Php explode test array12/18/2023 ![]() ![]() In the first array, since the limit value was less than the number of elements all the remaining elements were passed in the last element. Now let’s look at an example using the limit: In the above code block, since a limit was not passed the returned array contains a string with all the elements. The output of the above code snippet would be: Array If a limit value is passed, the return values would be based on that. If no limit argument is passed the string array would contain all the elements split by the separator. Zero - If zero is passed the element will contain only elements which would be the entire string.Negative Value - If a negative value is passed the last element will be trimmed off and the and the remaining part of elements would be returned as an array.In case the value is lesser than the number of elements in the array, the N-1th element of the string array would contain all the remaining elements. Positive Value - If a positive value is passed as a parameter, it denotes the number of elements the string array should contain.Limit - Optional, used to specify the number of elements in the string array.String - Required, the string that you want to split. ![]() Separator - Required, used to specify where the string should be split. ![]() Syntax of PHP explode: explode(separator, string,limit) It splits a string based on a specified separator that we pass as an argument.Īpart from this functionality, the explode method also has a third parameter, “ limit” that can be used to manipulate the number of elements in the array. If you don’t specify a separator, explode() won’t work as expected.PHP explode () is a built-in function that is used to split a string into a string array. 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. ![]()
