Today, I was working with some code related to CSV files and converting them to xml files (will talk about xml parsing and conversion later in other posts). I needed a function through which I could get a string from a string by giving a start needle and an end needle.

For example: Given a string variable like: $string = “I am a [string variable]“; and you want to fetch out everything which lies between “[" and "]“. You can use these functions given below to accomplish this task. So you will get the result as “string variable”.
