ช่วยดูโค้ดหน่อยค่ะ เป็นโค้ดที่ให้compile ภาษาจาวา ผ่านเว็บไซด์ อยากแก้ให้เป็น complie ภาษาซี

<script type="text/javascript">
function complie()
{
	document.getElementById("form1").action="fileInput.php?method=compile";
	document.getElementById("form1").submit();	
}

function run()
{
	document.getElementById("form1").action="fileInput.php?method=run";
	document.getElementById("form1").submit();	
}

</script>


<form name="form1" id="form1" method="post" action="">
  <label for="inputText"></label>
  <div align="center">
    <p>
      <textarea name="inputText" id="inputText" cols="100" rows="20" ><?php if(isset($_POST['inputText'])){print $_POST['inputText'];} ?></textarea>
    </p>
    <p>
      <label for="filename">input filename*</label>
      <input name="filename" type="text" id="filename" value="" size="20" maxlength="20">
      <br>
    (Note: if you use the file name as &quot;XXX.java&quot;, you should create your main class as &quot;XXX&quot; as well)</p>
    <p>
      <input type="button" name="button" id="button" value="Compile" onClick="complie()">
      <input type="button" name="Run" id="Run" value="Run" onClick="run()">
    </p>
  </div>
</form>

<table width="100%" border="0">
  <tr>
    <td bgcolor="#00FFFF">&nbsp;
      <div align="center">
        <?php
	if(isset($_POST['inputText']) && $_POST['filename'] !=""){
