The now very old North Star BASIC had a wonderful feature that I'd love to see in PHP, which was the ability to access strings using subscripts, rather like subscripting into an array, except even better since it allowed ranges to be subscripted just as easily as single characters in the strings. Examples: $string = "My String"; echo $string[5]; // returns "r" echo $string[0,]; // returns "My String" echo $string[3,5]; // returns "Str" echo $string[,3]; // returns "My S" PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

Already supported by {} and substr. DerickThank you. I know about substr() -- which is rather cumbersome compared with the notation I suggested -- but I don't know what you mean by {}. I cannot find this notation explainined in the PHP Manual (at least not in the pages about array functions, about the array type, nor in the pages about operators). Where is {} usage described? --HaigEKOoops. Getting confused about my posts (arrays versus strings). OK, I've found the very brief comments on "String access by character" -- that is, using {} to reference characters within strings -- documented near the end of http://www.php.net/manual/en/language.types.string.php in the PHP Manual. As described this gets the caller a single charecter. A nice enhancement would be to let the syntax also support ranges, by accomodating an optional second argument, length. Examples: $string = "abcde"; echo $string{1,3}; // To get "bcd" -- offset 1, length 3 But then you'd have to think about how to handle negative values, blah, blah, blah. I know, I know... You're going to bogus this because it's not likely to ever get implemented. Never mind. You might think about listing the {} operators (and the [], ->, and & operators, too) in the operators section of the manual, however, to make it easier for people to find out about them in the future. --HaigEK
