Possible values: Greater than 0 - Returns an array with a maximum of limit element (s) Less than 0 - Returns an array except for the last -limit elements () 0 - Returns an array with one element. , string)) beforeDot current (explode ('.', string)) // PHP < 5.3: beforeDot explode ('.

It splits a string based on a specified separator that we pass as an. This article showed you how to use the explode() function in PHP. PHP explode() is a built-in function that is used to split a string into a string array. Important Note: The separator parameter can’t be an empty string. This common built-in function returns an array containing the strings formed by splitting the original string. this function splits the string while the delimiter character occurs. ![]() You can see that HTML and PHP got ptinted together because there was no space between them. The explode () function in PHP splits a string based on a string delimiter, i.e. 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. Apart 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. It splits a string based on a specified separator that we pass as an argument. Unlike implode() which works even if the separator is not provided, the explode() function won’t work without the separator. PHP explode () is a built-in function that is used to split a string into a string array. 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. If separator contains a value that is not contained in string and a negative limit is used, then an empty array will be returned, otherwise an array containing string will be returned. The documentation of explode() (, section "Return Values") however states that "If delimiter contains a value that is not contained in string, then explode() will return an array containing string", which then does not hold for negative limits.The PHP explode() function converts a string to an array. If separator is an empty string (''), explode () throws a ValueError. It appears that explode() returns an empty array (instead of an array with string in it) if limit is negative and delimiter contains a value that is not contained in string.
