Listing 2.19. Using the explode() Function

<?php

    $input_string = "John Coggeshall, Max Smith, Mary Johnston";

    $pieces = explode(",", $input_string);

    echo "Names in List: <BR/>\n";
    foreach($pieces as $name) {
        echo trim($name) . "<BR/>\n";
    }

?>

Conversely, PHP also provides a function that will take all of the individual elements within an array and create a string from them. This function is the implode() function and has the following syntax:

implode($glue, $pieces);

$glue is the string used to "glue" each element of the array specified by $pieces together. uses this function to re-create our original string after it has been exploded:

Listing 2.20. Using the implode() Function

<?php

    $input_array = array("John Coggeshall",
                         "Max Smith",
                         "Mary Johnston");

    $orig_string  = implode(", ", $input_array);

?>
