Php for loop array not working -

-

i'll post, hello, world

expecting

hello,6 h e l l o , world5 w o r l d

instead get

hello,6 h e l l o ,  world5

there 2nd word not spell?

$name = $_post['engname']; $convert = array_combine($letters, $jap);  function get_num_of_names($name) {     $name = explode(" ",  $name);         $name_mainlen = count($name);           for($i=0; $i <= $name_mainlen + 1; $i++) {             echo $name[$i];             $name[$i] = str_split($name[$i]);             $namelen = count($name[$i]);             echo $namelen . '<br/>';              function spellname($x, $namelen) {                 for($i=0; $i <= $namelen; $i++) {                     echo $x[$i] . '<br/>';                 }                }             spellname($name[$i], $namelen);         }   } get_num_of_names($name);

you're defining function in loop. script should implode function 'spellname' defined error, if you'd activate error reporting.

a function defined when encountered. if place in loop, defined on each iteration. since can't define 2 functions same name, script aborts fatal error.

apart that, there easier ways want do:

$str = 'hello world'; $words = explode(' ', $str); $output = array(); foreach ($words $word) {     $output[] = join('<br />', str_split($word)); } echo join('<br /><br />', $output);

or, one-liner:

echo join('<br /><br />', array_map(create_function('$a', 'return join("<br />", str_split($a));'), explode(' ', $str)));

or, shorter different approach (regards @long ears):

echo join('<br />', str_replace(' ', '', str_split($str)));

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
