[PHP] another simple array question

2005-11-18 Thread cybermalandro cybermalandro 
I have an array with indexes 0 to 4 and I want to delete an element of the
array if the index is equals 4. I want to delete the variable key and value.
What is the best way to do so?

foreach ($values as $key = $val){

if ($key == 0) {
//
}
if ($key == 3) {
//
}
if ($key == 4) {
//delete value from array

}
}

Thanks!

if (isset($values[4])
unset($values[4]);

You may want to use array_key_exists instead of isset. isset will  
return false in the value for the array is NULL. Basically isset will  
tell you if there is a value set for the array key, whereas  
array_key_exists will tell you if the key exists or not, which is  
what you want.
