php can output two arrays at the same time, as long as the key names of the two arrays are consistent. Implementation steps: 1. Use the foreach statement to traverse the key names and key values of an array, with the syntax "foreach ($array1 as $key => $value){//loop body statement block;}"; 2. In the loop body, Just output the element value "$value" directly and output the element value "$array2[$key]" of another array according to the key name "$key".

In php, you can use foreach (or for) statement to output two arrays at the same time, as long as the key names of the two arrays are consistent.

  • The for statement can only traverse the index array

  • The foreach statement can traverse the index array and the associative array

    foreach It is a statement specially designed for traversing arrays. It is a commonly used method when traversing arrays. It provides great convenience in traversing arrays. After PHP5, you can also traverse objects (foreach can only be applied to arrays and objects).

    The foreach statement traverses the array regardless of the array subscript, and can be used for discontinuous index arrays and associative arrays with strings as subscripts.

Implementation steps:

Step 1: Use the foreach statement to traverse the key names and key values of an array

foreach ($array1 as $key => $value){ //循环体语句块; }

  • Traverse the given $array1 array, and in each loop, the value of the current array will be assigned to $value, and the key name will be assigned to $key.

Step 2: In the loop body, output the element value $value of $array1 and output the element value of $array2 according to the key name $key

echo $value."
"; //输出$array1的元素值 echo $array2[$key]."
"; //输出$array2的元素值
Copy after login

Implementation example

 $value){ echo $value." ".$array2[$key]."
"; } ?>
Copy after login
