Building chained function calls dynamically in PHP -


i use php (with kirbycms) , can create code:

$results = $site->filterby('a_key', 'a_value')->filterby('a_key2', 'a_value2');

this chain 2 filterby. works.

however need build function call dynamically. can 2 chained function calls, 3 or more.

how done?

maybe can play code?

chain random number can used create between 1-5 chains.

for( $i = 0; $i < 10; $i ++ ) {     $chains = rand(1, 5); }

examples of desired result

example one, 1 function call

$results = $site->filterby('a_key', 'a_value');

example two, many nested function calls

$results = $site->filterby('a_key', 'a_value')->filterby('a_key2', 'a_value2')->filterby('a_key3', 'a_value3')->filterby('a_key4', 'a_value4')->filterby('a_key5', 'a_value5')->filterby('a_key6', 'a_value6'); 

$chains = rand(1, 5) $results = $site $suffix = '' ( $i = 1; $i <= $chains; $i ++) {     if ($i != 1) {         $suffix = $i     }     $results = $results->filterby('a_key' . $suffix, 'a_value' . $suffix) }

if able pass 'a_key1' , 'a_value1' first call filterby instead of 'a_key' , 'a_value', simplify code removing $suffix , if block , appending $i.

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.
