How to dump a user defined or system compiled function in PHP?


How to dump a user defined or system compiled function in PHP?

I think the issue was by ths following , Such a function would be powerful.
Some tools outside of PHP will help: A debugger, like gdb; a refactoring tool, like resharper/MonoDev and some tracing tools, like strace/dtrace. You would also use some tools, which expose internals, like Derick's VLD or PVT, which can dump the opcodes to a readable format, from there, it's not totally impossible to (re)create the code from it.
code :


Share : facebook icon twitter icon

it fixes the issue I am using MS-sql server 2008 , This query will show you all the permissions a user has:
code :
select * from fn_my_permissions(NULL, 'DATABASE')

should help you out It's possible, but you need to reference the function by the user's schema
code :
select dbo.TIME_TO_SEC('01:00:00') from TimeTable

I wish did fix the issue. , The parameter passed to system() is wrong:
code :
system(outputdirectorycommand.c_str && exportcommand.c_str());
string cmdToExecute = outputdirectorycommand + " && " + exportcommand;
system(cmdToExecute.c_str());

Does that help Db2 for i does not have a CREATE FUNCTION (aggregate) statement even in the current 7.4 release. https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_74/db2/rbafzcreatef.htm
You should know that Db2 for i, Db2 for z and Db2 (for LUW) are essentially separate products, and although there is certain amount of common syntax and features, you do need to look at manual pages (and web articles etc) for you particular platform (and ideally version level)

I hope this helps you . You can try using a macro for each function and then just define it depending on your macro MYMATH. Also if you prefer avoiding this kind of macros you can use a generic lambda as a wrapper.
MyMath.hpp
code :
#ifdef MYMATH
#define imp_sin(x) f_sin(x)
#else
#include <cmath>
#define imp_sin(x) std::sin(x)
#endif
#define glambda(x) [](auto y){ return x(y); }
#ifdef MYMATH
auto imp_sin = glambda(f_sin);
#else
#include <cmath>
auto imp_sin = glambda(std::sin);
#endif
#undef glambda //Or not if you want to keep this helper
#include "MyMath.hpp"
int main(int, char**) {
  imp_sin(3.4f);
  return 0;
}
