php - JSON module is probably installed but json_encode() doesn't exist -


i've installed lamp on ubuntu 14.04 , php5-json module. seems installed because it's situated on list of modules on phpinfo() page. phpinfo()

but function_exists("json_encode") returns false

update:
solved problem editing file path marked below: enter image description here

two ideas coming mind :

  • restart server after module installation ?

  • check php.ini , line looks :

    extension=json.so

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
