Hello all.
Can someone tell me which of the following is preferred and why?
echo "<a style='text-align:left;size:14;font-weight:bold' href='/
mypage.php/$page_id'>$page_name</a><br>";
echo "<a style='text-align:left;size:14;font-weight:bold' href='/
mypage.php/".$page_id."'>".$page_name."</a><br>";
When I come across the above code in line 1, I have been changing it
to what you see in line 2 for no other reason than it delineates out
better in BBEdit. Is this just a preference choice or is one method
better than the other?

Neither.
My advice, take all the style elements out of the anchor tag.
echo("<a href='/mypage.php/$page_id'>$page_name</a>");
Even the '<br>' can be (perhaps should be) handled by css.
Cheers,
tedd

As far as I know it's just preference. Your choice of editor could
influence your decision; one form might be given nicer highlighting.

This not a PHP subject and should not be here.
However, styles should be in the style block or better in the styles CSS file.
Spend some time learning about CSS3 and modern techniques.

With respect to tedd and Al, you've misread the question: the important
PHP-related bit is about whether to embed variables in double-quoted strings or
to concatenate them. These are only two of the options, and each has it's pros
and cons. There has been (some time ago) plenty of discussion on this list about
this sort of thing, including (ISTR) a timed test of the performance
implications of various forms - that only really matters in big loops, of course...
Horses for courses. I use whatever I feel like at the time, and mix various
styles, as long as it's readable!
Cheers
Pete

I agree with Peter here. I would bet that the string with embedded
variables is parsed once when the file is loaded and turned into the same
bytecode as the second form.
If you are going to use the second style above, I would at least switch the
quotes around so you can use the double-quotes in the HTML as that to me
reads nicer and avoids the minor cost of scanning the string for embedded
code. I also put spaces around the dots to make the variable concatenation
easier to spot when skimming it.
echo '<a style="text-align:left;size:**14;font-weight:bold"
href="/mypage.php/' . $page_id . '">' . $page_name . '</a><br>';

I think you may have missed the question. The OP was asking whether:
"text $var text"
or
"text ".$var." text"
was preferrable.
For me, I tend to use the first unless the second makes things clearer
where they need to be. Syntax hilighing can easily be one of those
times.

href="/mypage.php/' . $page_id . '">' . $page_name .'</a><br>';
+1 on the use of single quotes instead of double quotes. With a bytecode
cache it's not really going to make a lick of difference, but using
double quotes for HTML seems far more palatable to me. I too like to
pull the variable out into code space. I also like to format my
attributes for easy reading and commenting:
echo '<a'
.' style="text-align:left;size:**14;font-weight:bold"'
.' href="/mypage.php/'.$page_id.'"'
.'>'
.$page_name
.'</a>'
.'<br />';
Although, I usually only do the above for tags that have lots of
attributes. Otherwise the following is more likely:
echo '<div class="some-class">'
.'Something something'
.'</div>';
As I said before though, a bytecode cache with any degree of
optimization "should" make any particular style have zero impact on
runtime (beyond original parse) by optimizing the strings into a minimal
set of operations. For instance 'foo'.'fee' would be coverted to
'foofee' by the bytecode engine.
Cheers,
Rob.

The key thing to remember here is that this is a preference and not a
performance thing.

I prefer sending arguments to the echo language construct (note, if you
send more than one argument, you can't use parentheses.) I perceive this
usage to be a clean presentation of the code's intent, easy to use in most
IDE's, and it's very fast relative to the other options:
echo "<a style='text-align:left;size:**14;font-weight:bold'
href='/mypage.php/$page_id'>$**page_name</a><br>";
echo "<a style='text-align:left;size:**14;font-weight:bold'
href='/mypage.php/".$page_id."**'>".$page_name."</a><br>";
echo "<a style='text-align:left;size:**14;font-weight:bold'
href='/mypage.php/", $page_id, "'>", $**page_name, "</a><br>";
And, for longer lines, I'll often break it up into separate lines by
argument like below:
echo
"<a style='text-align:left;size:**14;font-weight:bold'
href='/mypage.php/",
$page_id,
"'>",
$**page_name,
"</a><br>";
That all said, I don't change code that uses another convention, as I think
it's most beneficial to stay with the established conventions in any
codebase (unless you're establishing a new convention and refactoring the
entire code base.) This is just my general preference, and I don't believe
there is consensus as to the most appropriate.

Adam,
You are very correct, the last discussions and testing of theories
caused my head to hurt!!!
Neither side gained ground in testing or discussion.
Having said that to me it is a preference only and not a performance
enhancing or degrading factor in syntax.

Assuming you want to make things unique based on the "contact_first_name" field,
how would you decide which record to keep? The first one you run in to, the
last one you come across, or some other criteria?
