quotes - Problematik

[kahlimero]

Hallo,

Habe schon einiges mit PHP realisiert, aber momentan komm ich einfach nicht weiter vielleicht kann mir jemand einen Tipp geben.

Ich administriere einen LAMP Server habe in der php config File safe_mode aktiviert.

Nun funzt alles so wie ich (und die Webuser drauf) sich das vorstellen, aber mit ImageMagic gibts große Probleme:

$Convert_string = "/usr/bin/convert -quality 87 -antialias -scale 130x86 -sharpen 1x1 pic1.jpg pic1_converted.jpg";
system($Convert_string);
funktioniert problemlos.

$Convert_string = "/usr/bin/convert -quality 87 -antialias -scale 130x86 -sharpen 1x1 \"pic1.jpg\" \"pic1_converted.jpg\"";
system($Convert_string);
funktioniert nicht.
Die Zieldatei wird nicht erstellt und naja... Erros folgen ...

Das Problem ist dass einige fertige Skripte nach Variante 2 arbeiten die schlagen dann nat. fehl.

Kann mir da jemand helfen fleh?

I realize there "may" be some folks here that speak German, but I'm pretty sure that there is far more english speaking folks here...

Ya may wanna either get it translated for you or some other method to get better results!

My german is a little rusty, but if your second version is causing you problems, a good place to start is your string. Do you realize that you don't have to use double-quotes? Single quotes would work just fine, and you don't have to escape as much:

$Convert_string = '/usr/bin/convert -quality 87 -antialias -scale 130x86 -sharpen 1x1 "pic1.jpg" "pic1_converted.jpg"';
system($Convert_string);

Thankyou for your answers, I think English would be a better idea, your right.

The problem is, that unix doesn't execute if i wrapp the source and dst-filename withint "

So, how can I enforce unix to work with this?
Is there a possiblity with Magicqoutes or an similar setting within the php module?

I know that I can edit my Scripts but as I didn't originally develop all these Scripts I don't know anything about how often this System Call is used.

Another interesting fact:
If I disable safe_mode in php, than wrapping the filenames with " is no problem.

Is there any possibility to get round this problems?
