Know any slick ways to build a string from array?

[D. Alvarado]

Hi, I have this arr

$months = array("January" , "February", "March", "April", "May",
"June", "July", "August", "September" , "October", "November",
"December") ;

and I would like to take this array and build a string of the form

"<option value=\"1\">Jan uary</option>\n<optio n
value=\"2\">Feb ruary</option>\n<optio n value=\"3\">Mar ch</option> ...
December</option>"

Does anyone know a slick way to get to the above string from the given
array? I'm using PHP 4.

Thanks, - Dave

Yes, I know of several. And they are all in the fine manual, which you
should read offcourse.

how about:
$str='prepend'. join('glue', $arr).'append';

But more readable might be: http://php.net/foreach (second code)

Ehhh, forget the join, read the 3rd example of the foreach url.

Using the standard way usually works best. It might not be extremely
slick, but four lines is not to much. Code has not been tested.

$months = array("January" , "February", "March", "April", "May",
"June", "July", "August", "September" , "October", "November",
"December") ;

$size = sizeof($months) ;
for($i = 0; $i < $size; $i++) {
$str .= "<option value=\"" . ($i + 1) . "\">" . $months[$i] .
"</option>\n";
}

$string = "";
foreach ($months AS $key => $month) {
$string .= "<option value=\"$key\"> $month</option>\n";
}

$string now contains exactly what you had before. Is that slick enough?

I noticed that Message-ID:
<29************ *************@p osting.google.c om> from harryman100
contained the following:

$string = "";
foreach ($months AS $key => $month) {
$string .= "<option value=\"$key\"> $month</option>\n";
}

Slick, but I prefer this (untested)..

if(isset($_POST['month']) {$k=$_POST['month'];} else {$k="";}

$string = "<select name="month">";
foreach ($months AS $key => $month) {
if($key==$k){$s elected="select ed";} else{$selected= "";}
$string .= "<option value=\"$key\" $selected>$mont h</option>\n";
}
$string.="</select>";

Is one str_replace faster than 12 if's? If so, then:
$string = "<select name="month">";

foreach ($months AS $key => $month) {
$string .= "<option value=\"$key\" $selected>$mont h</option>\n";
}

$string.="</select>";

if(isset($_POST['month']) {
$k=$_POST['month'];
$string = str_replace("\$ k\">","\"$k\" selected>", $string);
}

Cool, thanks Gary. :-)

I'm running a basic PHP course now and, as I tell my students, there is
always more than one way to do it . :-)

Actually, thinking about this, how many comparisons does a string
replace have to do?

Anyone know the definitive answer? (to save me running tests,:-)
