How to append one array to another without comparing their keys?
$a = array( 'a', 'b' ); $b = array( 'c', 'd' ); At the end it should be: Array( [0]=>a [1]=>b [2]=>c [3]=>d ) If I use something like [] or array_push, it will cause one of these results:
Array( [0]=>a [1]=>b [2]=>Array( [0]=>c [1]=>d ) ) //or Array( [0]=>c [1]=>d ) It just should be something, doing this, but in a more elegant way:
foreach ( $b AS $var ) $a[] = $var;

Given two array arr1 and arr2 and the task is to append one array to another array. Using array_merge function: This function returns a new array after merging the two arrays. $arr1 = array ( "Geeks" , "g4g" );
To append one array to another, call the concat() method on the first array, passing it the second array as a parameter, e.g. const arr3 = arr1. concat(arr2) . The concat method will merge the two arrays and will return a new array.
The getArrayCopy() function of the ArrayObject class in PHP is used to create a copy of this ArrayObject. This function returns the copy of the array present in this ArrayObject.
Definition and Usage. The array_push() function inserts one or more elements to the end of an array. Tip: You can add one value, or as many as you like. Note: Even if your array has string keys, your added elements will always have numeric keys (See example below).
array_merge is the elegant way:
$a = array('a', 'b'); $b = array('c', 'd'); $merge = array_merge($a, $b); // $merge is now equals to array('a','b','c','d'); Doing something like:
$merge = $a + $b; // $merge now equals array('a','b') Will not work, because the + operator does not actually merge them. If they $a has the same keys as $b, it won't do anything.
