Re: New string functions: str_startswith() and str_endswith()

Hi, Actually starts with and ends with is a very common case. I see your concerns, but I can see instantly quite a lot of places in my code where I'd use those. And I bet it'll be faster too. Many of the string functions can be replicated with one-liners using other string functions, same for array functions. I still think a very common case should be addressed natively. Regards, Stan Vassilev

For the start of the string: substr($haystack,0,strlen($needle)) == $needle And for the end of the string: substr($haystack,-strlen($needle)) == $needle For case-insensitivity, just strtolower both. Writing built-in functions for something that can be done with trivial one-liners isn't something we typically do. -Rasmus Lars Strojny wrote:

Hi Martin, first of all, thanks for you work! A few comments below. Am Samstag, den 19.07.2008, 14:55 +0200 schrieb Martin Jansen:

Attached you'll find a patch against PHP_5_3 that implements two new string functions: str_startswith(haystack, needle [, case_sensitivity])

That's in my opinion too easy to solve with strpos($haystack, $needle) === 0.

checks if haystack starts with needle. The check is performed case-insensitively, but this can be overridden by passing TRUE as the value for the third parameter. The second function str_endswith(haystack, needle [, case_sensitivity])

[...] Suffix checking is indeed a bit harder. But I'm not sure if we should introduce a function for every special case. Suffix verification often is about verifying file extensions. That could be easily solved with pathinfo() (and to make that easier, it would be more helpful to allow the engine to directly access returned arrays like pathinfo($file)['extension']). The other thing I would love to see is something I really love in Ruby: you have various ways to work with substrings[1]. For example you can do "foobar"[-3,3] == "bar" to check the suffix. That's in my opinion much easier and flexible. So -1 from me for the new string functions, but +1 for niftier variants to work with offsets.
