I am so glad you dropped the ls. You are using bash. Learn it's great features. I am not quite sure what you are trying to accomplish though this is what I gather.

1. Find all files ending with ".sql" in current directory
2. Place them all in an array.
3. Count how many elements are in the array.

Code:
#!/bin/bash
sqlfiles=( *.sql )
echo "${#sqlfiles[@]}"

MYSQL_FETCH_ASSOC(3)							 1						      MYSQL_FETCH_ASSOC(3)

mysql_fetch_assoc - Fetch a result row as an associative array

SYNOPSIS
Warning This extension is deprecated as of PHP 5.5.0, and will be removed in the future. 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: omysqli_fetch_assoc(3) o PDOStatement::fetch array mysql_fetch_assoc (resource $result) DESCRIPTION
Returns an associative array that corresponds to the fetched row and moves the internal data pointer ahead. mysql_fetch_assoc(3) is equiv- alent to calling mysql_fetch_array(3) with MYSQL_ASSOC for the optional second parameter. It only returns an associative array. o $ result -The result resource that is being evaluated. This result comes from a call to mysql_query(3). 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(3) or add alias names. See the example at the mysql_fetch_array(3) description about aliases. Example #1 An expanded mysql_fetch_assoc(3) 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); ?> Note Performance An important thing to note is that using mysql_fetch_assoc(3) is not significantly slower than using mysql_fetch_row(3), while it provides a significant added value. Note Field names returned by this function are case-sensitive. Note This function sets NULL fields to the PHP NULL value. mysql_fetch_row(3), mysql_fetch_array(3), mysql_data_seek(3), mysql_query(3), mysql_error(3). PHP Documentation Group MYSQL_FETCH_ASSOC(3)
