In php, you can use the substr_replace () function to remove the second character from the string.

The substr_replace () function is a replacement function that replaces characters of a specified length, starting at a specified location.

Syntax:

Mixed substr_replace (mixed $string, mixed $replacement, mixed $start [, mixed $length])

Substr_replace () replaces the substrings qualified by the start and optional length parameters with replacement in the copy of the string string.

If start is positive, the replacement starts at the start position of the string. If the start is negative, the replacement starts at the penultimate start of the string.

If the length parameter is set and is a positive number, it indicates the length of the substring to be replaced in the string. If set to a negative number, it indicates the number of characters at the end of the substring to be replaced from the end of the string. If this parameter is not provided, it defaults to strlen (string) (the length of the string). Of course, if length is 0, then the function of this function is to insert replacement into the start location of the string.

To remove only the second character, just set start and length to 1 and replacements to the empty character "'".
