PHP traverses the array code in three ways

: This article mainly introduces PHP code for traversing arrays. you can refer to these three methods for PHP tutorials. $ People = array ("Peter", "Joe", "Glenn", "Cleveland ");
$ People1 = array ("Peter", "Joe", "asd" => "Glenn", "Cleveland ");
// 7. list (variable 1, variable 2, variable 3); used together with each to traverse the array.
// The list function assigns values to a group of variables with elements in the array.
// This function is only used for the number index array, and it is assumed that the number index starts from 0.
List ($ a1, $ a2, $ a3) = $ people1; // assign the array people1 to list
Echo $ a1. $ a2. $ a3; // output the values in the list.
Echo"

";
// 6. each (array1); generates an array consisting of the key and key values of the elements pointed to by the current internal pointer of the array,
// Move the internal pointer forward.
Print_r (each ($ people ));
Print_r (each ($ people ));
Reset ($ people); // reset the pointer
// Give the key and value in people1 to list
While (list ($ key, $ val) = each ($ people1 ))
{
Echo "$ key => $ val
";
}
For ($ I = 0; $ I
 
  
Echo $ people [$ I]."
  
";
  
}
  
Foreach ($ people as $ v ){
  
Echo $ v ."
  
";
  
}
