In every programming language available today, there is usually more than one way to display output to the screen. PHP has two methods: 
- `echo` statements.
- `print` statements.

# 
#  `echo` statements
This is the most commonly used of the two functions used to display output in PHP. **`echo`** can be used with or without parentheses and can take several strings and variables concatenated together.
##  
## Code

<?php
$toDisplay = 200;
$$toDisplayMyName = ',You will see me on screen';
$insideHtml = ",An Html paragragh,";
//can display content of a variable be it a string or not
echo $toDisplay;
echo $$toDisplayMyName;
//used to dispay a string which must be qouted "" or '';
echo ",Now is double qoute";
echo ',Now is double qoute';
// can display concatenated strings and variables;
echo ",You can display string & variables".$toDisplay;
//can also be used to echo html codes/components
/* echo '<P>'$insideHtml'</p>'
This won't exucute properly here becuase this
playground only understand php code.
*/;
//using it with parentheses
echo (",used with parentheses");
// Can take multiple comma separated parameters
echo $insideHtml,$$toDisplayMyName,$toDisplay;
?>

The code above includes scenarios of how we can use the `echo` statement. 

# 
#  `print` statements
The **`print`** statement in PHP is what you might call a *pseudo* function. This is because it returns a value `1` like a function, but it is not callable like functions are. 

Although the `print` statement can be used in almost the same way as the `echo` statement in the code above, it cannot print multiple parameters. The `print` statement's main importance is that it can be used inside expressions and even in conditions, unlike the construct `echo`, which must be used at the start of a new line.
##  
## Code 

<?php
$m = 4;
$n = 5;
//you can say  do
echo print $n + $m; 
/*where 1 in the output of above code is
 the return value of print.*/
//but not
print echo $n + $m;   
/*Above will throw an error
*comment it out to see the output of others*/

?>

You can also use the `print` statement to do print out to the screen inside your conditions, as shown below.

<?php
/*This code will increment the counter with 
the return value of the print statement while
printing the curent value of the counter.*/
/*the echo will 
display the final value of the counter*/
for ( $i = 0; $i < 10; $i += print "$i," );{
    echo $i;
}
?>

Try exchanging `echo` for `print` and vice versa in the code above and see what happens.


Differences between echo and print statements

align-center

What is the difference between PHP print and echo statements?

Echo is versatile and can't return values; print returns 1 and is usable in expressions.

	Echo	Print
1	Can output multiple parameters	Only outputs concatenated strings or parameters
2	Has no return value	Has a return value of 1
3	Returns nothing, and is slightly faster	Has a return value, and slows down slightly
4	Can't be used within expressions	Can be used within expressions and conditions
