What does <? php echo (“”); … echo(“”); ?> mean?

Question

The question is the tag

I\'ve seen one script I am working on, uses it:

echo (\"

\");


....
.         


        

Answer 1

The PHP function echo() prints out its input to the web server response.

echo("Hello World!");

prints out Hello World! to the web server response.

echo("");

prints out the tag to the web server response.

echo do not require valid HTML tags. You can use PHP to print XML, images, excel, HTML and so on.

is not a HTML tag. Is is a valid XML tag, but since I don't know what page you are working in, i cannot tell you what it is. Maybe it is the root tag of a XML page, or a miswritten

 tag.
