mysql_fetch_assoc
Fetch a result row as an associative array
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
mysqli_fetch_assoc
|
PDOStatement::fetch(PDO::FETCH_ASSOC)
|
array mysql_fetch_assoc(resource result);
Returns an associative array that corresponds to the fetched row
and moves the internal data pointer ahead.
mysql_fetch_assoc
is equivalent to calling
mysql_fetch_array
with MYSQL_ASSOC for the optional second parameter. It only
returns an associative array.
result
The result resource that is being
evaluated. This result comes from a call to
mysql_query
.
Returns an associative array of strings that corresponds to the
fetched row, or false
if there are no more
rows.
If two or more columns of the result have the same field names,
the last column will take precedence. To access the other
column(s) of the same name, you either need to access the result
with numeric indices by using
mysql_fetch_row
or add alias names. See the example at the
mysql_fetch_array
description about aliases.
Example 6.21 An expanded
mysql_fetch_assoc
example
<?php $conn = mysql_connect("localhost", "mysql_user", "mysql_password"); if (!$conn) { echo "Unable to connect to DB: " . mysql_error(); exit; } if (!mysql_select_db("mydbname")) { echo "Unable to select mydbname: " . mysql_error(); exit; } $sql = "SELECT id as userid, fullname, userstatus FROM sometable WHERE userstatus = 1"; $result = mysql_query($sql); if (!$result) { echo "Could not successfully run query ($sql) from DB: " . mysql_error(); exit; } if (mysql_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 = mysql_fetch_assoc($result)) { echo $row["userid"]; echo $row["fullname"]; echo $row["userstatus"]; } mysql_free_result($result); ?>
An important thing to note is that using
mysql_fetch_assoc
is not significantly slower than using
mysql_fetch_row
,
while it provides a significant added value.
Field names returned by this function are case-sensitive.
This function sets NULL fields to
the PHP null
value.
