PHP去除数组中指定的值
<?php//一维数组
简单的做法 unset($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);
