Apps compiled for iOS have their images optimized in some PNG format that is specific to Apple : https://developer.apple.com/library/ios/qa/qa1681/_index.html 为iOS编译的应用程序以特定于Apple的某些PNG格式优化了其图像： https ： //developer.apple.com/library/ios/qa/qa1681/_index.html

Simplest fix would be to run xcrun through exec(), if that is an option for you. 最简单的解决方法是通过exec（）运行xcrun，如果可以的话。

While analyzing the task I came to know that Apple compressed all the PNG Images which are not visible in window and Linux machine but visible on mac machine. 在分析任务时，我知道Apple压缩了所有PNG图像，这些图像在window和Linux计算机上不可见，但在mac计算机上可见。

To use the PNG files, I have to uncompressed these files but unfortunately there is no API or library available to uncompress such files. 要使用PNG文件，我必须解压缩这些文件，但是不幸的是，没有可用的API或库来解压缩此类文件。

While googling I came across the java desktop application (.jar file) which converts compressed iPhone file to PNG image. 在谷歌搜索时，我遇到了Java桌面应用程序（.jar文件），该应用程序将压缩的iPhone文件转换为PNG图像。

So you have to intergrate that .ja r file in php code 因此，您必须在php代码中整合该.ja r文件
