我在将 PHP 应用程序从一个数据库迁移到另一个数据库时遇到了一些问题。从 SyBase 到 Interbase。
特别是缺少函数 "ibase_num_rows($result)"。
以下函数帮助了我。
<?php
...
$dbh = ibase_connect ($host, $username, $password);
...
$ar_count_queries = array();
function ibasequery($query) {
$cquery = preg_replace("/SELECT(.*?)FROM(.*?)/","SELECT COUNT(*) FROM \\2",$query);
if ($cquery != $query) {
$crow=get_object_vars( ibase_fetch_object( ibase_query( $GLOBALS["dbh"], $cquery ) ) );
}
@$res = ibase_query($GLOBALS["dbh"],$query);
if (isset($res)) {
if (isset($crow)) {
$GLOBALS["ar_count_queries"][$res] = $radcountselect["COUNT"];
}
return $res;
}
return false;
}
function ibasenumrows($result) {
return $GLOBALS["ar_count_queries"][$res];
}
function ibasefetchrow($result) {
return get_object_vars(ibase_fetch_object($result));
}
$result = ibasequery("SELECT * FROM TABLE");
$numrows = ibasenumrows($result);
echo "行数: $numrows.\n内容: \n";
while ($onerow = ibasefetchrow($res)) {
foreach($onerow as $key => $value) {
echo $key.": ".$value.", ";
}
echo "\n";
}
?>
