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 If you don’t specify a separator, explode() won’t work as expected.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. Note that unlike implode() which works without the separator, the separator is very important in explode(). This article showed you how to use the explode() function in PHP. You can see that HTML and PHP got ptinted together because there was no space between them. If you type two different words together, they are treated as one: $str = "CSS HTMLPHP Java JavaScript" The explode() function looks at spaces in the string to split the string into an array. The index is not more than the limit of 2 specified. You can see that the first element takes an index of 0 and the rest of the comma-separated elements take 1. $str = "CSS, HTML, PHP, Java, JavaScript" For example, if you specify 2, all the strings would show, but the index won’t be more than 2. If you specify a limit in the explode() function, the index(es) won’t be more than that number. We are printing an array, so we can use print_r() Remember that arrays use zero-based indexing. If the string is passed into an explode() function, Hello takes an index of 0 in the array, and World takes an index of 1. Let's say that I have the string "Hello World". You can use the limit parameter to specify the number of arrays expected. So, just like the string split into an array, the separator is required. Unlike implode() which works even if the separator is not provided, the explode() function won’t work without the separator. The full syntax looks like this: explode(separator, string, limit) The explode() function takes in three parameters: Like the built-in implode() function, the explode function does not modify the data (string). Each of the characters in the string is given an index that starts from 0. The PHP explode() function converts a string to an array.
