How do I get this ID from the URL? I am not the only one for all IDs

I tried: 

  $ id_z_url = $ _GET ['id'] & amp; Amp; $ _GET ['id'] == ''. $ Gildia ['id']. '';   
 But it does not work.   
 
 
 You should try this:  
  $ id_z_url = $ _GET ['Gildia'];   
 With the name of the params, in your case  gildia .  
 When you want to use  $ id_z_url = $ _GET ['id'];  In this way you need to set the name  id  in the URL:

If your purpose is to create one set of the above rows, but remove the 't' in the line So, this is the trick: test => Information (i), 'o', 't', 'b' i. N --- --- --- i | 1 mother 2 o | 3b 5 (4 lines) As a side, unless you specifically want to return the index as a second column, then I unnest () information_schema._pg_expandarray () , which does not appear in the document and is probably...

I have recently switched to autotools to cement, since the limiter cross platform is better for development and what I saw When I build a stable library of my C ++ code, all the files inside .cpp.o is a suffix ar income tax PA8 / libgenericTZR.a genericTZR.cpp.o I have seen other libraries made by other tools and they do not do it, I'm not sure this is the realm And there is a bad thing, but how can I create static libraries without cpp file extension? This is my CMake file add_executable (PA8 ISP_Charges.cpp genericTZR.cpp genericTZR.h) set (LIBSRC genericTZR.c genericTZR.h) add_library (genericTZR shared $ {LIBSRC}) add_library (genericTZR shared $$ TARGET_OBJECTS: myObjects & gt;) install add_library (Generic TZR-static static $ {LIBSRC}) set_target_properties (Generic TZR-Static Properties OUTPUT_NAME $ install (TARGETS PA8 DESTINATION BIN) TARGETS GENICTZR GENERICTZR-STATIC DESTINATION lib) Installed (files "$ {PROJECT_BINARY_DIR} /PA8/genericTZR.h...
