Text editor

A text editor is a program which edits files in plain text format, as compared lớn binary format. Using a non-text based word processing program (e.g. Using Microsoft Word to edit PHP scripts) can cause major problems in your code. This is because non-text based word processing programs insert extra formatting into text files, và can corrupt the files when they need lớn be interpreted by the interpreter. An editor lượt thích Notepad does not insert any extra formatting.

Edit Files with a text only editor.

Some examples of file formats which need lớn be edited as plain text:

Rich Text Format documents

Some examples of text editor programs:

Some examples of non-plain text formats that require special software for editing:

Microsoft Word documents Microsoft Excel spreadsheets

Some examples of software which can edit text, but which are NOT regarded as basic text editors và NOT recommended for use on files:

Microsoft Word Microsoft Works Microsoft Excel Adobe Photoshop Adobe Illustrator Adobe Dreamweaver

A widely supported & preferred character encoding system.

For a computer to display letters (or any text characters), it needs khổng lồ enumerate them - create an index of characters it knows how khổng lồ display. These indexes are known as character sets. This is invaluable for users hosting in a non-English language.

The most widely used collections of these character sets are the iso-8859 with iso-8859-1 & iso-8859-15 (which contains the euro sign and some characters used in Dutch, French, Czech và Slovak) being the most common; they are also known as Latin1 & Latin9. These character sets use 8 bits (a single byte) for each character, allowing for 255 different characters (256, counting null). However, when considering that Latin-based languages aren"t the only ones in the world (think Japanese or Hebrew), 255 characters aren"t nearly enough.

There is a wide index of characters known as Unicode. Unicode has so many characters that sometimes more than 16 bits (2 bytes!) are required khổng lồ represent them. Furthermore, the first 127 characters of Unicode are the same as the first 127 of the most widely used character phối - iso-8859-1. For this purpose, UTF, the Unicode Translation Format, was created. UTF uses different numbers of bits for characters, & allows for the entire range of Unicode lớn be used. What you should probably know is:

UTF-8 is an 8-bit-minimum type of UTF. There are also UTF-16 and UTF-32. If your document is in a Latin-based encoding, you probably don"t need to change anything about it for it to be UTF. A single UTF document can be in various languages with no need khổng lồ switch encodings halfway through.

Unix, or UNIX, is a computer operating system developed at AT&T"s Bell Laboratories starting back in 1969. Initially designed with the objective of creating an OS written in a high màn chơi language rather than assembly, a majority of website servers currently run on different "flavors" of this high-performance OS, or on Linux, developed as a Unix-like operating system.

Unix Time

Unix Time, or a timestamp, is a method of tracking time by determining the approximate number of seconds from a particular event. That sự kiện is called an Epoch. Since this time format is only off by a few seconds each century, it is usually considered good enough for most applications.

Unix time is (currently) a ten digit number, và looks lượt thích this lượt thích 1229362315. often uses a Unix timestamp internally to lớn track time. The human readable times and dates you see are converted from Unix Time or from a MySQL DATETIME field.
