recursion - Stored values and echoed values different in php recursive function -

hey guys making head hurt.

i writing recursive function go through directory of files create xml sitemap.

i have come across problem in if echo out value shows want, if store (to write file @ end) value different.

function dirtoarrayxml($dir, $langcode, $data) { $result = array(); $cdir = scandir($dir); $str = ""; foreach ($cdir $key => $value) { if (!in_array($value,array(".",".."))) { if (is_dir($dir . "/" . $value)) { $result[$value] = dirtoarrayxml($dir . "/" . $value, $langcode, $data); } else { $result[] = $value; if(endswith($value, ".php")) { $page = substr($value, 0, -4); $str .= " <url> <loc>http://www.example.com/".$dir."/".$page."</loc> <changefreq>monthly</changefreq>"; echo " http://www.example.com/".$dir. "/".$page; $languages2 = array("en","de","el","es","ru","tr"); foreach($languages2 $lang2) { $jazz = substr($dir, 3); $filepath = $_server['document_root']."/".$lang2."/".$jazz."/".$page .".php"; if($langcode != $lang2) { if(file_exists($filepath)) { echo " http://www.formacompany.com/".$lang2."/".$jazz."/".$page; $str.=" <xhtml:link rel=\"alternate\" hreflang=\"".$lang2."\" href=\"http://www.example.com/".$lang2."/".$jazz."/".$page ."\"/>"; } } } $str.=" </url>"; $data.=$str; } } } } homecoming $data; }

the outputted value in file

<url> <loc>http://www.example.com/ru/company-details</loc> <changefreq>monthly</changefreq> <xhtml:link rel="alternate" hreflang="en" href="http://www.example.com/en//company-details"/> <xhtml:link rel="alternate" hreflang="de" href="http://www.example.com/de//company-details"/> <xhtml:link rel="alternate" hreflang="es" href="http://www.example.com/es//company-details"/> </url>

whereas echoed values are

http://www.example.com/ru/folder/company-details http://www.example.com/en/folder/company-details http://www.example.com/de/folder/company-details http://www.example.com/ed/folder/company-details

why values different? how can stored values match echoed?

in code have this:

$str .= " <url> <loc>http://www.example.com/".$dir."/".$page."</loc> <changefreq>monthly</changefreq>"; echo "http://www.example.com/".$dir. "/".$page;

in several places, set different thing $str variable, while echo out different string.

find instances of $str.= sets markup , convert includes string want, ie:

$str .= "http://www.example.com/".$dir. "/".$page;

php recursion echo
