+# Building for PHP
+
+The solution has static and dll projects. Both of them have to be built in
+debug and release mode. The binaries have to be put into the deps tree with
+the following structure:
+
+
+    lib:
+    libiconv_debug.lib
+    libiconv_a_debug.lib
+    libiconv_a.lib
+    libiconv.lib
+
+    include:
+    iconv.h
+
+    bin:
+    libiconv_debug.pdb
+    libiconv_debug.dll
+    libiconv.pdb
+    libiconv.dll
+
+After this the iconv PHP extension can be built static or shared.
