Had a problem with the php-rrdtool RPM on a Centos5.x server. The RPM didn't add the file "rrdtool.ini" to the "/etc/php.d/" directory. Added the file with the following 2 lines:
; Enable rrdtool extension module
extension=rrdtool.so

restarted httpd and the module loaded.

@tarek Make sure the options that need a double dash haven't been converted into the special long dash. For instance, the first value in the opts should have two dashes in front of it.

Another question: How to display the graph on the web page?

Thanks.

@Soule You probably want to make sure that the step has two dashes in front of it and not one long dash. Depending on the day the double dashes get changed into one long dash by wordpress and make things fail.

Hello,

I've been following your fine tutorial from the start. I'm running Ubuntu server 8.04, I've installed the RRDtool extention and copied the first script you published –
but I get this error:

Create error: can't parse argument '–step'

Can you help me? For the record, i installed from ubuntu repository librrd-dev and did the rest manually, and on phpinfo() it says rrdtool 1.2x.

Cheers,

-Soule

Hi,

The extension build fine, but when i tried this example i got the following error :

Create error: can't parse argument 'net.rrd'

If anyone has an idea… seems there's something weird in the API… Something related to my versions ? RRDtool 1.3.1 and PHP 5.2.5, and i'm on a 64-bits (AMD) plateform.

Thanks for any help,
regards,

Under CentOS/64 the rrd_create() function returned "can't parse argument '\x96step'" error.

I solved it calling the function in this way:

$opts = array( chr(45).chr(45)."step", "900", chr(45).chr(45)."start", 0,

and so on.
