Find String in Array Value and Move Position. How?

[virginiamonkeys]

I have a multidimensional array with values as such:

array(4) {
  [0]=>
  array(7) {
    [0]=>
    string(xx) "sample *catchword* sample"
    [1]=>
    string(xx) "test *catchword*"
    [2]=>
    string(xx) "text here catchword *catchword* text here"
    [3]=>
    string(xx) "just regular text"
    [4]=>
    string(xx) "*catchword* and text"
    [5]=>
    string(xx) ""
    [6]=>
    string(xx) "more *catchword* text"
  [1]=>
  array(7) {
    [0]=>
    string(xx) "sample *catchword* sample"
    [1]=>
    string(xx) "test *catchword*"
    [2]=>
    string(xx) "text here catchword *catchword* text here"
    [3]=>
    string(xx) "just regular text"
    [4]=>
    string(xx) "*catchword* and text"
    [5]=>
    string(xx) ""
    [6]=>
    string(xx) "more *catchword* text"
  [2]=>
  array(7) {
    [0]=>
    string(xx) "sample *catchword* sample"
    [1]=>
    string(xx) "test *catchword*"
    [2]=>
    string(xx) "text here catchword *catchword* text here"
    [3]=>
    string(xx) "just regular text"
    [4]=>
    string(xx) "*catchword* and text"
    [5]=>
    string(xx) ""
    [6]=>
    string(xx) "more *catchword* text"
  [3]=>
  array(7) {
    [0]=>
    string(xx) "sample *catchword* sample"
    [1]=>
    string(xx) "test *catchword*"
    [2]=>
    string(xx) "text here catchword *catchword* text here"
    [3]=>
    string(xx) "just regular text"
    [4]=>
    string(xx) "*catchword* and text"
    [5]=>
    string(xx) ""
    [6]=>
    string(xx) "more *catchword* text"

I want to take every instance of *catchword* and move it to the end of each string. For instance, the 1st result would reposition as "sample sample *catchword*".

I don't know where to start looking.

First write a function that'll move the instance to the end of a string.
Then apply that function to the array using array_walk_recursive

That's what I plan but I can't think of the function(s) in the php manual I need to look up to find the string, then to move it.

you could use explode() to seperate the string into words
then use array_search() to find if the string exists in one of the array elements. If so, unset() it and then append it to the end of the array.
implode() it back together.

I don't know what's wrong with me today.

I several things to find recursively. This is the latest version of my code:

function find_phrase(&$item, $key)
{
 $found = (array_keys($found, "catchphrase"));
}
array_walk_recursive($array, 'find_phrase');

var_dump($found); 

I'm getting nowhere.

Simplify your problem and take it in steps. Write a function that works for a single string only, and make it work real good. Then, worry about dealing with arrays.

That's what I've been trying to do for the last 2 days. I'm getting slightly frustrated. This just isn't working at all for me.
