PHP Tutorial Part 4 :PHP Print

 PHP Print

Like PHP echo, PHP print is a language construct, so you don't need to use parenthesis with the argument list. Print statement can be used with or without parentheses: print and print(). Unlike echo, it always returns 1.

The syntax of PHP print is given below:

int print(string $arg)  

PHP print statement can be used to print the string, multi-line strings, escaping characters, variable, array, etc. Some important points that you must know about the echo statement are:

• print is a statement, used as an alternative to echo at many times to display the output.
• print can be used with or without parentheses.
• print always returns an integer value, which is 1.
• Using print, we cannot pass multiple arguments.
• print is slower than the echo statement.
