I've been handling this problem for too long and i am not close to finding any solution
My current problem is that: A line should not exceed more than 18 Length. Alphabet Letters - are considered 2 length. Special Characters such as '&', '(space)' , '(',')','[',']' are considered 1 length. Special characters are only limited to those.
The special case is that if the word length is more than 9 and it has a special character such as '&' it would create a newline and it would look like this The letters are stored in an array called
products = {'any&letter','any&body'};
Example : any&letter :
any = 6
&letter = 15 //new line
Example : any&body : any&body = 15 no new line
here is my current unfinished code but what i observed is that it has too many if statements and foreach that it may impact performance. Is there anyway i can reduce the number of foreach and if in my code?
$uniqueChar = [' ', '(', '（', '&', '【', '】', ')', '）'];
