In PHP, an indexed array is what it sounds like – each value in the array has an index automatically assigned to it. Examples of Implode with an Indexed Array In the syntax above, an empty space (" ") is the separator, and $array is the array.

The full syntax of an implode() looks like this: implode(" ", $array) NB: implode() doesn’t work with nested arrays. The array on the other hand could be an associative array or an indexed array. If you don’t pass in the separator, implode() still works. It is valid as long as you specify it in quotes. The separator could be any character or an empty string. Implode() takes in two values as parameters – the separator and the array you want to convert to a string. Once you pass in the array to implode(), it joins all the values to a string. It doesn’t matter whether the array is an indexed or associative array.
implode() doesn’t modify the original array. I hope this helps atleast one person for all that I've gained from this site.In PHP, the implode() function is a built-in function that takes an array and converts it to a string. The function will also do the reverse and add a multi to a single dimensional array or even a 2 tier array to a 5 tier as long as the heirarchy tree is identical. This is will replace the value for "food" for "dewberry" with "wine". $array1 = polecat_array_replace ( $array1, $array2 ) array( "strawberry" => array( "color" => "red", "food" => "desserts" ), "dewberry" = array( "color" => "dark violet", "food" => "pies" ), ) that if you want to add a single dimensional array to a multi, all you must do is pass the matching internal array key from the multi as the initial argument as such: Since this site has helped me so much, I felt the need to return the favor. With PHP 5.3 still unstable for Debian Lenny at this time and not knowing if array_replace would work with multi-dimensional arrays, I wrote my own. A simple logical step was all that was needed. The enviroment I was coding in never called it more than once but I caught it in testing and here is the fully working revision. When the function was called more than once, it threw a function redeclare error of course. I hope that this will save someone's time. output -> name: some name, json:, title: some title
# usage of array_replace to get exact order and save the day output -> name: some name, json: some title, title: $test = array_intersect_key ( $arr, $keys ) use it with a vsprintf, you could use the following Now consider that you want to capture $arr values from $keys.Īssuming that you have a limitation to display the content into given keys $keys = array( 'name', 'json', 'title' ) # capture these keys values into given order In some cases you might have a structured array from the database and one
