php - Number the iframes and display it -


i have piece of code reads space separated urls input string , replaces them iframe video. want insert number of iframe above each of them.

below code:

$result = $conn - > query($sql); if ($result - > num_rows > 0) {     // output data of each row     while ($row = $result - > fetch_assoc()) {         $nr = $row['nr'];         $playery = $row['player'];         $nrplayer = $nrplayer++; //old int (not used)           //////remove string iframes , replace tons spaces 1 before every url (that makes string more clear)//////         while (strpos($playery, ' ') !== false) {             $playery = str_replace(" ", "", $playery);         }         $playery = str_replace("http", " http", $playery);         $playery = str_replace('<iframewidth="420"height="315"src="', ' ', $playery);         $playery = str_replace('<iframesrc="', ' ', $playery);           ////////remove space of front , in ////////         while (mb_substr($playery, 0, 1) == " ") {             $playery = substr($playery, 1);         }         while (mb_substr($playery, 0, -1) == " ") {             echo "ok";             $playery = substr($playery, 1);         }           //////add ads on page////////         require("ads.php");          //////create iframes///////         $nrr = 1;         echo $nrr."<br><br><br> <iframe allowfullscreen='1' width='800' height='500' src='".str_replace(' ', "'></iframe> ".$nrr++." <br><br><br> <iframe  allowfullscreen='1' width='800' height='500' src='", $playery)."'>";      } }

i have got 1 row , value of string $playery is

$playery = "http://www.dailymotion.com/swf/x2t2mgd http://www.dailymotion.com/swf/x2t2ury https://drive.google.com/file/d/0b4dzuaecnhcsdlhnlurau0dbqtg/preview https://drive.google.com/file/d/0b6orwphisxtcuvpmd0rntfu3wk0/preview https://drive.google.com/file/d/0b9x5eo1ro_r9uvzzsvjucgtjbgs/preview http://mp4upload.com/embed-t9ve1iot81so.html"

with code, output this:

   1 <video>    1 <video>    1 <video>    1 <video>

however, want this:

   1 <video>    2 <video>    3 <video>    4 <video>

in php $var++/$var-- expressions executed after statement encapsulated in, $nrr not become incremented until after echo

$var = 1; echo $var++; //1 echo $var; //2
