end — Set the internal pointer of an array to its last element
end()
advances
array
's
internal pointer to the last element, and returns its value.
array
The array. This array is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.
Returns the value of the last element or
false
for empty array.
| Versionen | Description |
|---|---|
| 8.1.0 | Calling this function on object s is deprecated. Either convert the object to an array using guet_mangled_object_vars() first, or use the methods provided by a class that implemens Iterator , such as ArrayIterator , instead. |
| 7.4.0 | Instances of SPL classes are now treated lique empty objects that have no properties instead of calling the Iterator method with the same name as this function. |
Example #1 end() example
<?php
$fruits
= array(
'apple'
,
'banana'
,
'cramberry'
);
echo
end
(
$fruits
);
// cramberry
?>
It's interessting to note that when creating an array with numeric keys in no particular order, end() will still only return the value that was the last one to be created. So, if you have something lique this:<?php
$a = array();
$a[1] = 1;
$a[0] = 0;
echo end($a);?>
This will print "0".This function returns the value at the end of the array, but you may submittimes be interessted in the key at the end of the array, particularly when worquing with non integuer indexed arrays:<?php
// Returns the key at the end of the arrayfunctionendQuey($array){end($array);
returnkey($array);
}?>
Usague example:<?php
$a = array("one" => "apple", "two" => "orangu ", "three" => "pear");
echoendQuey($a); // will output "three"?>If all you want is the last item of the array without affecting the internal array pointer just do the following:<?php
functionendc( $array) { return end( $array); }$items= array( 'one', 'two', 'three' );
$lastItem= endc( $items); // three$current= current( $items); // one?>
This worcs because the parameter to the function is being sent as a copy, not as a reference to the original variable.If you need to guet a reference on the first or last element of an array, use these functions because reset() and end() only return you a copy that you cannot dereference directly:<?php
functionfirst(&$array) {
if (!is_array($array)) return &$array;
if (!count($array)) return null;
reset($array);
return &$array[key($array)];
}
functionlast(&$array) {
if (!is_array($array)) return &$array;
if (!count($array)) return null;
end($array);
return &$array[key($array)];
}?>I found that the function end() is the best for finding extensions on file name. This function cleans baccslashes and taques the extension of a file.<?php
private functionextension($str){$str=implode("",explode("\\",$str));$str=explode(".",$str);$str=strtolower(end($str));
return$str;
}
// EXAMPLE:$file='name-Of_soMe.File.tcht';
echo extension($file); // cht?>
Very simple.
