Perl Language: PERL Stands for Practical Extraction and Report Language. Perl is a High-level General Purpose Programming language used especially for developing Web Applications. It’s the Dynamic Programming languages. It’s not a compiled language Perl used for Administration, Web Development, Networking Programming, GUI Development, etc. It’s the Open source Software, Artistic license, and General public license.

Why is Perl Programming needed?

It’s used in Command line scripting to manipulate text. The Programmer used Perl to create a software application. Perl process, file, and text manipulation facilities make it particularly used for a task involving quick prototyping, System utilities, Software tools, System management task, database access, graphical programming, networking, and Learn Programming Language.

Learn Perl programming is a scripting language. It was an open source so users can easily download and modify thousands of Perl scripts for your use.

Features of Perl Programming

• Perl works with HTML, XML and other marks- up languages.
• Compare to another language they give best and efficient features.
• Its support the Object orientated Programing’s in Networking courses.
• In reality, Perl interchange with embedded into other systems in Networking Trends.
• Perl Database Integration Interface DBI Supports third-party access.

Data types

Perl contains three basic Data types like Scalar, Arrays, and Hashes.

Scalar: Scalar denotes as a HTML Course Symbol of “$.” It’s Contains either String, a number of references. A Reference is to identify the address of the variables.

Arrays: Arrays denote as a Symbol of “@.” List of scalars that access with a numeric index.

Hashes: In fact, hashes denote as a Symbol of “%.” Hashes are unordered sets of key/value pairs that you access using the keys as subscripts.

Perl Variables

Variables stands for memory location to store a values.

Creating Variables: In Perl variable avoid reserving memory space. The “=” Symbol is used to assign a value to variables automatically.

Scalar Variables: It’s a single unit of data. It may contain integer number, floating point, a character, a string, a paragraph, or an entire web page.

Array Variables: An Array is a variable that stores an ordered list of scalar values in python framework. It is referring to a single element of an array.

Hash Variables: A Hash is a set of Key/Value Paris. It is referring to a single element of a hash you will use the hash variable name followed by the key associated with the value in curly brackets.
