创建数组

  1. <?php
  2. $arr1=array(
  3. '欧阳',
  4. '张三',
  5. '李四'
  6. );
  7. ?>

关联数组与索引数组

  1. 用数字作为键名的数组一般叫做索引数组。用字符串表示键的数组就是下面要介绍的关联数组。

索引数组

  1. <?php
  2. //索引数组
  3. $arr1 = array['0'=>'小张', '1'=>'小刘',2=>'小于'];
  4. //关联数组
  5. $arr1 = array['IT1'=>'小张', 'IT2'=>'小刘','IT3'=>'小于'];
  6. ?>

访问数组的数据

  1. <?php
  2. $arr1=array(
  3. '欧阳',
  4. '张三',
  5. '李四'
  6. );
  7. // var_dump($arr1);
  8. print_r($arr1);

二维三维数组及循环

  1. <?php
  2. $arr2=[
  3. '200001'=>'黄浦',
  4. '200002'=>'徐汇',
  5. '200003'=>'嘉定'
  6. ];
  7. // print_r($arr2);
  8. // print_r($arr2[200001]);
  9. // echo $arr2[ 200002 ];
  10. // print_r($arr1[1]);
  11. $arr3 = [
  12. 'name'=>'Xiao hu',
  13. 'age'=>'28',
  14. 'job'=>[
  15. 'coding',
  16. 'cleaning',
  17. 'service'
  18. ]
  19. ];
  20. // print_r( $arr3['name']);
  21. $arr4 = [
  22. [
  23. 'name'=>'Ouyang',
  24. 'age'=>'28',
  25. 'job'=>'it'
  26. ],
  27. $arr3,
  28. [
  29. 'name'=>'Hu lao shi',
  30. 'age'=>'38',
  31. 'job'=>'it2'
  32. ]
  33. ];
  34. // print_r($arr4[1]['name']);
  35. //output Xiao hu
  36. foreach ( $arr4 as $v ){
  37. print_r( $v['name'] );
  38. foreach( $v['job'] as $vzzv){
  39. echo '--'.$vv.'--';
  40. }
  41. echo '<hr />';
  42. }
