消除表数据空间

Question

My column 'email' is auto filled by columns 'firstname'.'lastname' eg: 'John' 'Doe' ------> john.doe@example, but some people have multiple first names like: 'John Michael' 'Doe' -------> john michael.doe@example, how do I close that space in the first name?

Here is the code for that specific row:

<td> <?=strtolower($row['fname'])?>.<?=strtolower($row['lname'])?‌​>@cubao.sti.edu </td>

Answer 1

试试这个： str_replace([' '], [''], $formValues['firstname']).$formValues['lastname'])

Answer 2

Elimination of white space :

$clean_data = preg_replace('#[^a-z0-9]#i', '', $true_value_got_from_user);

In this case you can put $first_name in preg replace and you will get clean data as output

Additionally : This will also replace unwanted data like special characters and anything else than alphabets and special characters like (. , " " [] {} etc. ) which are not really in first name.

If you ever wanted that first name should not contain numeric like 0-9 then delete 0-9 statement and your output will be a clean alphabet string.
