php loop through complex posts - php

I am new to web programming and I have such a complex posts all over my work this was the result for a var_dump($_POST) , I am using gettype() function to determine that if the value in the $arr array is another array or not , I am not convenient of such behave of code of mine , neither the problems that I always met when going to loop for insertion
the question is if there is smarter technique to loop within like this complex posts , secondly how to catch the name,phone in the 2d array that called assistant (called assistant['name'],assistant[phone])
<?php
$arr = array(
"name"=> "mmmkkkk",
"phones"=> array(
"01553338897" ,
"09090909098"
),
"address"=> "107 ostras., Germany",
"assistant"=> array(
"name" => array(
"kmkkm",
"komar"
),
"phone"=> array(
"01043338897" ,
"09099090090"
)
)
);
foreach($arr as $key => $p_value)
{
if(gettype($p_value)=="array")
{
echo $key.":"."</br>";
foreach($p_value as $newp_value => $val )
{
if(gettype($val)=="array")
{
foreach($val as $vkey)
{
echo $vkey."</br>";
}
}
else{echo $val."</br>";}
}
}else{echo $key.":".$p_value."</br>";}
}
?>

You can use Recursive function like this.
<?php
$arr = array(
"name"=> "mmmkkkk",
"phones"=> array(
"01553338897" ,
"09090909098"
),
"address"=> "107 ostras., Germany",
"assistant"=> array(
"name" => array(
"kmkkm",
"komar"
),
"phone"=> array(
"01043338897" ,
"09099090090"
)
)
);
function rec($arr) {
foreach($arr as $key => $p_value)
{
if (is_array($p_value)) {
rec($p_value);
} else {
echo $key.":".$p_value."\n";
}
}
}
rec($arr);
?>

Think recursive
function walkThrough($array, $tabulation = 0) {
foreach($array as $key => $value) {
printf ('%s%s:', str_repeat(4*$tabulation, ' '));
if (is_array($value)) walkThrough ( $value, ($tabulation+1) );
else printf('%s<br />', $value);
}
}

Use this Recursive function
function recursivefunc($arr,$key =''){
if(is_array($arr)){
foreach($arr as $k => $v){
if (is_array($v) && !empty($v)) {
recursivefunc($v,$k);
} else {
$keys = ($key=='') ? $k : $key;
echo $keys.":".$v.'</br>';
}
}
}
}
recursivefunc($arr);
Out put :
name:mmmkkkk
phones:01553338897
phones:09090909098
address:107 ostras., Germany
name:kmkkm
name:komar
phone:01043338897
phone:09099090090

php - compare multi arrays and output in order

I have two arrays:
Array 1:
$art_style = ['Title1','Title2','Title3'];
Array 2:
array(
'name' => array('Title1', 'Title3', 'Title2'),
'value' => array('2,0x1,0', '2,5', '15,0'
);
I need to compare Array 2 "name" with Array 1 and output the values from Array 2 in the order of Array 1.
So the output in this case would be:
2,0x1,0 - 15,0 - 2,5
Any Idea how I could achieve that?
Try something like this:
// Array1 order
foreach ($art_style as $key => $value) {
if(in_array($value,$array2['name']))
echo $array2['value'][$key];
}
// Array2 order
foreach ($array2['name'] as $key => $value) {
if(in_array($value,$art_style))
echo $array2['value'][$key];
}
Little Long Method. But, It Worked.
<?
$array1 = ['Title1','Title2','Title3'];
$array2=array(
'name' => array('Title1', 'Title3', 'Title2'),
'value' => array('2,0x1,0', '2,5', '15,0')
);
$SizeofArray2=sizeof($array2['name']);
for($i=0;$i<$SizeofArray2;$i++)
{
$Array2Value= $array2['name'][$i];
for($j=0;$j<sizeof($array1);$j++)
{
if($Array2Value==$array1[$j])
{
if($j==$i)
{
echo " ".$array2['value'][$i];
}
if($j!=$i)
{
echo " -".$array2['value'][$i];
}
}
}
}
?>
Output: 2,0x1,0 -2,5 -15,0
try this:
$art_style = array('Title1','Title2','Title3');
$array2 = array(
'name' => array('Title1', 'Title3', 'Title2'),
'value' => array('2,0x1,0', '2,5', '15,0')
);
foreach ($art_style as $style) {
foreach ($array2['name'] as $id => $name) {
if ($name == $style) {
echo $array2['value'][$id].' - ';
break;
}
}
}

