// delimiters include colon (:), vertical bar (|), and comma (,)
$tokens = ":|,";
$tokenized = strtok($info, $tokens);
while ($tokenized) :
echo "Element = $tokenized<br>";
$tokenized = strtok ($tokens);
endwhile;
?>
strtok.php
<?php
$info = "this:is|a,test.";
$tokens = ":|,";
$tokenized = strtok($info, $tokens);
while ($tokenized) {
echo "Element = $tokenized<br>";
$tokenized = strtok($tokens);
}
