How to extract values from array for printing

Question

I am new to php and trying to accomplish something that must be easy but for whatever reason I cannot find the answer through a search.

Basically I have an array that contains a few items. I want to print them out in a list but I don't want the array arrows.

Example: using print_r($_SESSION[species]); gives:

Array ( [0] => value1 [1] => value2 [2] => value3 [3] => value4 [4] => )

but I want just:

value1
value2
value3
value4

How can I achieve this? Thank you in advance.

Sounds like you want implode. And make sure you quote your array keys: $_SESSION['species']. — cmbuckley

you can iterate through an array with a loop (for, foreach, while, pick one) and print out the values. — mboldt

You can implode the array

$impl=implode("\n",$_SESSION[species]);
echo $impl

Will give you

value1
value2
value3

This will only insert newlines in HTML source. If you want html linebreaks use

implode("<br />",$tmp);

...or you could be simpler than the example above, and do a foreach

<?php

foreach($_SESSION['species'] as $value)
{
  echo $value."<br />";
}

?>

Thanks that did it. OK so how could I reverse the list. I.e. I want the last value to be at the top of the list.
