easy variable change

[lvennard]

I cant remeber how to do this but i've done it before in PHP.

I want to take off the last charater of a value, like the perl chomp/chop function.

$a = 75%;
$rawvalue = rtrim ($a, "%"

NOW $rawvalue should equal "75" right? but it doesnt work.

how do I chop off the last character of the variable?

 

[sleipnir214]

$rawvalue = substr ($a, 0, -1)

should do it (

I'm guessing it's some silly typo or some such, maybe post your actual code and we can all look, because you have it exactly right. In fact, below I've cut and pasted a script which works exactly as you described... I just typed in what you posted above.

<?

$a = &quot;75%&quot;;
$raw = rtrim($a, &quot;%&quot;

echo $raw;
?>

note that the first script does not have the quotes around the percent sign... Bastien

here is the actual code.
$procidle ends up as a ##% value

echo &quot;<tr><td>\n&quot;;
echo &quot;<font size=$serverinfofont>\n&quot;;
echo &quot;Processor Usage:  \n&quot;;
$procidle = `/bin/sysinfo --system | grep &quot;System load&quot; | awk '{print $12 }'`;
$checkprochigh = rtrim ($procidle, &quot;%&quot;
$prockinuse = (100-$checkprochigh);
//echo &quot;$procinuse\n&quot;;
echo &quot;$checkprochigh&quot;;
if ($checkprochigh >= 90) {
echo &quot; \n&quot;;
echo &quot;<a href=\&quot;$whysohighprocurl\&quot; target=right>\n&quot;;
echo &quot;why so high?</a>\n&quot;;
}
echo &quot;</font>\n&quot;;
echo &quot;</td></tr>\n&quot;;

i had $procuse comment out so that it would still look like it was working.

 

[lvennard]

$rawvalue = substr ($a, 0, -1)

worked great!

Thanks Everyone!!!!
