请教一个数组问题
var_export得到$var=mysql_fetch_array(mysql_query($sql))的结果:
array (
  0 => 'a',
)
array (
  0 => 'b',
)
array (
  0 => 'c',
)

如果用in_array函数和某个字段$c匹配,不成功则echo N.

这个表达式要如何表达?







------解决方案--------------------

PHP code

$arr = array ( 0 => array ( 0 => 'question three', 'detail' => 'question three', ), 1 => array ( 0 => 'question four', 'detail' => 'question four', ), 2 => array ( 0 => 'question five', 'detail' => 'question five', ), );
$test = array(0 => 'question three', 'detail' => 'question three',);
if (in_array($test,$arr))
{
    echo 'yes';
}

foreach($var as $key=>$val){<br>	foreach($val as $k=>$v){<br>		if(in_array('c',$v)){<br>			echo "C";<br>		}else{<br>			echo "N";<br>		}<br>	}<br><br>}<br>不知道你的具体是什么样的数组,这样应该可以,你可以试试。 <div class="clear">
                 
              
              
        
            </div>
