Gurus, Variable Function Arguments???

[eojlin]

Hi,

I have a "loop" that should pass varying arguments to variable functions. These functions have varying number of arguments that each one of them can accept.
My problem is how am I going to pass the right number of arguments to the varying functions that I have in my loop.

func_num_args() can only be called once you're already inside the function.
Is there a function in PHP that can determine the number of arguments a certain function accepts before calling that certain function?

here's a quick view of my snippet:

    // table: data
    $blnGoArray = is_array($arrFuncs);
    $strCurrShade = $this->strRowAltColour2;
    while($row = mysql_fetch_row($result)) {
      if ($blnGoArray) reset($arrFuncs);
      $strCurrShade = ($strCurrShade == $this->strRowAltColour1) ? $this->strRowAltColour2 : $this->strRowAltColour1;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$strDisplay .= "\t<tr>$strEol";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;foreach($row as $val) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$strDisplay .= "\t\t<td bgcolor=\"$strCurrShade\" align=\"CENTER\" valign=\"MIDDLE\">$strEol";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if ($blnGoArray) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$currFunc = current($arrFuncs);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;next($arrFuncs);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (function_exists($currFunc)) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$strDisplay .= "\t\t\t" . $this->setText($currFunc($val, $row)) . "$strEol";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} else {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$strDisplay .= "\t\t\t" . $this->setText($val) . "$strEol";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} else {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$strDisplay .= "\t\t\t" . $this->setText($val) . "$strEol";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$strDisplay .= "\t\t</td>$strEol";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$strDisplay .= "\t</tr>$strEol";
&nbsp;&nbsp;&nbsp;&nbsp;}

$arrfuncs is an array of string function names.
$strEol is just escape characters for end of line.
$_strRowAltColour's are just colour strings for the alternating HTML table row colours.

$this->setText() is just a function that formats your string into a HTML-Font-formatted text.

the code above works fine, it just doesn't seem right. it's messy to assume that all functions accept more than one arguments.
i need suggestions.

pass an array of arguments?

[eojlin]

yes... i already have that one in this line (part of the code snippet):

&nbsp;&nbsp;&nbsp;&nbsp;$strDisplay .= "\t\t\t" . $this->setText($currFunc($val, $row)) . "$strEol";

• $row is a vector array of the current row in a sql query result set.
• $val is the value of a certain/current row-and-column element in $row.

i need the "specific record as specific function argument" feature. it will eventually help make functions automatic and reusable with other elements in your sql query result set.
actually, the code snippet is part of a PHP object that aims to display an sql query result set in a customizable HTML-Table (something like an extension to the existing phpMyAdmin application).
