 $HTML = "

change $all:
function Input($nama,$com, $id, $all)

 to $alldata:
function Input($nama,$com, $id, $alldata)

I tried that but the above suggestions didn't work. Still giving me a blank page. I think it is because I am breaking $HTML variable wrong. Any idea ?
Thanks

you are missing a semicolon after $j++. copy and paste this:
<?php
function Input($nama,$com, $id, $alldata)
{
	if($nama == 0){
		$com = "<font color=\"red\"> </font>";
	}
 
	$HTML ="
<HTML>
        <BODY>
        
         
                <table width='90%' border='2'> ";
$j = 0;
while($j < $alldata)
{
	$HTML .=  "
  <tr>
    <td>{$id}</td>
    <td>{$com}</td>
  </tr>";
 $j++;
}  
$HTML .= "</table>
                
        </BODY>
</HTML>";
return $HTML;
}

Did you notice the braces around the variables:
>>   <td>{$id}</td>
>>    <td>{$com}</td>

there's nothing else wrong with that function. Most likely you are not passing the parameters correctly.

>>$j = 0;
while($j < $alldata)

are you passing a numeric value for $alldata?

yes. What I am trying to do is make the rows of the data from the table. $alldata is 7 cause there are 7 records. the code below works but gives me only 1 record and I want to generate the rows for as many records are there. But when I slice the code below to incoporate WHILE statement, it fails. It doesn't let me break the variable.
Thanks
<?php
function Input($nama,$com, $id, $alldata)
{
	if($nama == 0){
		$com = "<font color=\"red\"> </font>";
	}
 
	$HTML ="
<HTML>
        <BODY>
        
         
                <table width='90%' border='2'> 
	
  <tr>
    <td>{$id}</td>
    <td>{$com}</td>
  </tr>
</table>
                
        </BODY>
</HTML>";
return $HTML;
}

you probably need $com in between the font tags. The attached code worked for me:
function Input($nama,$com, $id, $alldata)
{
	if($nama == 0){
		$com = "<font color=\"red\">$com</font>";
	}
 
	$HTML ="
<HTML>
        <BODY>
        
         
                <table width='90%' border='2'> ";
$j = 0;
while($j < $alldata)
{
	$HTML .=  "
  <tr>
    <td>{$id}</td>
    <td>{$com}</td>
  </tr>";
 $j++;
}  
$HTML .= "</table>
                
        </BODY>
</HTML>";
return $HTML;
}
 
echo Input(0,"y",3,4);
