To do so, you need to use the same array submission syntax in the HTML form as you do with multiple selects and checkboxes: </p> <p class="para"> <div class="example"> <p><b>Example #1 Uploading multiple files</b></p> <div class="example-contents"><div class="cdata"><pre><form action="file-upload.php" method="post" enctype="multipart/form-data"> Send these files:<br /> <input name="userfile[]" type="file" /><br /> <input name="userfile[]" type="file" /><br /> <input type="submit" value="Send files" /></form></pre></div> </div> </div> </p> <p class="simpara"> When the above form is submitted, the arrays <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']</a></var>, <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['name']</a></var>, and <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['size']</a></var> will be initialized (as well as in <var class="varname">$HTTP_POST_FILES</var> for PHP versions prior to 4.1.0). When <a href="ini.core.html#ini.register-globals" class="link">register_globals</a> is on, globals for uploaded files are also initialized. Each of these will be a numerically indexed array of the appropriate values for the submitted files. </p> <p class="simpara"> For instance, assume that the filenames <var class="filename">/home/test/review.html</var> and <var class="filename">/home/test/xwp.out</var> are submitted. In this case, <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['name'][0]</a></var> would contain the value <var class="filename">review.html</var>, and <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['name'][1]</a></var> would contain the value <var class="filename">xwp.out</var>. Similarly, <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['size'][0]</a></var> would contain <var class="filename">review.html</var>'s file size, and so forth. </p> <p class="simpara"> <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['name'][0]</a></var>, <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['tmp_name'][0]</a></var>, <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['size'][0]</a></var>, and <var class="varname"><a href="reserved.variables.files.html" class="classname">$_FILES['userfile']['type'][0]</a></var> are also set. </p> </div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="features.file-upload.common-pitfalls.html">Common Pitfalls</a></div> <div class="next" style="text-align: right; float: right;"><a href="features.file-upload.put-method.html">PUT method support</a></div> <div class="up"><a href="features.file-upload.html">Handling file uploads</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>⌨️ 快捷键说明
