#26414 [Bgs->Csd]: No documentation on modifying a string by indexing and assignment

ID: 26414 Updated by: goba@php.net Reported By: stephen dot fromm at verizon dot net -Status: Bogus +Status: Closed Bug Type: Documentation problem Operating System: irrelevant PHP Version: Irrelevant New Comment: Closed, not bogus, as there was a confirmed bug and it was fixed. The manual only documented access by index and not modification... Previous Comments: ------------------------------------------------------------------------ [2003-11-25 17:01:29] ali@php.net Here: http://www.php.net/manual/en/language.types.type-juggling.php you find the behaviour documented. I'll will add a small example to the "Strings" section, so that it will be clarified and seen faster. ------------------------------------------------------------------------ [2003-11-25 16:17:20] stephen dot fromm at verizon dot net Description: ------------ The PHP documentation nowhere indicates whether it's legal to *modify* a string by accessing an individual character in the string with the index operator (curly braces) and an assignment statement, as in: $str = '0123456789'; $str{4} = 'd'; // Now $str should be '0123d56789' While it does work on my machine, I feel the behavior should be documented, as * for all I know, there may be strange side effects (given php's complex copy semantics); * using undocumented language features can result in code that doesn't age or port well; * this is a fundamental aspect of any computer language. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26414&edit=1
