    Need help with file upload

    Hello!
    I again need your help, just can't understand whats going on.
    Got this upload pictures form and it's having problem handling large
    files (~1.5 - 2 MB).
    Everything works fine if i just upload files, like this:

    copy ($myfile, $uploadfolder . "/" . $myfile_name);

    Everything works fine, it can process large files and everything,
    but i need to make sure that people only upload pictures, so i change
    it to this:

    $fext = strrchr($myfile _name,".");
    if($fext==".jpg " || $fext==".jpeg")
    {
    copy ($myfile, $uploadfolder . "/" . $myfile_name);
    }

    After this modification it can only process relatively small files,
    around 200-300 kb, everytime i try to upload a large file it just does
    not do anything,
    it looks like the file is being uploaded and then nothing, the file is
    not there...
    I tried setting
    set_time_limit( 0);
    but it did not change anything...
    if i check the extension it does not upload large files, if i don't -
    it does...
    Could someone help me please, thank you!

    P.S. Whats better to use, copy or move_uploaded_f ile? Or it just does
    not matter?
    Thanks a lot again!

      Maybe you have some upload limit set on your server. Check your php.ini
      file.

          Have you considered CaSe SenSITivity? I'd try something like:

          preg_match("/(jpeg|jpg)$/i", $_FILES['myfile']['name']);

              Try this

              upload.php
              --------
              <?
              /* Max filesize: */
              if($arquivo_siz e > 1024000) {
              print "<SCRIPT> alert('File cannot to be larger than 1 Mb');
              window.history. go(-1); </SCRIPT>\n";
              exit;
              }
              /* Define target dir to store uploaded files */
              if (!empty($arquiv o) and is_file($arquiv o)) {
              $caminho="/full/path/to/the/dir/";
              $caminho=$camin ho.$arquivo_nam e;
              /* Define the kind of file allowed */
              if ((eregi(".DOC$" , $arquivo_name)) || (eregi(".zip$",
              $arquivo_name)) ){
              copy($arquivo,$ caminho);
              print "<h1><center>Fi le was sent!</center></h1>";
              }
              else{
              print "<h1><center>Fi le was not sent!</center></h1>";
              print "<h2><font color='#FF0000' ><center>File type not
              allowed!</center></font></h2>";
              }
              }
              ?>

              --------
              upload.html

              <html>
              <head>
              <script language="JavaS cript">

              if (document.uploa d.arquivo.value =="") {
              alert("Arquivo para upload não informado!")
              document.upload .arquivo.focus( )
              return false
              }
              }
              //-->
              </script>
              </head>
              <body>
              <h2>Upload Simples</h2><br>
              <form name="upload" action="upload. php" method="post"
              enctype="multip art/form-data" onsubmit="retur n teste()">
              <input type="file" name="arquivo" size="60"><br>

                  Thank you so very much Carlos!
                  I still don't understand why but your version works, uploads any size i want!
                  Must be the way you check for file extension,
                  Thank you very much!
