Ok , so I have a $unique_answer_title contains multiple arrays. Below is what I get when I use var_dump($unique_answer_title):
array(4) { [0]=> string(9) "Immediate" [1]=> string(3) "Yes" [2]=> string(29) "Have a representative call me" [3]=> string(109) "Biomek<sup><em>‡‡</em></sup> FX<sup>P</sup> Workstation" } array(8) { [0]=> string(9) "Immediate" [1]=> string(3) "Yes" [2]=> string(29) "Have a representative call me" [3]=> string(109) "Biomek<sup><em>‡‡</em></sup> FX<sup>P</sup> Workstation" [4]=> string(9) "Immediate" [5]=> string(2) "No" [6]=> string(29) "Have a representative call me" [7]=> string(111) "Biomek<sup><em>‡‡</em></sup> NX<sup>P</sup> Workstation " } array(12) { [0]=> string(9) "Immediate" [1]=> string(3) "Yes" [2]=> string(29) "Have a representative call me" [3]=> string(109) "Biomek<sup><em>‡‡</em></sup> FX<sup>P</sup> Workstation" [4]=> string(9) "Immediate" [5]=> string(2) "No" [6]=> string(29) "Have a representative call me" [7]=> string(111) "Biomek<sup><em>‡‡</em></sup> NX<sup>P</sup> Workstation " [8]=> string(20) "Greater than 3 years" [9]=> string(3) "Yes" [10]=> string(42) "Have a representative contact me via email" [11]=> string(109) "Biomek<sup><em>‡‡</em></sup> FX<sup>P</sup> Workstation" } array(18) { [0]=> string(9) "Immediate" [1]=> string(3) "Yes" [2]=> string(29) "Have a representative call me" [3]=> string(109) "Biomek<sup><em>‡‡</em></sup> FX<sup>P</sup> Workstation" [4]=> string(9) "Immediate" [5]=> string(2) "No" [6]=> string(29) "Have a representative call me" [7]=> string(111) "Biomek<sup><em>‡‡</em></sup> NX<sup>P</sup> Workstation " [8]=> string(20) "Greater than 3 years" [9]=> string(3) "Yes" [10]=> string(42) "Have a representative contact me via email" [11]=> string(109) "Biomek<sup><em>‡‡</em></sup> FX<sup>P</sup> Workstation" [12]=> string(9) "Immediate" [13]=> string(2) "No" [14]=> string(15) "Send literature" [15]=> string(77) "Sign me up for more info on the Biomek 4000<sup>†</sup>."

How can I combine all the elements of these arrays shown below into one numerical array?
array_merge($unique_answer_title) doesn't seem to work ... and the variable $unique_answer_title itself is not an array, it's a group of multiple arrays. How can I get the elements of all these individual arrays together into one big array?

Answer 1

You need to merge the single arrays in a foreach loop.
$mergedArray = array();
foreach($unique_answer_title as $single){
$mergedArray = array_merge($mergedArray, $single);
}
