在每个循环中运行两个数组

Question

am试图同时从import cv2 cap = cv2.VideoCapture(0) while(True): # Capture frame-by-frame ret, frame = cap.read() # Our operations on the frame come here gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) # Display the resulting frame cv2.imshow('frame',gray) if cv2.waitKey(1) & 0xFF == ord('q'): break # When everything done, release the capture cap.release() cv2.destroyAllWindows() 和$num获得结果。那是哪里：

$name

它似乎开始运行，但是将从$ num中获得的第一个值用于num[0] = name[0] 的所有值。

$name

Answer 1

您有foreach（以$ num为$ num的货币）和（以$ name为$ name的货币）尝试为foreach中的Assignememt使用differentnet var name

<?php
    $name = $_POST['name'];
    $num = $_POST['num'];
    foreach ($num as $val1){ 
      foreach ($name as $val2){ 
        $val1* $val2;
      }
    }
