This function returns a string containing all the elements of input array in the same order, along with separator(if specified). The separator parameter in implode() function became optional in PHP version 4.3.0, but it is recommended to use atleast two-parameter for backward compatibility.PHP implode() accepts its parameter in either order.This parameter specifies the array whose elements are to be imploded (joined) This parameter separates the elements of an array joined to form a string. The implode() function takes two parameters one optional and one compulsory. It merges all the elements of an array and returns a string. And this function is binary-safe, where it treats its input as a raw stream of bytes and ignores every textual aspect it may have.The implode() function is a binary-safe function in PHP, which used to join elements of an array. However, for consistency with the explode() function we must use the documented order of arguments. 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. Using PHP to implode an array into a string can be helpful in several cases. In addition, it features a parameter that allows you to control the separator used between each element. The function achieves this by joining each array element together. This_is_PHP_simplified Joining elements of an associative array with the implode function In PHP, the implode function allows you to take an array and convert it to a string. $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. implode Join array elements with a string Description implode ( string separator, array array ): string Alternative signature (not supported with named arguments): implode ( array array ): string Legacy signature (deprecated as of PHP 7.4.0, removed as of PHP 8.0. Joining strings using the implode function There are two approaches to this: 1) Combine only values to string This is very simple since implode () function only considers array item's value and not index. ![]() Let’s look at some examples of the implode function’s usage. The implode () function can not only join arrays with integer index but with string index as well, which we call it as associative arrays. Note: The separator parameter is optional, but recommended.
