1、foreach语句

好多语言都有foreach语句，PHP也不例外

    1 ,    'b' => 2,    'c' => 3,    'd' => 4,  );  foreach ($arrayName as $key => $value) {
     //第一种    echo "$key->$value
";  }  echo "----
";  foreach ($arrayName as $value) {
     //第二种    echo $value."\t";  } ?>

foreach语句不支持使用@f符号屏蔽错误信息

foreach打印表格

    "类别", '2' => "数量", "3" => "价格");   $array1 = array('1' => "电脑", '2' => "电视", "3" => "手机");   $array2 = array('1' => "999", '2' => "888", "3" => "777");   $array3 = array('1' => "6999", '2' => "2999", "3" => "3999"); ?>          
                        
   
$value";            }          ?>       
 $value) {
               echo "
";          }        ?>     
           
     
                    
                 
                    
$array1[$key]
                    
$array2[$key]
                    
$array3[$key]
                 
    
   
    

运行结果：
