Can't get array_walk to show changes to array.

[Jessica]

I have tried both:

array_walk(&$files, 'htmlentities');
array_walk($files, 'htmlentities');

 

Using PHP5

 

Nothing changes, it still prints & instead of &

Do I have to wrap htmlentities in a in a custom function or am I doing something wrong?

 

EDIT:

I tried wrapping it in a function and no change.

$h = create_function('$txt', 'return htmlentities($txt);');
array_walk(&$files, $h);
print_r($files);

 

Array

(

    [28] => panels/DC_air & space #2.jpg

    [29] => panels/DC_air & space #3.jpg

    [30] => panels/DC_air & space.jpg

)

<?php

$array = array("d" => "lemon", "a" => "<br>");
function alter(&$item1, $key){
    $item1 =  htmlentities($item1);
}
array_walk($array, 'alter');
print_r($$array);
?>

maybe

You have an extra $ in there, but after I removed it it still didn't work.

Still got:

    [28] => panels/DC_air & space #2.jpg

    [29] => panels/DC_air & space #3.jpg

    [30] => panels/DC_air & space.jpg

I think your problem is that htmlentities doesn't change the string it returns it. You aply the function to every member in the array, but the function doesn't change anything.

This works:

 

<?php

$arr = array('panels/DC_air & space #2.jpg', 'panels/DC_air & space #3.jpg', 'panels/DC_air & space.jpg');

function alter(&$arr_item){
    $arr_item = htmlentities($arr_item);
}

array_walk($arr, 'alter');
print_r($arr);
?>
