Hey i am a noob when it comes to php because i have just started, and I am trying to execute a ffmpeg co开发者_开发百科de through a function but when i try to execute it, i get an error because '480×360' is replaced with '480×360'and i am not sure whats wrong. Thanks you in advance.

Your x character, rather than being a lowercase letter x, is the unicode codepoint D7 which is the multiplication sign. This has the UTF-8 representation C397. You are seeing the bytes C3 and 97 which are appearing as your accented A and dash due to you viewing things in the Windows CP1252 encoding.

As regards a specific resolution, you could try replacing the multiplication sign with a lower case x. You've not mentioned your specific function, so this may not be the appropriate resolution.

You are passing the weird version of the x and not an actual x. You need to change it to simply be an x.
