The easiest way to validate an email address in php and html

 The easiest way to validate an email address in php and html <?php if (filter_var('email@myemail.it', FILTER_VALIDATE_EMAIL) === false) { echo ' wrong email'; } ?> via html just use the type "email" for your input and the browser will do the rest if you don't have particular needs. Required will make your input mandatory.   <input type="email" name="email" required> Never use only client side validations/checks.

Fix c:\windows\system32\drivers\etc not resolving hosts to ip address.

Fix c:\windows\system32\drivers\etc not resolving hosts to ip address. Before starting make sure that you have already modified correctly your %SystemRoot%\System32\drivers\etc\hosts file Verify that the path is your registry is pointing to the correct path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath The default value should be %SystemRoot%\System32\drivers\etc Check that you are resolving correctly by using the ping command, it will show the resolved ip address even if unable to ping. Don't use nslookup since it seems to ignore the hosts file by default. Run (theorically useless ... but who knows) this command to flush the nameservers ipconfig /flushdns If you are using a browser remember to clear all your cache.

Get the ID of latest updated rows and automatically update latest modification timestamp

If you want to get the IDs of the latest updated rows it during a query you can do something like that SET @updatedrows := null; /*we will store here the IDs*/ UPDATE mytable SET coltoupdate = 'mycontent' WHERE myID > 5 AND (SELECT @updatedrows := CONCAT_WS(', ', myID, @updatedrows)); SELECT @updatedrows; /*shows the updated IDs*/ If the rows have already been updated via other queries that you are not aware of you, as far as I know, you must have a column (ex. lastmodified) in the database that must be updated each time that you do modifications. To have *automatic* modifications it's better to use the triggers, if supported by your mysql version. (https://dev.mysql.com/doc/refman/5.0/en/create-trigger.html ) /*adding the lastmodified col to the table*/ ALTER TABLE mytable ADD lastmodified DATETIME NOT NULL; /*creating the trigger*/ CREATE TRIGGER updatelastmodified BEFORE UPDATE ON `mytable ` FOR EACH ROW SET NEW.lastmodified = NOW(); After
