    Exclamation Can not use array

    I'm learning PHP by reading book but I've problem with array.
    I try similar code with book like this

    <?php
    $name[]="Gillbate";
    $name[]="alonso";
    $name[]="Hernandez";
    foreach($name, as $currentvalue){
    echo $currentvalue};
    ?>

    and this

    <?php
    $name[]="Gillbate";
    $name[]="alonso";
    $name[]="Hernandez";
    sort($name);
    print_r($name);
    ?>

    but they did not work.
    What is my problem?

    Syntax-wise, there is not error in the 2nd part. In the first part you have a comma in the foreach() arguments which should not be there, and closing "}" needs to come after the ";".

    PHP Code:
    $name[] = "Gillbate";
    $name[] = "alonso";
    $name[] = "Hernandez";
    foreach(
    $name as $currentvalue) {
       echo 
    $currentvalue;

    Cosmetically, the output will all be "scrunched" together since there is no HTML formatting applied to it.

    try this:
    PHP Code:
    <?php
    function print_pre($array) {
     echo 
    '<pre>';
     
    print_r($array);
     echo 
    '</pre>';
    }

    $name = array('Gillbate''alonso''Hernandez');
    print_pre($name);
    ?>

    This is that out put

    '; print_r($array); echo ''; } $name = array('Gillbate', 'alonso', 'Hernandez'); print_pre($name); ?>

    Is it ok?
    Then, how to sort them?

    Ahhh I found my problem!
    The code above give this

    Array
    (
    [0] => Gillbate
    [1] => alonso
    [2] => Hernandez
    )

    My problem is open that file directly instead though http://localhost
    Thank you everyone!

    output should be
    Code:
    Array
    (
        [0] => Gillbate
        [1] => alonso
        [2] => Hernandez
    )
    i think the error is somwhere else on your page
