query not resolving right, how to?
i have a query that should return 40 results:
$test = mysql_query(" SELECT fname FROM online_all WHERE verify_status = 'v' LIMIT 40 ");
if (!$test ) {print " - Mysql Error - ";echo fns_et_mysql_error(mysql_error());}
if i echo mysql_num_rows($test);
i get 40
. which means that i get the results
but when i print_r $roww = mysql_fetch_array($test);
i get only one result.
there are no p开发者_Python百科hp errors.
You have to loop through the results with:
while($row = mysql_fetch_array($test)) {
// awesomeness with $row
}
Try using a loop.
while($row = mysql_fetch_array($test)){
}
mysql_fetch_array returns one row at a time. If you want to loop through all of them you do the following:
while ($row = mysql_fetch_array($test))
//Do something
http://php.net/manual/en/function.mysql-fetch-array.php
Check the documentation. mysql_fetch_array only fetches one row of data at a time. To get the data for all 40 rows you need a loop (like a for loop conditioned by mysql_num_rows).
You need to iterate the results from the query.
while($row = mysql_fetch_array($test))
{
// This is how you print fname.
echo $row[0];
}
Please refer to the documentation where there's also many useful tips of how you can use this function.
http://php.net/manual/en/function.mysql-fetch-array.php
You should also know that there exist another useful function for fetching results from mysql queries that fetches results as an associative array.
http://php.net/manual/en/function.mysql-fetch-assoc.php
You have to loop thru the rows:
while($row = mysql_fetch_array($test)){
var_dump($row);
//etectera
}
