PHP去除数组中指定的值

 

<?php  

//一维数组

 

简单的做法  unset($arr[array_search($value,$arr)])

 

 

$arr = array("a","b","c","d");  

function isHave($var){  

  if($var!="b")  

  return true;  

}  

$arr_filter = array_values(array_filter($arr,"isHave"));  

//print_r($arr_filter);  

 

while ( $folder = current ( $folders ) ) {  

    if ($folder == $cur_folder) {  

        $kv = key ( $folders );  

        unset ( $folders [$kv] );  

    }  

    next ( $folders );  

}         

 

//二维数组  

function killarray(&$a,$b,$c){  

    foreach ($a as $key=>$value){  

        if ( isset($value[$b]) && ($value[$b]==$c) ){  

            unset($a[$key]);  

        }  

    }  

}  

$a=array(array('id'=>1,'num'=>10,'type'=>'news'),array('id'=>2,'num'=>100,'type'=>'pic'));  

$b="id";  

$c="1";  

killarray($a,$b,$c);  

print_r($a);
