undesirable linebreak after heredoc

[supercain]

Hi,

i have the following code

$bye=<<<EOF
<span>goodbye</span>
EOF; 

     <td class="header_right">
       <span>hello</span>
        $bye 
     </td>

which outputs:

     <td class="header_right">
       <span>hello</span>
       <span>goodbye</span>

     </td>

as you may see, there is a double line break between the last </span> and the </td> which should not be there. How can i take it out? Below there is a temporary solution:

     <td class="header_right">
       <span>hello</span> 
      $bye </td> 

but this outputs something like this:

     <td class="header_right">
      <span>hello</span>
     <span>goodbye</span>
</td>

which doesnt look good either, since the last </td> wont align with the rest of the code. If i give some extra tabs between $bye and </td> like this

     <td class="header_right">
       <span>hello</span> $bye     </td> 

then i get what i want but it just doesnt feel right. there must be a cleaner way to do it. Isnt?

Thank you.

What's the difference? It doesn't matter what spaces are there.

Why is the extra spacing bothering you?

[supercain]

Because it doesnt look good in the source code. Im quite picky when it comes to presentation and that space just doesnt look right. I know many web developers dont care about how their code look but i do. I want it to comply with HTML tidy standards.

Read up on the trim function
the reference manual is an invaluable source of information, which reminds me of a neat extension I picked up for chrome, PHP Ninja Very useful tool

[supercain]

Thanks. I know the trim function but i think i fail to figure out how can use it so i can remove only and exactly the last break of the text. Actually i still dont understand why do i get that break since there is nothing between the last line of code and the EOF;

Spaces/Tabs/Line breaks and tidy html in general is a waste of bandwidth.
I personally prefer to strip everything unnecessary. Just make sure the code you write is clean.

Sorry if that doesn't help your current problem, but I gave up making the output looking pretty a long long time ago. I found that under different circumstances you needed some html to be more indented than in other places, what then?

[supercain]

I respect your preference and i know what you mean, but having a clean and readable code makes it easy to edit. Thats why i want it to comply with tidy standards.

If it's important enough to you that you don't mind a few milliseconds of extra processing: http://www.charles-reace.com/blog/20...put-with-tidy/

[eval(BadCode)]

I guess you could do this:

<?php 
echo trim(<<<EOF
<span>goodbye</span>
EOF
);

That's the closest I could come up with to removing the tailing \n. Although it does not match your example, I'm just showing the syntax.

Ran it with PHP 5.3.5-1ubuntu7.4 with Suhosin-Patch (cli) (built: Dec 13 2011 18:25:14)

Heredoc does some funky stuff with white spaces sometimes... Might be better to rethink what you have going on and use the more standard variable declaration using quotes and all...

[MrCoder]

Have you tried...

$bye=<<<EOF 
<span>goodbye</span>EOF; 

[NogDog]

Have you tried...

$bye=<<<EOF 
<span>goodbye</span>EOF; 

The "EOF;" (or whatever string you choose) must be the only thing on its line (including no leading white-space).

Was worth a shot

[eval(BadCode)]

you did see my example correct?

The "EOF" MUST be on it's own line, the semicolon can be 1000 lines down and not exclusively separated by \r, \n, and spaces. I put a ) there to close trim.

It does run...

I would only recommend on top of that to use rtrim instead, just incase leading whitespaces or tabs were required for formatting.

Modified from eval(BadCode) previous submission:

<?php

$bye = rtrim(<<<EOF
<span>goodbye</span>
EOF
);

echo $bye;

?>

Tested.
