Hi, I am trying to get two arrays elements with the same key to me merged together.
array1 = array(0=>"1", 1=>"2", 2=>"3");
array2 = array(0=>"a", 1=>"b", 2=>"c");
foreach ($array1 as $origKey => &$subArray)
foreach ($array2[$origKey] as $key => $val)
$subArray[$key] = $val;
The ouptut required:
array(0=>"1a", 1=>"2b", 2=>"3c")
Can somebody help me, please?
Use the following function to combine values
function combineValues($a1, $a2){
foreach ($a1 as $k => $v)
$r[$k] = $v . $a2[$k];
return $r;
}
<?
$array1 = array(0=>"1", 1=>"2", 2=>"3");
$array2 = array(0=>"a", 1=>"b", 2=>"c");
foreach ($array1 as $origKey => &$subArray)
$new[] = $subArray.$array2[$origKey];
print_r($new);
//Output: Array ( [0] => 1a [1] => 2b [2] => 3c )
Here you go:
<?php
$array1 = array(0=>"1", 1=>"2", 2=>"3");
$array2 = array(0=>"a", 1=>"b", 2=>"c");
$sub = [];
foreach ($array1 as $key => $value) {
array_push($sub, $value.$array2[$key]);
}
var_dump($sub);
->
array(3) {
[0]=>
string(2) "1a"
[1]=>
string(2) "2b"
[2]=>
string(2) "3c"
}
your this statement foreach ($array2[$origKey] as $key => $val) is wrong
that part $array[$origkey] coz in foreach $key as $value this basically evaluates whole array so use this way ....
<?php
$array1 = array(0=>"1", 1=>"2", 2=>"3");
$array2 = array(0=>"a", 1=>"b", 2=>"c");
$array3 = array();
for($i=0 ;$i<3 ;$i++)
{
$array3[] = $array1[$i].$array2[$i];
}
foreach($array3 as $merge)
{
echo $merge."<br>";
}
?>
let's get to the point, this will only work for a 1 dimension arrays of any lenghts :
$concatted_array = array(); // the new array
// if the 2 arrays don't have te same lenght, get the largest array
$max_array_length = (count($array1) > count($array2)) ? count($array1) : count($array1);
// loop for the longest array
for ($i=0; $i <$max_array_length ; $i++) {
if($i < count($array1) && $i < count($array2)) // if the element exist for both arrays
{
$concatted_array[$i] = $array1[$i].$array2[$i];
} elseif($i < count($array1)) // if element only exists in $array1
{
$concatted_array[$i] = $array1[$i];
} else // if element only exists in $array2
{
$concatted_array[$i] = $array2[$i];
}
}
var_dump($concatted_array);
Here is the output :
array (size=3)
0 => string '1a' (length=2)
1 => string '2b' (length=2)
2 => string '3c' (length=2)
Now here are some tips just in case you had errors with the code you wrote :
$ before variables.foreach should be used only on arrays or object, so don't do foreach ($array2[$origKey] as $key => $val) unless $array2[$origKey] is an array or object itself. visit foreach documentation for more info.
foreach ($array1 as $origKey => &$subArray) $subArray .= $array2[$origKey];
