The die() function can be used to stop the script and can be used to display a message to the end user. It can be used at the right side of the OR ( || ) operator and at left side can be any expression like the eval() function. Case 1 − Using die() function with no parameter The following is the output. Now we can use $! to print the error number and a message to the user in the die() function. Case 2 − Use of $! in the die() function The following is the ... Read More

To use Server-Sent Events in a web application, you would need to add an element to the document.The src attribute of the element should point to an URL that should provide a persistent HTTP connection that sends a data stream containing the events.The URL would point to a PHP, PERL or any Python script that would take care of sending event data consistently.ExampleHere is an example showing application that would expect server time.                    /* Define event handling logic here */                                                              

This article will discuss how to compare regular expressions in Perl and Python. Regular expressions, or regex, are patterns used to match strings. Both Perl and Python support regex, but they have some differences in syntax and usage. For example, you write a regular expression like this in Perl - $text =~ /pattern/ But you write it like this in Python - re.search('pattern', text) So in the below section of this article will show the similarities and differences between Perl and Python regex with simple examples - ...

When learning different programming languages, you may come across terms like untyped and dynamically typed. While they may sound similar but they have different concepts in how programming languages manage data types. In this article, we will see these concepts in simple terms with simple examples. Untyped Language Untyped programming languages do not have a strict definition of data types. This allows you to use values without providing the data type. The interpreter or execution environment will handle everything anyway it considers a match. Example Let us look at an example that uses an untyped language - # ... Read More
