Question

What is best way to convert csv into string ?

There is csv file.txt which is read into variable with file_get_contents() like 1,2,3,4,5 and must be turned into 12345.I could explode it into array and then combine it but maybe there is more efficent way to do it ?

Answer 1

If you need just 12345 from 1,2,3,4,5 do this:

$string = str_replace(",","", file_get_contents("file.txt"));
