Check if name exists in database (firstname lastname) - mysql

Question

I have a database with a table that contains names, some examples in the column of name:
"John Doe"
"Kevin De Bruyne"
So you'll notice that a name contains multiple words.
I also got a spreadsheet with a list of names, this is there structure:
"DOE John"
"DE BRUYNE Kevin"
(last names in caps and in front of first name)
My question is how i can write a query that checks if the name in my spreadsheet is already in the database.
I tried it with some basic queries but i couldn't figure it out so i think i'll need regular expressions to split the words? How can I do this?
This is what i have to split the words, how can i build the query? Thank you!
(\b[^\s]+\b) (splits "My name is Onovar" into "My","name","is" and "Onovar")
*Database structure:
Database name: mydb
table: people
column: name
So i need something like: If 'name from spreadsheet' does not exist in table people, insert 'name of spreadsheat' into table people*

Answer 1

You can do it like this.
$array = explode(" ", $string);
$names = implode(",", $array);
$query = "SELECT * FROM persons WHERE id IN ($names)";
then you run the query using PDO or mysqli.
EDIT
missread the question. Above solution uses php
What you realy need is all names in a comma seperated list, then you could use this query
"SELECT * FROM persons WHERE id IN ($names)"
where $name would be your comma separated list.

Answer 2

Ok, I found it.
So i put my data from my excel in an array.
$array = ["name1 firstname1","name2 firstname2",...];
i go trough every element, split the words (space)
foreach ($array as $element){
$subex = explode(' ', $element);
then I copy the last element to the front
array_unshift($subex , end($subex));
and delete the last part so i have this array: "firstname,name"
array_pop($subex);
next, i break the array so i get a string like this: "firstname name"
$naam = implode(' ', $subex);
after that i make everything lowercase
$low = strtolower($naam);
except the first letters of each words, they have to be caps
$up = ucwords($low);
after that i create my myqsl query that skips doubles and adds new ones
echo 'INSERT IGNORE INTO politici
SET naam = "'.$up.'",
partij_id = 23;';
echo '<br />';
}
And i had to be sure that every name column is unique.
