pg_connection_busy 获知连接是否为忙


bool pg_connection_busy ( resource $connection )

pg_connection_busy() 在此连接状态为忙的时候返回 TRUE。如果连接状态为忙,说明前一个查询仍然在执行。如果调用 pg_get_result() 函数的话,则会被锁死。

Example #1 pg_connection_busy() 例子

pg_connect("dbname=publisher") or die("Could not connect");
$bs pg_connection_busy($dbconn);
    if (
$bs) {
'connection is busy';
    else {
'connection is not busy';

pg_connection_busy() returning true does not necessarily mean that there are results waiting for pg_get_result(); it also stays true for some time after a query that causes any sort of postgres error. (See
