better programming

[Michael]

Hi,

A quick and most likely simply question about which is generally better
programming with PHP. Is it more proper to break out of PHP code to write
HTML, or is it ok rto do it within print() statements? Such as...

SCRENARIO A)
<?php
....code...
?>
<img src="<?=$imgsrc ?>">
<?php
....more code...
?>

SCENARIO B)
<?php
....code...
print("<img src=\"".$imgsrc ."\">");
....more code...
?>

Thanks,
Michael

It highly depends, and there is no easy answer. I usually break out of php
for large blocks, and stay inside for small bits.

However, the reason I post;
1. <?=$imgsrc?is a Bad Thing
It can work, no question about that, but always try to use a proper
<?php echo ''; ?>.

2. print("<img src=\"".$imgsrc ."\">");
Better would be either print("<img src=\"{$imgsrc} \">"); or print('<img
src="'.$imgsrc. '">');

Grtz,

Of course there is no 'best', 'best practice' or 'proper' [Hey will
posters /please/ stop asking for 'best practice'!]

Personally I _write in PHP_ and so print() everything. This gives you
the flexibility to stop hard-coding any time you please.

For example :
$address = "57 High St., Huddersfield"; // could be define()
print("You can visit us at $address Monday to Friday 9 - 5");

$address can be derived from an include/configuration file. This means
there is one more thing to go wrong at initial setup but it also means
that it can cope with moving premises AND setting up a second location
in a single place.

It also means that if you think 'objects' you can emit objectively (as
it were) rather than HTML-ing every instance.

This gets more serious when you want to mix and mingle with CSS. An
'Address' object might be used for printing postal address to a screen,
a postcode to a map URL or a company address for an invoice (using DX
for solicitors etc.).

And if you're ever thinking of internationalis ation ...

Good point:

$format['visitus'] = array(
'en' ='You can visit us at %s Monday to Friday 9 - 5',
'nl' ='U kunt ons van maandag tot vrijdag tussen 9 - 5 op %s
bezoeken.');

$lang = 'en'; //or somthing else

printf($format['visitus'][$lang],$adress);

Makes it a lot simpler to change languages then the other option.

Re: better programming

Why don't you try to separate your code from the html part completely,
e.g. with Smarty (http://smarty.php.net) ???

Good call, thought nobody would suggest this IMHO best solution for the
proposed question, where I don't mean that Smarty is the best solution,
but the idea of separating business logic from representation.

I find code easier to read if it is almost entirely PHP or almost entirely
HTML. Therefore, large blocks of static HTML with little or no dynamic
content will use html:

// php code goes here....
?>
<h1>Welcome to the Wizard!</h1>
<p>Welcome, <?=$user_id?> , to our wizard, we hope
that you will find it easy to use, and all
of that nonsense.
<?php
// ...more php code

However, if I am stringing together text that is more variables than static,
it tends to look better and be easier to read if it is a list of PHP
commands:

$row=SQL_OneRow ("Select * from customers...")
echo "Hello ".$row['user_id'];
echo ", I see you are from ".$row['city'];
echo ", and that you have ".$row['eyecolor']." eyes";
