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.

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
What is the use of Mysqli_fetch_assoc?
The mysqli_fetch_assoc() function is used to return an associative array representing the next row in the result set for the result represented by the result parameter, where each key in the array represents the name of one of the result set's columns.
How can I get total number of rows in PHP?
We can get the total number of rows in a table by using the MySQL mysqli_num_rows() function. Syntax: mysqli_num_rows( result ); The result is to specify the result set identifier returned by mysqli_query() function.

Return Values ¶
For successful queries which produce a result set, such as SELECT, SHOW, DESCRIBE or EXPLAIN , mysqli_query() will return a mysqli_result object. For other successful queries, mysqli_query() will return true .
