codeigniter $this->dbutil->csv_from_result ignore last delimiter

问题

I am using the following function to export to CSV.

$this->dbutil->csv_from_result()

Unfortunately at the end of the line it prints delimiter, When I use CSV to import data again it takes it as a field with out key. example are here:

"id", "time", "name",

"1", "1400000000", "John",

"2", "1400000000", "Matt",

Wondering if anybody can help with this.

回答1:

You can simply use

rtrim($string, ","); // this will strip the comma from the end of the string

Example :

$string = "abc" ; 

echo rtrim( $string , "c") ; 

It will echo ab
