Strict Standards: Declaration of "This" should be compatible with "That"

[Texan78]

Could someone offer some insight on what this error means exactly. My server did some upgrades over the weekend and went to PHP 5.4 and now I am getting this error on some of my scripts. I did a search but can't trace down exactly what it means in my case.

You were probably getting those errors before too, but your PHP setup had them hidden.

 

ImagePluginAPI defined those four methods according to a certain signature - the set of parameters and such. Your derived implementation in maketropmap needs to use the same signatures.
