Print always returns a value of true, but echo doesn't.
echo also has a short cut syntax meaning you can immediately follow the php tags by an equals sign and it will echo the result like in the example shown below:
<?=$hello?>
The print function is slightly more dynamic than the echo function by returning a value, and the echo function is slightly (very slightly) faster. The printf function inserts dynamic variables/whatever into wherever you want with special delimiters, such as %s, or %d. For example, printf('There is a difference between %s and %s', 'good', 'evil') would return 'There is a difference between good and evil'.
displaying a variable in php using echo statement? <?php $name="ram"; //declaring and defining the variable echo "$name"; //printing the variable using echo command ?>
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!
Assuming you just want those integers printed you can do so like this: <?php echo 1; echo 121; echo 12421; echo 1248421; ?> However, if you're looking for how to print these in some sort of power of 2 in terms of a homework assignment, you can pretty easily find some hints by simple searching the significance of those numbers.
Code Below: <?php $j = 100; // Set limit upper limit echo "Even Numbers are: <br/>"; for($i=1;$i<=$j;$i++) { if($i%2) { continue; } else { echo $i."<br/>"; } } ?>
echo or print < both of which write text: <?php echo "TEXT"; print "TEXT"; ?>
> You can use PHP variable name inside the double quote ("") Eg:- $name = 'Udit'; echo "Hello $name"; It will print: Hello Udit

I think you mean language construct... Anyway, a function usually takes one or more arguments as comma separated values or variables. echo and print don't <?php $email = 'user@example.com'; $domain = strstr($email, '@'); echo $domain; // prints @example.com ?> Here the strstr function takes a variable string and a constant string as an argument. echo simply displays the contents of the resulting variable. There are a couple functions that don't require arguments, like die() & exit()

Via AJAX. Another simpler way would be to use form elements and submit them via html and let PHP process the data. Processed data can be output in html form via echo or print statements in php.
Build your form in HTML and specify your PHP file in the action of the document. HTML does the form stuff, PHP the processing (although you can - of course - use HTML inside PHP via print() or echo(), too)
Code Below: <?php $j = 100; // Set limit upper limit echo "Even Numbers are: <br/>"; for($i=1;$i<=$j;$i++) { if($i%2) { continue; } else { echo $i."<br/>"; } } ?>
in PHP: for($n = 5; $n >= 1; $n--){ for($m = 5; $m >= $n; $m--){ echo $m; } echo " "; }
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>"; ?>
