1)我想将case 1值保存到数组中。返回此数组并将其传递给函数。代码变为案例2,但没有结果出来,问题在哪里?
2)在函数display_urls中,我想回显$ url和$ category。我应该在IF条件下做什么或添加另一行代码?
function display_urls($url_array)
{
echo "";
if (is_array($url_array) && count($url_array)>0)
{
foreach ($url_array as $url)
{
echo "".$url."";
echo "".$category."";
}
}
echo "";
}
案例1:工作正常
$result = oci_parse($conn, "select * from bookmark where username ='$username'");
if (!$result){ $err = oci_error(); exit; }
$r = oci_execute($result);
$i=0;
echo "";
while( $row = oci_fetch_array($result) ){
$i++;
echo "";
echo "".$row['USERNAME']."";
echo "".$row['BM_URL']."";
echo "".$row['CATEGORY']."";
echo "";
}
echo "";
案例2:
$url_array = array();
while( $row2 = oci_fetch_array($result, OCI_BOTH)){
$i++;
$url_array[$count] = $row[0];
}
return $url_array;
答案 0 :(得分:0)
我想你可能想要这样的东西:
function display_urls($url_array)
{
echo "";
if (is_array($url_array) && count($url_array)>0)
{
foreach ($url_array as $url)
{
echo "".$url['BM_URL']."";
echo "".$url['CATEGORY']."";
}
}
echo "";
}
$result = oci_parse($conn, "select * from bookmark where username ='$username'");
if (!$result){ $err = oci_error(); exit; }
$r = oci_execute($result);
$url_array = array();
while( $row = oci_fetch_array($result, OCI_ASSOC)){
$url_array[] = $row;
}
display_urls($url_array);
这将存储$ url_array中URL的所有信息,并按列名进行查找。
