Read .csv file and display it on input boxes.

Sir,

can you help me how read the content of a .csv file.

The user will input the Payroll ID, then if found, it will display on the input boxes.

for example: payroll.csv

1st column: Payroll Id 2nd column: Payee 3rd column: Particulars 4th column: Amount

(inside the csv file) 123456,JOHN DELA CRUZ,Salary for the month July 2025,15000.00

Thank's in advance sir...
