How to strip a sentence just keep letters, numbers, spaces

Question

I have a lot of sentences that need to be cleaned up from all the special characters and punctuations (I want to keep just the letters and numbers and spaces), for example:

$string = "TB Avrupa ve Türkiye'nin en iyi oranlari ile Lider Bahis Sitesi!!";
$final_title = preg_replace('/[^a-z]+/i', '', $string); 

This remove everything (with spaces) I need to keep spaces can i add anything to the previous line to achieve this ??

Expected output :

TB Avrupa ve Türkiyenin en iyi oranlari ile Lider Bahis Sitesi

I want to keep just the letters and numbers and spaces

You can use this regex to remove everything other than english letters, digits and spaces:

preg_replace('/[^a-z\d ]+/i', '', $string);
