eval ?!

[toshog]

hi all..

why is this not working

$eval_code = "\$myrow['".$sort_on."']";

print eval($eval_code).'<br>';

i get:
arse error: parse error in /path/to/file/file.php(583) : eval()'d code on line 1

$eval_code = "\$myrow['".$sort_on."']";

echo eval($eval_code).'<br>';

😕 🙂

neither print nor echo work?! why is that?

this is more or less the code:

print $eval_code = "\$myrow['".$sort_on."']";

// this above prints fine....

while($myrow = mysql_fetch_array($result)) {
<b>'.eval($eval_code).'</b>
}

for this i get the warning posted above...
??!?!??

i'm looking at it... that's where i first went... doesn't work anyway...
please somebody explain why this code doesn't work...

thanks...

i even did this - which doesn't make sense but here it is:

function doEval($eval_code) {
return $m = eval($eval_code);
}

while($myrow = mysql_fetch_array($result)) {
<b>'.doEval($eval_code).'</b>
}

same result...

nobody knows why this doesn't work?
any gurus on this board?

I don't see why you need eval, why can't you jest do
echo $myrow[$sort_on];
That is valid php, I think why your eval statement isn't working is that it's not complete. An eval'd statement must be completely self contained. So if you wanted to do it (even though it shouldn't be necesary),
eval('$eval_code=$myrow["'.$sort_on.'"];');
echo $eval_code.'<br />';
see?
