利用PHP Explode不会转储解析后的字符串

I have a database where I am storing a long string in one column. I am using two different delimiters. I am using $$ to separate the 4 inputs user can input. I am using ** to separate between each time the user enters the inputs (keep up with historical). I am pulling the data and trying to display it within my php file. Here is a portion of my code. My code is working when no ** delimiter is found (only $$ is found). However, when I enter the if statement due to finding **, my code quits printing data out. I get no errors just a blank section on my page. Do I have something set wrong in the while ($lUB < $bSize){} portion?

if ($userData[$index] != "")
 {
    if (strpos($userData[$index], '**') != false)
    {
     echo "here 0";
        $userDataB = explode("**", $userData[$index]);
        $lUB = 0;
        $bSize = count($userDataB);
        while ($lUB < $bSize)
        {
           $dataparse = explode("$$", $userDataB[$lUB]);
           echo ("<tr>");
           echo("<td>");
           echo  $dataparse[1];
           echo("</td>");
           echo("<td>");
           echo $dataparse[2];
           echo("</td>");
           echo("<td>");
           echo $dataparse[0];
           echo("</td>");
          echo("</tr>");
          unset($dataparse);
           $lUB = $lUB+1;
        }
    }
    else
    {
     echo "here 1";
        $dataparse = explode("$$", $userData[$index]);
        echo ("<tr>");
        echo("<td>");
        echo  $dataparse[1];
        echo("</td>");
        echo("<td>");
        echo $dataparse[2];
        echo("</td>");
        echo("<td>");
        echo $dataparse[0];
        echo("</td>");
       echo("</tr>");

    }
 }
 else
 {
    echo "here 2";
 }

If string is at the start of another string, strpos will return 0, which is equal to false in an if block, either you should use === operator or try to use some other function.
