PHP: print() function
The print() function used to output one or more strings. The print() is not a real function, it is a language construct. Therefore there is no need to use parentheses with its argument list.
(PHP 4 and above)
|input_string||The input string.||Required||string|
Value Type: Integer.
<?php print 'Good Morning....'.'<br>'; print 'What is your Roll No.?'.'<br>'; $roll_no = 12; print 'My Roll No. is : '.$roll_no.'<br>'; print 4567.67; ?>
Good Morning.... What is your Roll No.? My Roll No. is : 12 4567.67
PHP: Tips of the Day
In PHP, there are two versions of logical AND and OR operators.
|$a and $b||Both $a and $b are true|
|$a && $b||Both $a and $b are true|
|$a or $b||Either $a or $b is true|
|$a || $b||Either $a or $b is true|
Note that the && and || opererators have higher precedence than and and or. See table below:
|Evaluation||Result of $e||Evaluated as|
|$e = false || true||True||$e = (false || true)|
|$e = false or true||False||($e = false) or true|
Because of this it's safer to use && and || instead of and and or.
