I have two arrays populated from CodeIgniter query result sets (from calls of result_array()
) and I need to merge the rows from the two arrays respectively/synchronously.
$array1 = [
['name' => 'John', 'course' => 'BSIT'],
['name' => 'Jane', 'course' => 'BSHRM'],
];
$array2 = [
['balance' => '1000', 'date' => '2013-05-01'],
['balance' => '2000', 'date' => '2013-05-07'],
];
How can I append the elements [balance], [date]
from $array2
to $array1
so that the result looks like this:
[
[
'name' => 'John',
'course' => 'BSIT',
'balance' => '1000',
'date' => '2013-05-01'
],
[
'name' => 'Jane',
'course' => 'BSHRM',
'balance' => '2000',
'date' => '2013-05-07'
]
]
I have tried:
for($i = 0; $i<count($array1); $i++)
{
array_merge($array1[$i], $array2[$i]);
}
but I get an error that arguments are not array
even if I do it like this:
for($i = 0; $i<count($array1); $i++)
{
array_merge(array($array1[$i]), array($array2[$i]));
}
Try setting the array_merge equal to something:
for($i = 0; $i<count($array1); $i++)
{
$array1[$i] = array_merge($array1[$i], $array2[$i]);
}
$merged_array = array_map(function($a, $b) {
return array_merge($a, $b);
}, $array1, $array2));
尝试使用array_merge_recursive()函数
There is a simpler way to merge the rows of two or more arrays. Call array_map()
with a callback of array_merge()
and then list the arrays as final function parameters. array_map()
will synchronously isolate one row at a time from the input arrays so that array_merge()
can combine the two rows into one.
Code: ( Demo )
var_export(
array_map('array_merge', $array1, $array2)
);
