Re: [PHP] array question
Tanks for all of your responses!
I guess a function is the way to go. I just have to see if the situation
comes up enough times to justify the function approach.
@Dan: I really enjoyed your disclaimer :D

[PHP] array question
Hello all!
I have a question regarding arrays and the way I can use a value.
Let's say I have this string:
$s = 'banana,apple,mellon,grape,nut,orange'
I want to explode it, and get the third value. For this I would normally do:
$a = explode(',', $s);
echo $s[2];
That's all fine, but is there a way to get the value directly, without
having to write another line in my script. I mean something like this:
echo explode(',', $s)[2];
or
echo {explode(',', $s)}[2];
I couldn't find out this answer anywhere, that's why I posted here.
Cheers and thanks!
Re: [PHP] eval and HEREDOC
Hi Peter!
In the first version of the template engine I had markers but now I
need more complex conditions or operations inside the template files,
like array of arrays and so on. I really like the freedom to be able
to just open a PHP tag and use a foreach() or whatever PHP
function as I please.
Thanks again to all of you for your support! :)

Re: [PHP] eval and HEREDOC
@Vincent: no, the short tags are not off.
@Jim: This seamns to work fine:
$template = file_get_contents(pathTemplates.$this->dir.$this->tpl);
ob_start();
$template = eval('?>'.$template);
$template = ob_get_clean();
Thanks!

Re: [PHP] eval and HEREDOC
Hello Vincent and thank you for your reply :).
That's true, I forgot to explain how I got to using HEREDOC, so ..
Using eval(file_get_contents($file)) just outputs the result on the
spot and I need
to get the whole output (without echoing it) and do some more things with it.
require_once() doesn't fit here (from what I can tell), because it
would still just
include the file in echo the output.
I think there must be a solution, but I'm missing something here ..
Thanks again!

[PHP] eval and HEREDOC
Hello, I am having trouble with a part of my templating script. I'll try to explain: The template itself is HTML with PHP code inside it, like: And I have the following code as part of the templating engine: $template = file_get_contents($file); $template = "return << If in the HTML file (template) I use I get as an output. I have tried closing the php tag like this: $template = "return <<".$template."\nTEMPLATE;\n"; but the extra ?> only gets outputed as HTML.
