I have two Json arrays like below:
$a='[{"type":"text","req":0,"name":"user"},{"type":"text","req":0,"name":"org"},'
. '{"type":"textarea","label":"Notes","req":0},'
. '{"type":"text","label":"text1","req":0},'
. '{"type":"textarea","label":"Notes","req":0},'
. '{"type":"text","label":"text2","req":0},'
. '{"type":"textarea","label":"Notes","req":1}]';
$b='[{"type":"textarea","label":"Notes","Element_Values":"331","Element_Name":"textarea-710091","Count_Images":0},'
. '{"type":"text","label":"text1","Element_Values":"1","Element_Name":"text-987351","Count_Images":0},'
. '{"type":"textarea","label":"Notes","Element_Values":"332","Element_Name":"textarea-254458","Count_Images":0},'
. '{"type":"text","label":"text2","Element_Values":"2","Element_Name":"text-3410","Count_Images":0},'
. '{"type":"textarea","label":"Notes","Element_Values":"333","Element_Name":"textarea-554051","Count_Images":0}]';
As you can see array 'a' starts with few keys which is not in array 'b'. I want to skip the arrays which has 'name' keys.
I did the following code, but didnt work:
$c = [];
$aJson=json_decode($a, true);
$bJson=json_decode($b, true);
foreach($aJson as $key => $array)
{
foreach($array as $an)
{
if(array_key_exists('name', $an))
{
//continue;
}
}
$c[$key] = array_merge($bJson[$key],$array);
}
echo json_encode($c);
The result array c should be:
[{"type":"textarea","label":"Notes","Element_Values":"331","Element_Name":"textarea-710091","Count_Images":0,"req":0},{"type":"text","label":"text1","Element_Values":"1","Element_Name":"text-987351","Count_Images":0,"req":0},{"type":"textarea","label":"Notes","Element_Values":"332","Element_Name":"textarea-254458","Count_Images":0,"req":0},{"type":"text","label":"text2","Element_Values":"2","Element_Name":"text-3410","Count_Images":0,"req":0},{"type":"textarea","label":"Notes","Element_Values":"333","Element_Name":"textarea-554051","Count_Images":0,"req":1}]
Please help me
This is a simple debug problem, $array is already the array.
$index = 0;
foreach($aJson as $key => $array)
{
if(isset($array['name']))
continue;
$c[$index] = array_merge($bJson[$index], $array);
$index++;
}

I'm trying to handle the recursive array in PHP. But my code is working fine. Problem is I'm unable to store the results in one array and return.
See the code:
function array_recursion(array $myarray, array $searchterms){
//empty array
$tempArr = array();
//loop through $myarray
foreach ($myarray as $key => $value){
if (is_array($value)){
array_recursion($value, $searchterms);
}
else if (in_array($key, $searchterms)){
print str_replace("0:", "", ($key . ": " . $value . "\n"));
}
}
}
//Call the function
$finalValue = array_recursion($arr, Array('VCHKEY','VOUCHERTYPENAME','VOUCHERNUMBER','PARTYNAME','NARRATION','REFERENCE','AMOUNT','VCHTYPE'));
//but this should print empty array
print_r($finalValue);die();
I want to use the below two lines in the above function
$tempArr[] = str_replace("0:", "", ($key . ": " . $value . "\n"));
return $tempArr;
What is the actual issue? Can anyone help to figure it out? Thanks in advance.
Finally i found the solution to return the value as array using recursion method.Check the below code.
function array_value_recursive(array $key, array $arr){
$val = array();
array_walk_recursive($arr, function($va, $ke) use($key, &$val){
if(in_array($ke,$key))
array_push($val, $va);
});
return count($val) > 1 ? $val : array_pop($val);
}
Hope this will help someone.
I have an array like this $arr = Array ("A","E","I","O","U");
My question is using implode function how can I make the output like this
1.A
2.E
3.I
4.O
5.U
You need to iterate over each values like this:
$arr = array("A","E","I","O","U");
foreach ($arr as $key => $value) {
echo $key + 1 . ".{$value} <br>";
}
This will give you the desired Output as:
1.A
2.E
3.I
4.O
5.U
Hope this helps!
$i = 1;
foreach ($arr as $v) {
echo $i . '.' . $v . '<br>';
$i++;
}
no need to use implode function. Just use foreach loop to iterate whole array.
use array_walk to traverse the array like this:
array_walk($array, function($v, $k)
{
echo $k + 1 . '.' . $v . "<br>";
});
$array['a:b']['c:d'] = 'test';
$array['a:b']['e:f']= 'abc';
I need output like below. array can have multiple level . Its comes with api so we do not know where colon come.
