5 min readTo match lines in a numbered list with a regex, you can use the following pattern:^\d+.\s.*$This regex pattern matches lines that start with one or more digits followed by a period, a whitespace character, and any other characters.You can use this pattern to match and extract lines in a numbered list in many programming languages that support regex, such as Python, Java, and JavaScript.Remember to adjust the regex pattern if your numbered list uses a different format or numbering system.

4 min readTo exclude a word with regex, you can use negative lookahead assertion. This means that you specify the word you want to exclude by placing it within parentheses preceded by a caret (^). For example, to exclude the word "example" from a regex pattern, you would write it as ^(?!example). This will ensure that the regex pattern does not match any string that contains the word "example".

4 min readTo track emails sent over SMTP via code, you can use a combination of programming languages such as Python, Java, or C# along with SMTP libraries like smtplib or JavaMail. By including tracking logic in your email sending code, you can capture various events like successful sends, bounces, opens, and clicks through unique links. Make sure to handle SMTP server responses and potential errors to ensure accurate tracking and analytics.

3 min readTo check a phone number using regex, you can define a regular expression pattern that matches the format of a typical phone number. This pattern can include the specific number of digits, any optional characters like hyphens or parentheses, and any specific rules for the format of the phone number. For example, a regex pattern for a standard US phone number might look like this: ^(?\d{3})?[-.\s]?\d{3}[-.\s].

3 min readTo make a regex match all or nothing, you can use the anchors ^ and $. The ^ anchor matches the beginning of the input string, while the $ anchor matches the end of the input string. By combining these anchors with your regex pattern, you can ensure that the entire input string is matched or nothing is matched at all. This allows you to specify the exact boundaries for your regex match and avoid partial matches.

5 min readTo send mail with SMTP authentication in PHP, you can use the PHPMailer library which provides an easy way to send emails using SMTP. First, you need to download and include the PHPMailer library in your project. Next, you need to set up the SMTP configuration including the SMTP server address, port, username, password, and authentication method. Then, create a new instance of PHPMailer and set the From, To, Subject, and Body of the email.

4 min readTo make a query parameter optional in regex, you can use the "?" quantifier after the parameter in the regular expression pattern. This quantifier specifies that the preceding element can occur 0 or 1 times. This allows you to search for patterns with or without the specified parameter in the query. By making the parameter optional, you can search for a wider range of matches in the text.

8 min readTo send SMTP mail from localhost, you need to have a local SMTP server installed on your computer. This can be done by setting up a mail server such as Postfix, Sendmail, or Exim. Once the SMTP server is installed and configured, you can use a programming language such as PHP or Python to send emails through the SMTP server. In your code, you will specify the SMTP server details, such as the host, port, username, and password.

3 min readTo match an expression using regex, you first need to define the pattern you are looking for in the form of a regular expression (regex). This pattern can include specific characters, wildcards, ranges, and other regex features.Once you have the regex pattern defined, you can then use a regex function or method in your programming language or text editor to search for and match the pattern in the text or string you are working with.

7 min readTo solve the send mail ORA-29279 SMTP issue, you can try the following troubleshooting steps:Check your SMTP server settings to ensure they are correct.Verify that your firewall or antivirus software is not blocking the SMTP connection.Make sure that the recipient email address is entered correctly.Check the logs for any specific error messages that could provide more information on the issue.Test the SMTP connection using a different email client or tool to see if the problem persists.

3 min readTo remove a character from a regular expression (regex), you can use the built-in functions or methods provided by the programming language or tool you are using. One common approach is to use the "replace" function to replace the character with an empty string. For example, if you want to remove the character 'a' from a regex pattern, you can use the "replace" function to replace all occurrences of 'a' with an empty string.

4 min readParsing key-value pairs with regex involves using regular expressions to capture the key and value parts of the input string. This can be done by constructing a regex pattern that matches the desired format of the key-value pairs, and then using capturing groups to extract the key and value components. The key and value can then be retrieved from the captured groups for further processing.For example, if the key-value pairs are in the format "key1=value1, key2=value2, ...
