Courses in the relevant section：PHP list, each function traverses the array

<?php $arr=array( '教学部'=>array( array('李某','18','人妖'), array('高某','20','男'), array('张某','21','妖人'), ), '宣传部'=>array( array('李某','18','人妖'), array('高某','20','男'), array('张某','21','妖人'), ), '财务部'=>array( array('李某','18','人妖'), array('高某','20','男'), array('张某','21','妖人'), ), ); while(list($key,$value)=each($arr)){ echo "<h3 style='color:red;text-align:center;'>$key<h3/>"; echo "<table width=100% border=1px double>"; while(list($ke,$va)=each($value)){ echo '<tr>'; while(list($k,$v)=each($va)){ echo '<td>'.$v.'</td>'; } echo '</tr>'; } echo '</table>'; } ?>

編輯過程出錯點: list()與each()應用" = "做連結 style='後需加引號' , 指定項目:結尾注意;項目:結尾;'> echo '<td>'注意.連接.'</td>';