$array['ab']['cd'] = 'test';
$array['ab']['ef']= 'abc';
(untested code) but the idea should be correct if want to remove ':' from keys:
function clean_keys(&$array)
{
// it's bad to modify the array being iterated on, so we do this in 2 steps:
// find the affected keys first
// then move then in a second loop
$to_move = array();
forach($array as $key => $value) {
if (strpos($key, ':') >= 0) {
$target_key = str_replace(':','', $key);
if (array_key_exists($target_key, $array)) {
throw new Exception('Key conflict detected: ' . $key . ' -> ' . $target_key);
}
array_push($to_move, array(
"old_key" => $key,
"new_key" => $target_key
));
}
// recursive descent
if (is_array($value)) {
clean_keys($array[$key]);
}
}
foreach($to_move as $map) {
$array[$map["new_key"]] = $array[$map["old_key"]];
unset($array[$map["old_key"]]);
}
}
try this:
$array=array();
$array[str_replace(':','','a:b')][str_replace(':','','c:d')]="test";
print_r($array);
This seems like the simplest and most performant approach:
foreach ($array as $key => $val) {
$newArray[str_replace($search, $replace, $key)] = $val;
}
I am trying to print an array using foreach and while printing, if a certain $key comes up, I want to make changes to the array. Problem is, even though the array gets changed, the changes do not get printed.
In the example below, you will find:
function I use to change the array;
an array first printed with no changed;
then echo print-out in with changes during the process - all using foreach;
another print-out of the same table, but this time with changes.
<?php
function insert_before_key($array, $key, $data = NULL){
if (($offset = array_search($key, array_keys($array))) === false){
$offset = count($array);
}
return array_merge(array_slice($array, 0, $offset), (array) $data, array_slice($array, $offset));
}
$array = array(
"no_color" => "blank",
"color1" => "red",
"color2" => "green",
"color3" => "blue",
);
echo "<pre>";
print_r($array);
echo "</pre>";
foreach ($array as $key => $value) {
echo $key . ": " . $value . "<br />";
if ($key === "color1"){
$array = insert_before_key($array, "color2", array("color1.5" => "yellow"));
}
}
echo "<pre>";
print_r($array);
echo "</pre>";
echo "<br />";
?>
Note that the new $key is to jump in AFTER current $key, so I would expect it to come up.
Any idea why this happens ?
EDIT:
Played a bit more with foreach and I think it must be caching the keys or something...
<?php
$test_array = array(0,1,2,3,4,5,6,7,8,9);
foreach ($test_array as $key => $value) {
if ($key === 5){$test_array[7] = $test_array[7]+1;}
echo $key . ": " . $value . "<br />";
}
print_r($test_array);
?>
The above will display UNCHANGED echo, but CHANGED print_r.
From the manual: "As foreach relies on the internal array pointer, changing it within the loop may lead to unexpected behavior." http://php.net/manual/en/control-structures.foreach.php
You shouldn't modify an array you're looping over.
So during iteration you are trying to change the value of the item being iterated
foreach($array ...)
{
change $array
}
Use a copy of $array inside the iteration
$array2 = $array
foreach($array ...)
{
change $array2
}
I'd keep it simple. Something tells me however that you're fixing effects of a problem here and not its source.
$array = array(
"no_color" => "blank",
"color1" => "red",
"color2" => "green",
"color3" => "blue",
);
$temp_array = array();
foreach ($array as $key => $value) {
$temp_array[$key] = $value;
echo $key . ": " . $value . "<br />";
if ($key == 'color1') {
$key_add = 'color1.5';
$value_add = 'yellow';
$temp_array[$key_add] = $value_add;
echo $key_add . ": " . $value_add . "<br />";
}
}
$array = $temp_array;
I have a multidimensional array in PHP, something that looks like:
array(array(Category => Video,
Value => 10.99),
array(Category => Video,
Value => 12.99),
array(Category => Music,
Value => 9.99)
)
and what I would like to do is combine similar categories and output everything into a table, so the output would end up being:
<tr><td>Video</td><td>23.98</td></tr>
<tr><td>Music</td><td>9.99</td></tr>
Any suggestions on how to do this?
EDIT:
I can have these in two different arrays if that would be easier.
A simple loop will do:
$array = [your array];
$result = array();
foreach ($array as $a) {
if (!isset($result[$a['Category']])) {
$result[$a['Category']] = $a['Value'];
} else {
$result[$a['Category']] += $a['Value'];
}
}
foreach ($result as $k => $v) {
echo '<tr><td>' . htmlspecialchars($k) . '</td><td>' . $v . '</td></tr>';
}
$result = array();
foreach ($array as $value) {
if (isset($result[$value['Category']])) {
$result[$value['Category']] += $value['Value'];
} else {
$result[$value['Category']] = $value['Value'];
}
}
foreach ($result as $category => $value) {
print "<tr><td>$category</td><td>$value</td></tr>";
}
