What is the purpose of <<< in PHP

[babal]

Hello Everyone,

I have saw in many script usage of "<<<" operator/function i m not
sure what should i call it.
Can anyone tell me what is the purpose of this, but it sounds very
interesting & powerful.

As i saw the code it allows to print JavaScript code which is written
in PHP.

i was googling it but haven't got anything.

Thanks

The '<<<' refers to the HEREDOC method of echoing strings.

If you have a large, multi-lined block of text or code you want to
echo, instead of putting a echo " ... "; at the start of each line you
can wrap the whole lot in a code block that starts with <<<block
...
and ends with
...
block;

Have a google search under 'php heredoc', or
http://www.phpf1.com/tutorial/php-heredoc-syntax.html for more info.

Hi Babal,

The here document syntax (operator <<<) is used to output multiple
lines with $variable interpolation. Note
that the here document terminator must appear on a line with just a
semicolon no extra whitespace!

Example:

print <<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon no extra whitespace!
END;
