In PHP, should we use "print" or "echo" and what is the difference?

We will use "echo" because it is more faster than "print".And it takes multiple parameter."echo" does not return any value on the other hand "print" return alway 1.

echo and print are both same, both used to output data on screen.

The difference is minor echo has no return value where as print hav return value 1 so it can be used in expression.

Also echo can take multiple arguments (very rare case in use)   where print takes single parameter.

Also echo is slightly faster than print.

Both Echo and print are use to output data on the screen but echo has no return value whereas 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.

1.   print only takes one parameter, while echo can have multiple parameters.

     Example:

         echo 'foo', 'bar';   // Concatenates the 2 strings

         print('foo', 'bar'); // Fatal error

2.   print returns a value (1), so can be used as an expression.

     Example:

         $res = print('test');

         var_dump($res); //bool(true)

Note: If you're looking to evaluate the outcome of an output statement use print. If not, use echo.     

3.   echo is faster than print.

echo and print are more or less the same. They are both used to output data to the screen.

The differences are small:

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 (although such usage is rare) while print can take one argument. echo is marginally faster than print.

Echo = Outputs one or more strings separated by commas and No return value e.g. echo "String 1", "String 2"

Print = Outputs only a single string. Returns 1, so it can be used in an expression e.g. print "Hello" or, if ($expr && print "foo")

Print can only be used for single argument but Echo can take more than one parameter

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. 

yes we use.They both are use to print data on screen.

The main difference is echo has no return value and print has return value 1.

Echo has no Return value while print has

Both used to output data to user screen 

The differences  between :

echo has no return value  while print has 

echo can take multiple parameters but print take one
