I have tried many different ways but im not able to unset a variable from an array. I started with a string and exploded it to an array, now i want to remove Bill. Im i missing some thing? I have visited php.net and i, still stuck...
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<?php
$names = "Harry George Bill David Sam Jimmy";
$Allname = explode(" ",$names);
unset($Allname['Bill']);
sort($Allname);
$together = implode("," ,$Allname);
echo "$together";
?>
</body>
</html>

That is because ['Bill'] is the value of the array entry, not the index. What you want to do is
unset($Allname[2]); //Bill is #3 in the list and the array starts at 0.
or see this question for a more detailed and better answer :
PHP array delete by value (not key)

Because unset expect a key and not a value.
Bill is your value.
unset($Allname[2])
after your explode the array looks like:
array (
0 => 'Harry',
1 => 'George',
2 => 'Bill',
...
)
