Making a string from an array

ralba1998

Hey there all- been a while since I posted anything. I am having this problem with making a string from an array. The form I have has a multiple select box called sizes -
*****code******
$qrystr = "select from sizes";
$numresults= pg_exec($qrystr);
$numrows=pg_numrows($numresults);

echo" <SELECT SIZE=5 NAME=size[] MULTIPLE>";

for ($i =0; $i < $numrows; $i++) {

 $id = pg_result($numresults,$i,0);
 $size = pg_result($numresults,$i,1);

echo "<OPTION VALUE=$id>$size</OPTION>\n";

}

echo "</SELECT>";                    
		?>

*************end code

when I have selected the appropriate sizes - I then have an array called sizes -
what i want to do it index the array but then make another variable have the value of that array as a string -

in essence what I want to achieve is

$sizes ="$size[1]+$size[2]"; etc.

However, since I have no idea how many boxes the user selected, I did the following -

this is the code that executes when posted --

*******code*********

for ($i=0; $i < count($size); $i++) {

	$sizes += "$size[$i]";
	echo $sizes, "|";

	}

************end code

the result I get is

26660|53321|79983|

Hmm what I want outputed is

2660|2661|2663 etc.

then this string would be inserted into my size colum of the db - and later exploded to show a list of sizing options..

Could you please advise what I have to do to make this work..

I have been banging my head for hours on something that should be relatively easy..

u can use the join() function

eg:
$str=join("|",$sizes);

u will get the desired result in $str

good luck

Thanks so much. Was trying to use implode like

$allsizes = implode("$sizes", "|");

But I kept getting an error.. I was looking for a join function. but could not find it online. Well thanks. I hate when something so easy seems so hard..
