Output php multidimensional array to html list

问题:

I have the following array set in a php script and i am trying to get it to output as per the code below. I have tried looping but i am at a loss as to how i get it to show the sub arrays. I am hoping someone can help me.

PHP Array

$fruits = array(); $fruits[] = array('type' => 'Banana', 'code' => 'ban00'); $fruits[] = array('type' => 'Grape', 'code' => 'grp01'); $fruits[] = array('type' => 'Apple', 'code' => 'apl00',                array('subtype' => 'Green', 'code' => 'apl00gr'),                array('subtype' => 'Red', 'code' => 'apl00r')             ); $fruits[] = array('type' => 'Lemon', 'code' => 'lem00'); 

Desired Output

<ul>     <li><input type="checkbox" name="fruit" value="Banana"> Banana</li>     <li><input type="checkbox" name="fruit" value="Grape"> Grape</li>     <li>Apple         <ul>             <li><input type="checkbox" name="fruit" value="Green"> Green</li>             <li><input type="checkbox" name="fruit" value="Red"> Red</li>         </ul>     </li>     <li><input type="checkbox" name="fruit" value="Lemon"> Lemon</li> </ul>

You can use recursive function. Note that this is a example and not a direct solution, as we are here to learn and not to get the job done - change this as needed.

function renderList(array $data) {    $html = '<ul>';    foreach ($data as $item) {       $html .= '<li>';       foreach ($item as $key => $value) {          if (is_array($value)) {              $html .= renderList($value);          } else {              $html .= $value;          }       }       $html .= '</li>';    }    $html .= '</ul>';    return $html; }  $data = array(); $data[] = array('A'); $data[] = array('B', array(array('C'))); $data[] = array('D');  echo renderList($data); 

The output of this will be:

• A
• B
  • C
• D

Or in html form:

<ul>     <li>A</li>     <li>B         <ul>             <li>C</li>         </ul>     </li>     <li>D</li> </ul>

You need to do something like this.I have not tried to code you for you, just tried to give you an idea.I hope you can proceed.

echo '<ul>';     foreach( $fruits as $fruit){     echo  '<li>' . $fruit . '</li>';         if( is_array($fruit) ){              echo  '<ul>';              foreach( $fruit as $fr ){                  echo '<li>' . $fr . '</li>';              }            echo '</ul>';     }         }echo '</ul>';     }

<?php  $fruits = array(); $fruits[] = array(     'type' => 'Banana',     'code' => 'ban00' ); $fruits[] = array(     'type' => 'Grape',     'code' => 'grp01' ); $fruits[] = array(     'type' => 'Apple',     'code' => 'apl00',     array(         'subtype' => 'Green',         'code' => 'apl00gr'),     array(         'subtype' => 'Red',         'code' => 'apl00r'     ) ); $fruits[] = array(     'type' => 'Lemon',     'code' => 'lem00' );  iterate($fruits, 'type');  function iterate($fruits, $index) {     foreach ($fruits as $fruit) {         echo "<ul>";         display($fruit, $index);         echo "</ul>";     } }  function display($data, $index) {     echo '<li><input type="checkbox" name="fruit" value="' . $data[$index] . '">' . $data[$index];     if (!empty($data[0]) && is_array($data[0])) {         $newSubArray = $data;         unset($newSubArray['type']);         unset($newSubArray['code']);         iterate($newSubArray, 'subtype');     }     echo "</li>"; }
