The function accepts its parameters in any order. We learnt that the implode() function returns a string from the elements of an array. In this example, the values of the array $details were taken into account, while the keys were disregarded. Input: ?phpĮcho implode(',', $details) Output: Frank,Smith,Male The keys of the array will be ignored in this instance. If we pass an associative array to the implode function, then only the array’s values will be joined. This_is_PHP_simplified Joining elements of an associative array with the implode function $trial = array('This','is','PHP','simplified') Here is another example of joining the array elements with various characters. $sample_header = implode(' ', $column_heading) Įcho $sample_header Output: first_name age phone number address In this section, we look at an example of joining the string elements of an array into a new string. Joining strings using the implode function Let’s look at some examples of the implode function’s usage. Note: The separator parameter is optional, but recommended. The array whose value is to be joined to form the resultant string.If $separator is used, it defaults into an empty string. The separator is the character that separates two strings.This is the syntax of the function: implode(separator, array) You can read more about the explode function in PHP here Syntax of the PHP implode function In other words, it breaks a string into an array. However, the explode function splits the string into a specified number of pieces. The implode function returns the joined elements of an array as a string. What is the difference between the implode and explode functions in PHP? This is because they both achieve the same result. Note: The join() function is used interchangeably with the implode() function. And if the array is empty, then the implode() function will also return an empty string. The order of the elements in the resultant string is the same as the order they appear in the array. The implode() function returns a new string which is the result of joining the string elements in the array with the separator. What is the difference between explode and implode in PHP?.In this case, simply prepending/appending the separator next to implode() is not enough, so I made this little helper function. Sometimes it's necessary to add a string not just between the items, but before or after too, and proper handling of zero items is also needed.
