PHP去除数组中指定的值

//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);
