![]() ![]() ![]() The syntax of the str_split() function is: It does not use any kind of separator, it just splits the string. ![]() This is an in-built PHP method that is used to convert a string into an array by breaking the string into smaller sub-strings of uniform length and storing them in an array. The first method in this list is str_split(). There are various approaches, including in-built functions and manual approaches that are used to convert string to array in PHP. This article explains several approaches to achieve this task.įollowing is the complete list of methods that can be used in PHP to convert a string to an array.ĭifferent Methods to Convert String to Array in PHP Being a powerful scripting language, PHP provides various in-built methods to convert a string to an array. When you convert a string into an array, it makes data manipulation convenient. Arrays can help you implement better data organization and faster operations. This provides more security and ease of access to the data. For instance, you can convert the passwords entered as input in a web application into an array before storing them in the database. There are many cases when an array is considered more suitable over a string. If you use -2 instead of – 1 for the $limit, the explode() function will remove the last 2 elements.Why Do You Need to Convert a String to an Array in PHP? Also, it excludes the last element from the result array. In this example, the explode() function returns an array of the string split by the comma ( ,). The following example uses the explode() function with the a negative $limit argument: $str = 'first_name,last_name,email,phone' 3) Using the PHP explode() function with a negative $limit Also, the last element has the remaining string. Var_dump($headers) Code language: PHP ( php )Īs shown clearly in the output, the returned array contains three elements specified by the $limit argument. The following example uses the explode() function with the a positive $limit argument: $str = 'first_name,last_name,email,phone' } Code language: PHP ( php ) 2) Using the PHP explode() function with a positive $limit The following example uses the explode() function to split a string by a comma ( ,): string( 10) "first_name" 1) Simple the PHP explode() function example Let’s take some examples of using the explode() function. Starting from PHP 8.0.0, the explode() function throws a ValueError instead. Prior to PHP 8.0.0, the explode() function returns false if the $separator is an empty string. Also, it removes the last $limit elements from the result array. If the $limit is negative, the explode() function splits the $string using the $separator. So the function returns an array with the original string. If the $limit is zero, explode() function interprets it as one. If the $limit is positive, the explode() function returns an array with $limit elements where the last element containing the rest of the string. $limit specifies how the function will return the result array.$separator is the delimiter that the explode() function uses to split the $string.The explode() function has the following parameters: The following shows the syntax of the explode() function: explode ( string $separator, string $string, int $limit = PHP_INT_MAX ) : array Code language: PHP ( php ) The PHP explode() function returns an array of strings by splitting a string by a separator. Introduction to the PHP explode() function Summary: in this tutorial, you’ll learn how to use the PHP explode() function to split a string by a separator into an array of strings. ![]()
