如何更优雅的删除数组元素

Question

php//类Python的remove
functionremove($arr,$value)
{
returnarray_values(array_diff($arr,array($value)));
}
var_dump(remove([1,2,3],3));//[1,2]

Answer 1

phpfunctionremove($arr,$value){array_splice($arr,array_search($value,$arr),1);return$arr;}print_r(remove([1,2,3],3));

Answer 2

上面的答案只支持数字索引，参考下面方案：functionremove($arr,$value){returnarray_diff($arr,array($value));}var_dump(remove([1,2,3],3));//[1,2]var_dump(remove(['a'=>1,'b'=>2,'c'=>3],3));//['a'=>1,'b'=>2]
