如何将数组的首字母大写值转换为小写

Question

I have a form

Name : i.e in form (name = "detail[name]")

Address : i.e in form (name = "detail[address]")

Email : i.e in form (name = "detail[email]")

I fetched the data as follows in php:

$data = array_map('ucwords', $_POST['detail']);

I got all the values with capitalized first letter in my database after using insert query

Then I have realized that email should not be in caps so I thought of converting it to lowercase while making sure other values remains constant

And I failed ... so anyone interested to help me is most welcomed :D

Thanks in advance

Simple: PHP's strtolower function.

$lower = strtolower($value)
