array bugs?

[7h]

Sorry if I sounds like a noob (because I am one, here). I ran across
this earlier, and it kept bugging me. I guess someone here know a good
answer.

To summerize, I was using array within a class. After some
manipulation, the value of the array's element that I needed wasn't
"echoed" right.

For instance,

class FootballClub
{
public $name;
public $stadium = "junkyard";
public $roster = array("gk"=>"cl own", "st"=>"fool ");
public $coach;
}

$myclub = new FootballClub();
$myclub->name = "Liverpool" ;

if ($myclub->name == "Liverpool" )
{
$myclub->stadium = "Anfield";
$myclub->coach = "Rafa Benitez";
$myclub->roster["gk"] = "Pepe Reina";
$myclub->roster["st"] = "Robbie Fowler";
}
$myplayer = $myclub->roster[gk];
echo "your team plays at: $myclub->stadium<br>" ;
echo "your goal keeper is: $myclub->roster[gk]<br>");

---------
Problem:

As is, the 2nd line output is: "your goal keeper is: Array[gk]" thought
$myplayer gets the right value.

Any plausible explaination, please?

Thanks.

As is, the 2nd line output is: "your goal keeper is: Array[gk]"

echo "your goal keeper is: {$myclub->roster['gk']}<br>");

Note the curly braces and quotes.

Yup, see Complex (curly) syntax:

Although not strictly necessary in php, always put your variables
outside of quotes. This came to me easily as I was developing in c and
C++ before I moved on to PHP.

Hmm. I looke at someone else's answer of putting braces in. I thought to
myself, "Great, I just learned something by reading this newgroup. Store it
away". When I saw your response I thought to myself "Why hadn't I come
across this problem before, myself?". Well, your answer showed me why. I
would have written it as:

echo "your goal keeper is:" . $myclub->roster['gk'] . "<br>";

and never have had that difficulty. My background in C and java developed
that same habit in me.

It could be done like that, for sure (allthough I'd use single quotes for
text without variables & newlines). When outputting HTML tags however, it
can become a complete quote-fest, that I'd rather avoid to improve
legibility. Heredoc & curly often come to the rescue, allthough certainly
for numberformattin g, but also for strings, (s/v)printf() is certainly an
outcome.

Consider:
array product{
[id] =>.....
[name] =>...
[decription] =...
[image_src] =...
.....
}

Concating way:

echo '
<h2>'.$produc t['id'].':'.$product['name'].'</h2>
<p>
<a href="./products/?id='.$product['id'].'"><img
src="'.$product['image_src'].'" /></a>
'.$product['decscription'].'
let\'s say way have to use singel quote\'s here... escaping?
Read more about <a
href="./products/?id='.$product['id'].'">'.$produc t['name'].'</a>
</p>';

Double quotes, curly:

echo "
<h2>{$product['id']}:{$product['name']}</h2>
<p>
<a href=\"./products/?id={$product['id']}\"><img
src=\"{$product['image_src']}\" /></a>
{$product['decscription']}
let's say way have to use singel quote's here... escaping?
Read more about <a
href=\"./products/?id={$product['id']}\">{$product['name']}</a>
</p>';

Heredoc, curly

echo <<<HTML
<h2>{$product['id']}:{$product['name']}</h2>
<p>
<a href="./products/?id={$product['id']}"><img
src="{$product['image_src']}" /></a>
{$product['decscription']}
let's say way have to use singel quote's here... escaping?
Read more about <a
href="./products/?id={$product['id']}">{$product['name']}</a>
</p>
HTML;

Printf possibility:

vprintf(<<<HTML
<h2>%1$03d:%2$s </h2>
<p>
<a href="./products/?id=%1$d"><img src="%4$s" /></a>
%3$s
let's say way have to use single quote's here... escaping?
Read more about <a href="./products/?id=%1$d">%2$s</a>
</p>
HTML;
, $products);

The latter one might come in handywhen outputting a list from an array
(allthough the code isn't really charming):

$list = array('page 1','page 2','page 3'....
vprintf(str_rep eat("\n<li>%s</li>", count($list)),$ list);

It's all about legibility, what you're actually doing, wether it has to be
easily maintained and wether it's a repeating output.

Sometimes I use single and sometimes double if there is no necessity to
choose between them. See below.

let\'s say way have to use singel quote\'s here... escaping?
Read more about <a
href="./products/?id='.$product['id'].'">'.$produc t['name'].'</a>
</p>';

Here I would do the preceding without needing escapes:

echo ' <h2>' . $product['id'] . ':' .$product['name'] .
'</h2><p><a href="./products/?id=' . $product['id'] . '" ><img src="' .
$product['image_src'] . '" /></a>' . $product['decscription'] .
"let's say way have to use single quote's here... escaping?Read more
about <a " .
'href="/products/?id=' . $product['id'] . '">' . $product['name'] .
'</a></p>';

Putting in spaces between the concatonation dots greatly improves
legibility. Also, not needing the extra escape character (when it can be
avoided) also does that.

vprintf(str_rep eat("\n<li>%s</li>", count($list)),$ list);

It's all about legibility, what you're actually doing, wether it has to be
easily maintained and wether it's a repeating output.

I agree with this last statement 100%. That is why I always put in a spaces
where possible and end the first line with the concatonation dot to and
start the second line in the right indent position.

Thanks all.

Guess I gotta take out some of the sloppy coding habits ;-)
