eg: <?php $value1 = 15.55; echo round($value1, 0); // Will output 16 $value2 = 20.666666666; echo round($value2, 2); // Will output 20.67 ?>
The only true form of previewing PHP source output is to run the PHP script in question.
This program only suits PHP. If you want a proper one try C program for it available on web <body> <?php if(isset($_POST['submit'])) { $text = $_POST['text']; $string = mysql_real_escape_string($text); $invert = strrev($string); if($string == $invert) { echo "<br>Given number is a palindrome!!"; } else { echo "<br>Given number is not a palindrome!!"; } } ?> <form method="post"> <input type="text" name="text" id="text" /> <input type="submit" name="submit" value="Submit" id="submit" onclick="<?php $_SERVER['PHP_SELF']; ?>" /> </form> </body>
<?php $a = $_POST['name2']; if($a=='Hello'){ echo "VALUE IS HELLO";} else{ echo "VALUE WRONG";} ?> <form name="" method="POST"> <input type="text" name="name2" value="Hello"> </form> <?php ?>
That depends, it may be HTML script "translated" into normal text, as BBCode where you can make bold text, and it can be HTML which is translated into for example PHP with echo tags.
The function die() stops the script from running. See the example below: <?php die("this text will be outputted on the page"); echo "this text will not be shown due to the script ending when the die() function was called"; ?>
Yes. For every web based programming language the final output is browser readable html text

Its done exactly the same as when you put it in an HTML file. There are 2 ways you can do it: <html> <?php // php stuff ?> </html> Or you can do it like this: <?php echo "<html>"; // php stuff echo "</html>"; ?>
