Description:
------------
---
From manual page: http://www.php.net/function.print
---

Both echo and print output a string. 

The similiarity and differences should be described.
 (syntax, performance, buffering, alias ..???)

I use 'print' when I'm programming in Perl, I use echo when programming in PHP.
Now I learned there is also 'print' in PHP? So can I just forget 'echo' and always use print? :-)

The only relevant difference is that `print` accepts only one
argument, while `echo` accepts a comma separated list of
arguments.

As of PHP 7.0.0 both statements compile to the same opcode, namely
ZEND_ECHO, see <https://3v4l.org/lncp9/vld#output>. Formerly, they
had different opcodes (ZEND_ECHO and ZEND_PRINT), but ZEND_PRINT
forwarded to ZEND_ECHO, which might have made `print` slightly
slower.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
