php - SELECT WHERE any value in csv in array -


suppose have array:

$city = ["toronto", "chicago", "potato"];

and table looks this:

table name: city_table id    city 1     toronto, orlando 2     buffalo, toledo 3     orlando, tomato 4     potato, chicago, nanaimo

is possible have query gives me result?

id    city 1     toronto, orlando 4     potato, chicago, nanaimo

i tried doesn't work:

$city_string = "'toronto', 'chicago', 'potato'"; select * city_table city in $city_string

to search comma-separated value in mysql use find_in_set. can search 1 item @ time, need call separately each name $city, , combine them and.

select * city_table find_in_set('$city[0]', city_table) or find_in_set('$city[1]', city_table) or find_in_set('$city[2]', city_table)

in actual code should use implode() construct clause dynamically.

note should not have spaces after commas in table, find_in_set not work csv way you've written it.

however, better normalize schema don't have comma-separated value. find_in_set can't optimized index, have perform full table scan.

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.
