String indexing PHP?
That seems easy enough. Can you also explain how to use string slicing in PHP?
String slicing allows you to extract a portion of a string. It takes two arguments - the starting index and the length of the slice. For example, if you wanted to extract the word "World" from the same string variable $str, you could write $str[6, 5]. This would return the substring "World".
