Understanding Single-Row Retrieval in MySQL Interactions
In your provided code, you're utilizing the mysql_query() function to retrieve a result set from a MySQL database and subsequently attempt to fetch rows using mysql_fetch_array(). However, you're encountering an issue where only the first row is accessible.
The mysql_fetch_array() function retrieves a row from the result set and represents it as an indexed array. In your case, each row corresponds to a set of matching artist names that begin with "a," "b," or "c."
When you execute mysql_fetch_array() the first time, it places the first row of the result set into the $array_result variable, making $array_result[0] available. However, the subsequent calls to mysql_fetch_array() without specifying a parameter will always return the first row, overwriting previous results.
To fetch multiple rows from the result set, you need to repeat the mysql_fetch_array() function within a loop. For instance, you could use a while or foreach loop to iterate through the result set, calling mysql_fetch_array() within each iteration and storing the resulting array in a variable. This will allow you to access each row individually and echo its contents as desired.
Here's an example using a while loop:
$array = mysql_query("SELECT artist FROM directory WHERE artist LIKE 'a%' OR artist LIKE 'b%' OR artist LIKE 'c%'"); while($row = mysql_fetch_array($array)) { var_dump($row); // Outputs contents of each row }
This loop will iterate through the result set and output the contents of each row, allowing you to access and echo all the available data from the query.
The above is the detailed content of Why Does My MySQL `mysql_fetch_array()` Only Return the First Row?. For more information, please follow other related articles on the PHP Chinese website!

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
