function data_volcan($pg, $id_ciudad) {
$arr = array();
$anno = 1990;
$i=0;
$ret = array();
while($anno < 2016){
$newString1 = $anno.'-01-01 00:00:00';
$newString2 = $anno.'-12-31 23:59:59';
$string = "SELECT count(evento.id_evento) FROM evento,ciudad_evento WHERE evento.inicio > $1 and evento.inicio > $2 and evento.id_evento = ciudad_evento.id_evento and ciudad_evento.id_ciudad = $3 and evento.tipo = 'volcan'";
array_push($arr,$newString1,$newString2,$id_ciudad);
$result = pg_prepare($pg,"query_data_volcan".$i,$string);
$result = @pg_execute($pg, "query_data_volcan".$i,$arr);
$ans = array();
while ($r = pg_fetch_row($result)) {
$arraytemp = array();
array_push($arraytemp,$r["0"]);
array_push($ans,$arraytemp);
$ret[$i] = $ans[0];
}
$i++;
$anno++;
}
return $ret;
}
此错误在while ($r = pg_fetch_row($result))
为什么呢?我尝试了很多东西,但我找不到错误。

删除&#34; @&#34;,并在pg_execute中看到错误。如果执行没有错误,请使用&#34; pg_last_error&#34;。
