valentina_fetch_assoc()

Declaration

array valentina_fetch_assoc ( resource result )

Parameters

Name Description
resultThe result resource that is being evaluated. This result comes from a call to valentina_query().

Description

Returns an associative array that corresponds to the fetched row and moves the internal data pointer ahead. valentina_fetch_assoc() is equivalent to calling valentina_fetch_array() with VALENTINA_ASSOC for the optional second parameter. It only returns an associative array.

Return Values

Returns an associative array that corresponds to the fetched row, or FALSE if there are no more rows.

Examples

Example 1.

<?php
 
$conn = valentina_connect("localhost", "val_user", "val_password");
 
if (!$conn) {
   echo "Unable to connect to DB: " . valentina_error();
   exit;
}
 
if (!valentina_select_db("mydbname")) {
   echo "Unable to select mydbname: " . valentina_error();
   exit;
}
 
$sql = "SELECT userid, fullname, userstatus 
       FROM  sometable
       WHERE  userstatus = 1";
 
$result = valentina_query($sql);
 
if (!$result) {
   echo "Could not successfully run query ($sql) from DB: " . valentina_error();
   exit;
}
 
if (valentina_num_rows($result) == 0) {
   echo "No rows found, nothing to print so am exiting";
   exit;
}
 
// While a row of data exists, put that row in $row as an associative array
// Note: If you're expecting just one row, no need to use a loop
// Note: If you put extract($row); inside the following loop, you'll
//      then create $userid, $fullname, and $userstatus
while ($row = valentina_fetch_assoc($result)) {
   echo $row["userid"];
   echo $row["fullname"];
   echo $row["userstatus"];
}
 
valentina_free_result($result);
 
?> 

Notes

Performance: An important thing to note is that using valentina_fetch_assoc() is not significantly slower than using valentina_fetch_row(), while it provides a significant added value.

Note: Field names returned by this function are case-sensitive.

Note: This function sets NULL fields to PHP NULL value.
