Echo and Print statements

Echo and print Statements.
  • In PHP there are two basic ways to get the output: echo and print.
  • echo and print are almost both are same. They are used to output data to the screen.
Echo Statement
  • PHP echo statement can be used to get the output of the string, multi-line strings, escaping characters, variable, array, etc.
  • echo is faster than the print statement.
  • PHP echo is a language construct, not a function.
  • echo can be used both types: echo(), and echo.
  • echo does not return any value.
  • We can pass multiple strings separated by a comma , in echo.
  • examples of echo statement
    • <!DOCTYPE html>
<html>
<body>

<?php
echo "<h3>PHP is Fun!</h3>";

echo "Hello PHP Coders!<br>";

echo "This ", "string ", "was ", "made ", "with multiple parameters.<br/>";

echo "I'm about to learn PHP from PHP Coders point!<br/>";

echo "Hello PHP coders
this is multi line
text printed by
PHP echo statement.<br/>";

echo "Hello PHP Coders escaping characters : \"sequence\" characters.";
?>
</body>

echo "Study PHP at " . $var2 . "<br/>";
echo $var1." at " . $var2 . "<br/>";
echo $a + $b;
?>

    Print Statement
    • The print statement can be used with or without parentheses: print or print().
    • PHP print statement can be used to print the string, multi-line strings, escaping characters, variable, array, etc.
    • print is a statement, used as an alternative to echo at many times to display the output.
    • print always returns an integer value, which is 1.
    • Using print, we cannot pass multiple arguments.
    • print is slower than the echo statement.
