PHP tags within PHP tags

[Xu Wei Jie]

Hi all,

 

I need help on this. If I have a php tag <?php ?> within another php tag. How do I process the inner tag as just plain text without the CLI interpreting it? Do I need to write some config file for the CLI or do I use a flexible parser? I am clueless. Any ideas or suggestions would help.

 

Regards,

Tags enclosed in quotes are not interpreted, and I don't think you need tags outside quotes.

[Xu Wei Jie]

Would it be a single quote or double quote? What if the inner tag also contain quotes? Won't the coding get very messy?

[Mchl]

Could you show example of what you're trying to achieve?

[Xu Wei Jie]

It goes like this

 

<?php echo '<?php echo $result[\'Title\'];?>'  ?>

 

I am just wondering if there is a more elegant way of doing it.

 

[Mchl]

This should work all right.

 

In PHP 5.3.0 the NOWDOC syntax will be introduced, which will be a bit more elegant, but until then there isn't really much more you can do about it.

 

You might also want to check highlight_string function.

Where do I download PHP 5.3.0 from? My current version is 5.2.8. The highlight function does not seem to be of usage as it inserts HTML codes.

[Mchl]

5.3.0 has not been released yet. You can download development version from php.net.

[Xu Wei Jie]

Do you have the link to the development version? I can't seem to find it on php.net. Thanks very much for your help

I am not sure how to install the development version. Thus, I tried the windows build at this link http://windows.php.net/snapshots/. However, I still cannot get it to work. It reports a PHP parse error.

 

The test code I tried to parse according to NOWDOC syntax

 

<?php

echo <<<'EOT' echo "Hello world!" EOT;

?>

 

Any idea?

[MasterACE14]

change it to this..

<?php
echo <<<EOT
echo "Hello world!" 
EOT;
?>

[Xu Wei Jie]

There is still a parsing error on line 2 =(

[MasterACE14]

try...

<?php
echo 
<<<_EOT
echo "Hello world!" 
_EOT;
?>

 

and what's the parse error?

[Xu Wei Jie]

I think I got it solved. I was using a notepad to edit the php file. Thus, it may introduce some unwanted new lines or returns in the nowdoc statement. So I guess I must be careful with it. Another question is that I cannot use nowdoc to create single line statements like echo <<<'EOT' test EOT;. It will still parse wrongly. Any way to work around it?

[Mchl]

No. That's how Nowdoc works. Read about it manual.

For single lines you can just use single quotes.

 

echo 'echo "Hello world!";';
