将字符串添加到数组PHP

Question

Hello I have $string1, Array[] and $string2. I want to create a Arraynew[] such that

Arraynew[0]=$string1
Arraynew[1]=Array[0]
.
.
.
Arraynew[n-1]=Array[n]
Arraynew[n]=$string2

The problem being that I don't know how many elements are in Array[] since it's from parsed data that changes and also I don't know how to formulate the above correctly in PHP.

Please help me.

Thank you.

Answer 1

array_unshift() will insert one or more elements at the beginning of the array. array_push() will add one or more elements to the end of the array. So:

$new_array = $array;
array_unshift($new_array, $string1);
array_push($new_array, $string2);

Answer 2

In addition to the excellent answer from cletus here are a couple of more ways:

$new_array = array($string1, $string2);
array_splice($new_array, 1, 0, $array);

// Or

$new_array = array_merge((array) $string1, $array, (array) $string2);
