If $row<\/code> and $ar<\/code> have an equal element count, I don’t see the reason for two loops. Your original code will do four iterations, and I’m not sure that’s what you want. (Judging by my uncertainty and the number of negative votes, you should probably update your question asap.)<\/p>\n

Code: (Demo<\/a>)<\/p>\n

$arr=['11','12'];\n$ar=['1','2','3','4','5'];\n\n\/\/ shuffle and index $data subarrays\nforeach($arr as $v){\n    shuffle($ar); \/\/ just shuffle before the next loop\n    $data[]=['stdid'=>$v,\"tid\"=>$ar];\n}\nvar_export($data);\n\n$data=[];  \/\/ clear the array\necho \"\\n\\n---\\n\\n\";\n\n\/\/ or shuffle and use stdid as subarray keys for $data\nforeach($arr as $v){\n    shuffle($ar); \/\/ just shuffle before the next loop\n    $data[$v]=[\"tid\"=>$ar];\n}\nvar_export($data);\n<\/code><\/pre>\n
