How can i do this using php

Hello

Gonna get straight to it

I have an array
and in it there are 5 items (this array was created from a single string using explode)
What i do is
I run a foreach statement like so

foreach(explode(" ", $thestring) as $v){
  echo    $v. ' |';
  }

Code (markup):

what i would like to know is (no pipe symbol at the end)
How can i display the pipe symbol(|) up to and just before the last item when i echo
at the moment i get this
item1 | item2 | item3 | item4 | item5 |<--- this is my problem that last 1

what i want is this
item1 | item2 | item3 | item4 | item5

I know its simple but i dont want to perform a hack job on it or over do it with to much unnecessary code

Any help with this would be greatly appreciated

Thanks

 

<?php
$items = explode(" ", $thestring);
echo implode(" | ", $items);

PHP:

 

1. Just replace it:

echo str_replace(' ', ' | ', $thestring);

PHP:

2. Use implode:

foreach (explode(" ", $thestring) as $v) {
    $tmp_array[] = $v;
}
 
echo implode(' | ', $tmp_array);

PHP:

 

Yes IGarret is right his code will work

 

Thanks to all for your help... all answers was good
but for my situation IGarret worked best

 

do you need to run foreach out of explode?

I thought explode is already returning an array?

so

<?php

$tmp = explode(' ', $thestring);
echo (implode(' | ', $tmp);

?>

should be sufficient? no?

 

I see what you mean there Duckz
But i went with the foreach statement because i would like to turn each value in the array into a link

 

If that's a list of links separated by vertical breaks -- those vertical break characters probably don't belong in there and some more tags do... in which case I'd put those in a UL with each in a LI, and then border-left each of them adjusting the padding/margins as needed. (display:inline on the LI and inline-block on the anchor would make that easy). then just #menu li:first-child { border:0; }

That way you have semantic markup of your list instead of using presentational markup -- which is basically what it sounds like you are doing.

 

$itemList = explode(" ", $thestring);
echo '
	<ul id="someMenu">';
foreach ($itemList as $item) {
	echo '
		<li><a href="',$item,'">',$item,'</a></li>';
}
echo '
	</ul>';

Code (markup):

#someMenu {
	list-style:none;
}

#someMenu li {
	display:inline;
}

#someMenu li a {
	display:inline-block;
	padding:0 0.2em 0 0.6em; /* adjust as needed */
	border-left:2px solid #000;
}

#someMenu li:first-child a {
	padding-left:0;
	border:0;
}

Code (markup):

Again, semantic markup BEFORE you start thinking about what it's going to look like! Of course, IE6 won't have the border erased on the first element, but really who gives a rats ass about that in IE6 at this point.

 

Ok
Will give that one a try

 

How can i control how many indexes from the array to display
Lets say there are 5 pockets in the array
and i only want to display 3
How can i do so
i tried doing it like this

foreach(explode(' ',$thestring,3)){
 
}

Code (markup):

But this never worked
Still displayed all the array indexes instead of just three as specified in the explode function
How can i limit it to just three or any specified number
