Turn a string into an array

$value: String to be separated into elements in the array

$delimiter: Character to use for separation

Array of elements

<pre><?
  $mylist="one,two,three,four";
  $myarray=explode($mylist,",");
  print_r($myarray);
?></pre>

The above example will output:

[$myarray] = Array (
(string) [0] => one
(string) [1] => two
(string) [2] => three
(string) [3] => four
) 
?></pre>

Note that if only one element is present (without the separator character) then a value of -1 will be returned. This differs from the PHP implementation.

<pre><?
  $mylist="one";
  $myarray=explode($mylist,",");
 
  // the fix for a single parameter is to use is_array
  if (!is_array($myarray)) {
    $myarray=array($mylist);
  }
  print_r($myarray)
?></pre>

implode() - Turn an array into a string

print_r() - Dump the contents of an array to the current output

sizeof() - Return the number of elements in an array

uPHP Variable Types and Limits

Note that there is an important difference in the parameter order between mainline PHP and Wattmon uPHP. In the mainline PHP function the delimiter comes first, but in uPHP the string to be exploded comes first:

PHP explode(delimiter,string)

uPHP explode(string,delimiter)

Wattmon uPHP's parameter order is easier to remember and more consistent: The delimiter parameter comes last in both explode() and implode().
