array_intersect_uassoc() 带索引检查计算数组的交集，并用回调函数比较索引

【功能】
         该函数将返回一个数组，
         该数组包含了所有在array1中但是不在其他任何参数数组中的值。
         注意和array_intersect()函数不同的是键名也用于比较。
【使用范围】
         php5.
【使用】
         array array_intersect_assoc( array array1, array array2[,array...,callback key_compare_func] )
         array1/必需/数组1
         array2/必需/比较的数组最少得有一个
         array.../可选/用来比较的数组
         key_compare_func.../可选/为用户提供作为比较标准的回调函数
【示例】
[php]
//分别定义两个数组
$array1 = array( "blue" => 6, "red" => 2, "green" => 3, "purple" => 4 );
$array2 = array( "green"=>5 , "blue" => 6, "yellow" => 7, "cyan" => 8 );
print_r( array_intersect_uassoc( $array1, $array2, "strcasecmp" ) );
/*
Array
(
    [blue] => 6
)
*/
