#20893 [Opn]: Strings as Arrays...

ID: 20893 User updated by: davey@its-explosive.net Reported By: davey@its-explosive.net Status: Open Bug Type: Feature/Change Request Operating System: All PHP Version: 4.3.0RC2 New Comment: small code correction: $string = "foo"; foreach ($string as $i) { echo $i ."<br />\n"; } Previous Comments: ------------------------------------------------------------------------ [2002-12-08 20:56:13] davey@its-explosive.net This is probably a strange feature request, but I think it should be given a lot of thought, if it has not done so already. The request is this: strings should be treated as arrays of characters (which they are) when given as the arguement for functions which work on arrays. so for example: function foo ($chr) { echo $chr . "<br />\n"; } $string = "bar"; array_walk($string,foo); would give the result: b a r Also, to be able to do this with strings: $string = "fo"; $string{} = "o"; so that $string == "foo" == TRUE Also, another thing that comes up often, is when trying to do this: $string = "foo"; foreach ($string as $i) { echo $string ."<br />\n"; } does not work, and you have to do: $string = "foo"; for($i = 0;$i <= strlen($string);$i++) { echo $string{$i} ."<br />\n"; } like I said, give this some thought, perhaps toss it around on php-dev etc.. - Davey ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=20893&edit=1
