If your WHERE clause is not working in PHP MySQL , there could be a few possible reasons for this. Here are some things to check:
Check for any syntax errors in the query. If the query syntax is incorrect, the WHERE clause may not work as expected. Use echo mysqli_error($ connection ); to display any errors returned by the MySQL database.
Verify that the column name used in the WHERE clause is correct and matches the column name in the MySQL table. Make sure there are no typos or spelling errors.
Check that the value used in the WHERE clause is the correct data type. For example, if the column is an integer, make sure the value is an integer as well. If the column is a string, make sure the value is enclosed in quotes.
Check for any extra whitespace or hidden characters in the value used in the WHERE clause. Use trim () function to remove any whitespace from the value.
Make sure that the value used in the WHERE clause exists in the table. If the value does not exist, the query will not return any rows.
Check that the WHERE clause is using the correct comparison operator ( =, <>, >, <, >=, <=, LIKE, BETWEEN, etc. ) for the data type of the column.
Make sure that the database connection is established and the query is executed properly.
If you have checked all of the above and still have issues with your WHERE clause, please provide more specific details or the code you are using so I can assist you better.
