I Have to Remove The Key of One Array Of Not Have in Another Array, Like

    /**
     * I Have This Array, With Keys
     * Name, Lastname, Date
     */
    $Array = Array( 'name' => 'Mike', 'lastname' => 'Griggs', 'date' => strftime( '%A %c' ) );
    /**
     * And The Split , Make This One Array
     */
    $Fields = 'name, lastname';
    foreach( split( ',', str_replace开发者_运维技巧( ' ', NULL, $Fields ) ) as $Index => $Field ):
             if(!array_key_exists( $Field, split( ',', str_replace( ' ', NULL, $Fields )))):
                   unset( $Array[$Field] );
             endif;
    endforeach;
    print_r( $Array );
    /**
     * i Have to Remove The Elements of $Array
     * That Not Have in $Fields, In This Case, Unset 'date' From $array
     */

But Retorning The Date Field in Array I Need to Unset The Keys Of Not Have in $Fields From Array, If Dont Have Name in Array, Return Only LastName ..

You should consider formating your questions in proper English. Mostly because users will either criticize it instead of answering it or ignore it completely.

That being said, I assume you have an array and a string with comma separated indexes. Then you want to "sanitize" your array by removing extra data.

Here's an example on how you might do that:

<?php
$array = Array( 'name' => 'Mike', 'lastname' => 'Griggs', 'date' => strftime( '%A %c' ) );
$fields = 'name, lastname';

function removeIndex($a,$f){
    $f=explode(',',$f);
    $b=array();
    foreach($f as $v){
        $v=trim($v);// only need if you have extra whitespace
        $b[$v]=$a[$v];
    }
    return $b;
}

$array=removeIndex($array,$fields);
print_r($array);
?>
