mysql_fetch_row

(PHP 4, PHP 5)

mysql_fetch_row숫자 색인 배열로 결과를 반환

설명

array mysql_fetch_row ( resource $result )

인출된 행과 일치하는 숫자 색인 배열을 반환하고, 앞으로 내부 데이터 포인터를 이동한다.

인수

result

mysql_query() 호출을 통한 결과 resource.

반환값

인출된 행에 대응하는 문자열의 숫자 색인 배열을 반환하거나 더 이상의 행이 없으면 FALSE를 반환한다.

mysql_fetch_row()는 지정된 result 식별자와 연관된 결과로부터 하나의 데이터 행을 인출하며, 배열로 반환한다. 각 결과 컬럼은 0으로 시작하는 배열 오프셋(offset)에 저장이 된다.

예제

Example #1 mysql_fetch_row()를 이용한 하나의 행 인출 예제

<?php
$result 
mysql_query("SELECT id,email FROM people WHERE id = '42'");
if (!
$result) {
    echo 
'Could not run query: ' mysql_error();
    exit;
}
$row mysql_fetch_row($result);

echo 
$row[0]; // 42
echo $row[1]; // the email value
?>

주의

Note: 이 함수는 NULL 필드를 PHP NULL 값으로 설정합니다.

참고

Creates table from all db info:

<?php
$qry
= "SELECT * FROM exp_member_data";
$res = mysql_query($mem_qry);

function
mysql_fetch_all($res) {
   while(
$row=mysql_fetch_array($res)) {
      
$return[] = $row;
   }
   return
$return;
}

function
create_table($dataArr) {
    echo
"<tr>";
    for(
$j = 0; $j < count($dataArr); $j++) {
        echo
"<td>".$dataArr[$j]."</td>";
    }
    echo
"</tr>";
}

$all = mysql_fetch_all($res);

echo
"<table class='data_table'>";

for(
$i = 0; $i < count($all); $i++) {
   
create_table($all[$i]);
}

echo
"</table>";

?>

sry :) note now fixed:

<?php
$esi
=mysql_list_tables($db);$ris=mysql_fetch_row($esi);
//example: $db has >= 1 tabs
echo var_dump($ris);
//echoes only array(1). solution:
while($ris=mysql_fetch_row($esi)) echo $ris[0];
/*debug:
$ris=array("1st_tab"); ... $ris=array("n_tab");$ris=false;*/
while ($ris[]=mysql_fetch_row($esi));
//debug:$ris=array(array("1st_tab"), ... array("n_tab"));
echo $ris[n][0];//echo:"n_tab"
echo $ris[0][n];//echo:array | null
?>

hope it helps

The following are the basic codes to get a specific row from the mysql db into a $row variable:

 
$query = "SELECT * FROM table";
$result = mysql_query($query);
$row = mysql_fetch_row($result);

And $row[0], $row[1] ... $row[n] are used to access those field values.

Does anyone know how I can add a new field to $row, so that the field count increases from n to n+1?

I have tried treating $row like an array, and tried array_push function, but didn't work.

Thanks.

The following function to read all data out of a mysql-resultset, is may be faster than Rafaels solution:

<?
function mysql_fetch_all($result) {
   while($row=mysql_fetch_array($result)) {
       $return[] = $row;
   }
   return $return;
}
?>

It is probably worth pointing out that the array elements will actually be of type string, OR NULL if the field is null in the database.

Thus, either use a double equal comparison to look for empty or null

Or, use a triple equal comparison to be able to distinguish the two cases

e.g.

if ($field === '') echo "Empty, not NULL\n";

if ($field === NULL) echo "NULL\n";

if ($field == '') echo "Empty or NULL\n";

to print an array, simply use print_r(array name)

like this:
    $myrow = mysql_fetch_row($result);
echo "<pre>";
print_r($myrow);
echo "</pre>";

this will output the array in a readable form, with the index, too. Don't forget the 'pre' tags or the output will be on a single line.

Maybe worth pointing out that all the fields returned by this (and other?) calls are returned with type string. This had me puzzled for quite some time.
