How to merge multiple arrays from a single array variable ? lets say i have this in one array variable
Those are in one variable ..
$array = array(array(1), array(2));
Array
(
[0] => 1
)
Array
(
[0] => 2
)
how to end up with this
Array
(
[0] => 1
[1] => 2
)
This is the PHP equivalent of javascript Function#apply (generate an argument list from an array):
$result = call_user_func_array("array_merge", $input);

result key, you need to map each element to its only element first. In 5.3+ you can write $input = array_map(function(x){return x['result']}, $input)Since PHP 5.6 you can use variadics and argument unpacking.
$result = array_merge(...$input);
It's up to 3x times faster than call_user_func_array.
This may work:
$array1 = array("item1" => "orange", "item2" => "apple", "item3" => "grape");
$array2 = array("key1" => "peach", "key2" => "apple", "key3" => "plumb");
$array3 = array("val1" => "lemon");
$newArray = array_merge($array1, $array2, $array3);
foreach ($newArray as $key => $value) {
echo "$key - <strong>$value</strong> <br />";
}
array_merge can do the job
$array_meged = array_merge($a, $b);
after the comment
If fixed indexs you can use:
$array_meged = array_merge($a[0], $a[1]);
A more generic solution:
$array_meged=array();
foreach($a as $child){
$array_meged += $child;
}
$resultArray = array_merge ($array1, $array1);
$result = array();
foreach ($array1 as $subarray) {
$result = array_merge($result, $subarray);
}
// Here it is done
Something good to read: https://www.php.net/manual/en/function.array-merge.php
Recursive:
https://www.php.net/manual/en/function.array-merge-recursive.php
array_merge to the array. See my answer.$arr1 = array(0=>1);
$arr2 = array(0=>2);
$merged = array_merge($arr1,$arr2);
print_r($merged);
array_merge is what you need.
$arr = array_merge($arr1, $arr2);
Edit:
$arr = array_merge($arr1[0], $arr1[1]);
$arr1?
