Here I am going to share how to remove the last comma in a string by using php function. The rtrim() function will helps you to remove whitespaces or other predefined character from the right side of a string.
|charlist||Optional. Specifies which characters to remove from the string. If omitted, all of the following characters are removed:
|string||Required. Specifies the string to check|
$str = "1,2,3,4,5,";
The rtrim() function removes whitespace characters from the right side of a string.
- ltrim() – Removes whitespace or other predefined characters from the left side of a string.
- trim() – In both sides of a string, removes whitespace or other predefined characters.
