每当我在下面的函数中调用WP_Query()时,Wordpress就会泄漏8兆的内存。而且,由于我多次调用此函数,所以事情很快就变得很毛茸茸了……:(我尝试取消生成的$ queryObject以及定期调用wp_cache_flush(),但似乎都没有任何效果。
function get_post_ids_in_taxonomies($taxonomies, &$terms=array()) {
$post_ids = array();
$query = gen_query_get_posts_in_taxonomies($taxonomies, $terms);
// var_dump($query);
//Perform the query
$queryObject = new WP_Query($query); //*****THE 8 MEGABYTES IS LEAKED HERE*****
//For all posts found...
if($queryObject->have_posts()) {
while($queryObject->have_posts()) {
$queryObject->the_post();
//Get the $post_id by capturing the output of the_ID()
ob_start();
the_ID();
$post_id = (int) ob_get_contents();
ob_end_clean();
// echo $post_id."\n";
$post_ids[] = $post_id;
}
}
unset($queryObject);
return $post_ids;
}
gen_query_get_posts_in_taxonomies()是:
function gen_query_get_posts_in_taxonomies($taxonomies, &$terms=array()) {
//General query params
$query = array(
'posts_per_page' => -1, //Get all posts (no paging)
'tax_query' => array('relation' => 'OR'),
);
//Add the specific taxonomies and terms onto $query['tax_query']
foreach($taxonomies as $tax) {
//Get terms in the taxonomies if we haven't yet
if(!array_key_exists($tax, $terms)) {
$terms[$tax] = array();
$terms_tmp = get_terms($tax);
foreach($terms_tmp as $tt)
$terms[$tax][] = $tt->term_taxonomy_id;
}
$query['tax_query'][] = array(
'taxonomy' => $tax,
'terms' => $terms[$tax],
'field' => 'term_taxonomy_id',
);
}
return $query;
}

如果您的情况下(泄漏8mb时)获取多少个帖子?
