Issue passing array as argument [to InvokeArg()] in php - var_dump are the same but only one works? -

backstory: creating function handle mysqli , binding data. code in scope of single function. using reflectionclass programmatically invoke mysqli_stmt_bind_param function (as number of arguments vary).

problem: having issue passing array built programmatically ($refarr). when compare var_dump of array (with sample array created directly), 2 arrays identical. invokearg() method runs sample array ($refarr_sample) not $refarr.

here output code shown below:

array(3) { [0]=> string(2) "si" [1]=> string(5) "user1" [2]=> int(0) } - output of refarr

array(3) { [0]=> string(2) "si" [1]=> string(5) "user1" [2]=> int(0) } - output of refarr_sample

$refarr_sample = array("si", "user1", 0);  // var_dump equal in type , length var_dump($refarr); var_dump($refarr_sample);  $ref    = new reflectionclass('mysqli_stmt'); $method = $ref->getmethod("bind_param");  $method->invokeargs($res,$refarr); // doesn't work ????????? //$method->invokeargs($res,$refarr_sample); // works ?????????  $res->execute(); 

i unsure how fix problem (as i've no clue problem is). don't think issue references. once var_dump same thought wouldn't have mattered. did === comparison between 2 arrays came true. @ point lost why isn't working.

i can link complete code (self contained function) if required.

you should note values in passed array must references (as of php 5.3), whereas $refarr built dynamically.

... //assign references foreach ($refarr $key => $value) {    $refarr[$key] =& $refarr[$key]; }  $method->invokeargs($res,$refarr);  ...
