echo a string that contain <? and <?php

[haoren]

Can anybody help me with this problem:

How can I echo a string that contain <? and <?php?

For example,

$str="test <? and <?php echo";
echo $str;
What I get is: test instead of: test <? and <?php echo
Thanks.

Just use single quotes:
<?php
$string = 'test <? and <?php echo';
echo $string;
?>

You should _never_ be echoing a < or > char to the browser, this should
_always_ be &lt; or &gt;.
echo htmlentities($s tr);
would work in your instance for example.

That's interesting... How do you output HTML from PHP then? :-p

What he's trying to say is that if you want a < or a > to show up in
your browser, you should use &lt; and &gt;, since < and > are the chars
used to delimit HTML tags, so the browser will think that the < or > you
just echo'ed out is part of the HTML.
So, again... If you want < and > to print in e.g. a text, use 'echo
"&lt; and &gt;";'

lol oops =)

Yup, that pretty much sums it up.. I was referring to if you wanted to
display < or > chars, they should _always_ be entities rather than their
actual chars.

FWIW.. I rarely output HTML from PHP... gotta love Smarty ;)

I should have put the question in the context. In fact, the string is
received from user's input to the form of a browser. Thus, echo
htmlspecialchar s($str); can solve the problem.

Thanks Michael and all you guys.
