如何更优雅的删除数组元素

Question

php//类Python的removefunctionremove($arr,$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]
