Listing 7-1 - A Sample indexSuccess.php TemplateĪs explained in Chapter 4, the alternative PHP syntax is preferable for templates to make them readable for non-PHP developers. It contains some HTML code and some basic PHP code, usually calls to variables defined in the action (via $this->name = 'foo' ) and helpers. Listing 7-1 shows a typical symfony template. When dealing with variables in the templates, the risks of cross-site scripting must not be ignored, and a good comprehension of output escaping techniques is required to safely record user data.īut whatever your role is, you will find useful tools to speed up the tedious job of presenting the results of the action. Developers focus on the YAML view configuration file (setting the properties of the response and other interface elements) and on the response object.Web designers can work on these template fragments as well. They use slots to affect more than one zone of the layout. For reusability, developers usually package template code fragments into partials or components.These are written in HTML with small embedded chunks of PHP, which are mostly calls to helpers. Web designers generally work on the templates (the presentation of the current action data) and on the layout (containing the code common to all pages).In symfony, the view consists of several parts, with each part designed to be easily modified by the person who usually works with it. Thank you all, I hope my article was of some help to you.The view is responsible for rendering the output correlated to a particular action. Preg_split(string $pattern, string $subject, int $limit = -1, int $flags = 0): array|falseĪs you can see in this example, my string is split into an array using the pattern \s which means space.Īs a result, colleagues, today we considered the possibility of splitting a string into an array using simple functions built into the php language itself. I recommend that you use the explode function in your projects because it will be faster than the preg_split function. The second function to help us split a string into an array is called preg_split. The function splits a string into an array, specifying a regular expression. The preg_split function takes four parameters, two required and two optional parameters. In the first parameter, we need to specify the so-called template by which the string will be split into an array, and the second parameter is the string itself. If the parameters are passed correctly, then the function will return an array, otherwise it will return false. The first function we'll talk about is called explode. The function splits the string into an array with a delimiter. The explode function takes two required parameters and one optional, the first parameter is the split with which the php interpreter will understand how to split the string into an array, and the second parameter is the string itself. The function, as you already understood, returns an array.Įxplode(string $separator, string $string, int $limit = PHP_INT_MAX): arrayĪs you can see in the example, my string is split into an array using a space separator as the first parameter. ![]() ![]() In this article, we will talk about what are some simple functions built into PHP itself that will help you split a string into an array without any difficulties. In my example, I will split the string into an array using a space separator as the passed function parameter. ![]() ![]() Every web developer in his robot will sooner or later face such a task as splitting a string into an array in the PHP programming language. One example of why you might want to split a string into an array is when you get a string from a database about a user's date of birth, and you need to split this string into a year, month, and day using some sort of delimiter.
