An array is a special variable, which can store multiple values in one single variable. • In PHP, there are three kind of arrays: – Numeric array - An array with a. PHP Functions Essential Reference is a detailed and practical function function groups plus additional commonly used PHP functions, and details The PHP Hypertext Preprocessor (PHP) is a programming language that allows web .. PHP Function Parameters. .. PHP Functions with Parameters.
It is backed by the Intl extension, available since PHP 5. If you decide to go for one of the libraries that provide no extractors, you may want to use the gettext formats, so you can use the original gettext toolchain including Poedit as described in the rest of the chapter. Gettext Installation You might need to install Gettext and the related PHP library by using your package manager, like apt-get or yum. Here we will also be using Poedit to create translation files.
Structure Types of files There are three files you usually deal with while working with gettext. Domains There are some cases, in big projects, where you might need to separate translations when the same words convey different meaning given a context. In those cases, you split them into different domains.
In Symfony projects, for example, domains are used to separate the translation for validation messages. Locale code A locale is simply a code that identifies one version of a language. It is defined following the ISO and ISO alpha-2 specs: two lower-case letters for the language, optionally followed by an underline and two upper-case letters identifying the country or regional code.
For rare languages , three letters are used. For some speakers, the country part may seem redundant. Directory structure To use Gettext, we will need to adhere to a specific structure of folders. First, you will need to select an arbitrary root for your l10n files in your source repository.
Plural forms As we said in the introduction, different languages might sport different plural rules.
However, gettext saves us from this trouble once again. When creating a new.
Version: 1. Use it to make something cool, have fun, and share what you've learned with others.
The only difference is that the former has no return value and can take several parameters, while the latter has a return value of 1 and can only take one argument. An important note: Like all other PHP commands, functions echo and print are not case sensitive. Instead, you create them once and use the shortcuts when you need them.
Much of this PHP cheat sheet is devoted to that. After that, everything between the curly braces is what the function does when called. Variables and Constants Similarly to most other programming languages, PHP lets you work with variables and constants. These are pieces of code that store different kinds of information.
Defining Variables To do anything with variables, you first need to define them.

They must have at least one digit and no decimal point. Can be in decimal, hexadecimal or octal. Floats — This is the name for numbers with a decimal point or in exponential form.
Strings — This simply means text, we will talk about it in detail further below. Arrays — Arrays are variables that store several values. We will talk about them in detail further below. The documentation in this section is only meant to be an overview of the available functions in the PDFlib library and should not be considered an exhaustive reference. It provides a very good overview of what PDFlib is capable of doing and contains the most up-to-date documentation of all functions.
For a jump start we urge you to take a look at the programming samples which are contained in all PDFlib distribution packages. These samples demonstrate basic text, vector, and graphics output as well as higher-level functions, such as the PDF import facility PDI.
Unless configured otherwise, all lengths and coordinates are measured in PostScript points. There are generally 72 PostScript points to an inch, but this depends on the output resolution. The main difference is the following: Please see the examples below for more information. Requirements PDFlib Lite is available as open source.
However, the PDFlib Lite license allows free use only under certain conditions. The full version of PDFlib is available for download at http: PDFlib 4. Resource Types This extension has no resource types defined.I had to make a opensource solution for creating simpel report analyses that's based on things like: We have already talked about the necessary tools to do so.
I guess the compression is confusing IE. After one hole day understanding how pdflib works i got the conclusion that its enough hard to draw just with words to furthermore for drawing a line maybe you will need something like four lines of code, so i did my own functions to do the life easier and the code more understable to modify and draw. However, pdflib is not free and the lite version is not allowed for commercial use. Resources — These are references to functions and resources outside of PHP.
The unlink function is dedicated for file system handling.
