How to Delete Double Quotes in a String in Perl
A string, in the Perl programming language, can contain any alphanumeric or special characters. If passing the string to another program, such as a database, you may need to remove special characters, including any double quotes. Removing double quotes also ensures that any user created strings are in the correct form. The Perl "tr" -- or transliteration -- function is used to strip the double quotes from a string. The "tr" function can be used to strip any other character from a string, also.