Outputting Array Keys of Multi-Dimensional Array

I'm trying to write a function that takes a multi-dimensional array as input and outputs a multi-line string of keys like the following
['key']['subkey']
['key']['another_subkey']
['key']['another_subkey']['subkey_under_subkey']
['key']['yet_another_subkey']
['another_key']['etc']
Here is my attempt. It has problems when you get to the second level.
function get_array_keys_as_string($array){
$output = "";
foreach($array as $k => $v){
if(is_array($v)){
$string = get_array_keys_as_string($v);
$prepend = "['$k']";
$string = $prepend.str_replace("\n","\n".$prepend, $string);
$output .= $string;
}
else{
$output .= "['$k']\n";
}
}
return $output;
}
I know I need a recursive function, but so far my attempts have come up short.
To get the exact output you asked for use the following:
$arr = array(
"key" => array(
"subkey" => 1,
"another_subkey" => array(
"subkey_under_subkey" => 1
),
"yet_another_subkey" => 1
),
"another_key" => array(
"etc" => 1
)
);
function print_keys_recursive($array, $path = false) {
foreach($array as $key=>$value) {
if(!is_array($value)) {
echo $path."[".$key."]<br/>";
} else {
if($path) {
echo $path."[".$key."]<br/>";
}
print_keys_recursive($value, $path."[".$key."]");
}
}
return;
}
print_keys_recursive($arr);
Output:
[key][subkey]
[key][another_subkey]
[key][another_subkey][subkey_under_subkey]
[key][yet_another_subkey]
[another_key][etc]
Not sure how you want the output since you have not provided an example array, just the result, but here is an example based on the following array,
$array = array(
"key" => array(
"subkey" => 1,
"another_subkey" => array("2", "subkey_under_subkey" => 3),
"yet_another_subkey" => 4
),
"another_key" => array("etc"),
"last_key" => 0
);
Using the following function,
function recursive_keys($arr, $history = NULL)
{
foreach ($arr as $key => $value)
{
if (is_array($value))
recursive_keys($value, $history."['".$key."']");
else
echo $history."['".$key."']\n";
}
}
Output of recursive_keys($array) is,
['key']['subkey']
['key']['another_subkey']['0']
['key']['another_subkey']['subkey_under_subkey']
['key']['yet_another_subkey']
['another_key']['0']
['last_key']
Try this
function arrayMultiKeys($array,$depth = 0){
foreach($array as $k=>$v){
echo "['".$k."']";
if(is_array($v)){
arrayMultiKeys($v,$depth + 1);
}
if($depth == 0 ){
echo "<br>";
}
}
}

PHP - Arrays and Foreach

I searched in Google and consulted the PHP documentation, but couldn't figure out how the following code works:
$some='name=Licensing Module;nextduedate=2013-04-10;status=Active|name=Test Addon;nextduedate=2013-04-11;status=Active';
function getActiveAddons($somet) {
$addons = array( );
foreach ($somet as $addon) {
if ($addon['status'] == 'Active') {
$addons[] = $addon['name'];
continue;
}
}
return $addons;
}
echo (count( getActiveAddons( $some ) ) ? implode( '<br />', getActiveAddons( $some ) ) : 'None');
The code always echo's None.
Please help me in this.
I don't know where you got this code from but you've initialized $some the wrong way. It is expected as an array like this:
$some = array(
array(
'name' => 'Licensing Module',
'nextduedate' => '2013-04-10',
'status' => 'Active'
),
array(
'name' => 'Test Addon'
'nextduedate' => '2013-04-11',
'status' => 'Active'
)
);
I guess the article you've read is expecting you to parse the original string into this format.
You can achieve this like this:
$string = 'name=Licensing Module;nextduedate=2013-04-10;status=Active|name=Test Addon;nextduedate=2013-04-11;status=Active';
$result = array();
foreach(explode('|', $string) as $record) {
$item = array();
foreach(explode(';', $record) as $column) {
$keyval = explode('=', $column);
$item[$keyval[0]] = $keyval[1];
}
$result[]= $item;
}
// now call your function
getActiveAddons($result);
$some is not an array so foreach will not operate on it. You need to do something like
$some = array(
array(
'name' => 'Licensing Module',
'nextduedate' => '2013-04-10',
'status' => 'Active'
),
array(
'name' => 'Test Addon',
'nextduedate' => '2013-04-11',
'status'=> 'Active'
)
);
This will create a multidimensional array that you can loop through.
function getActiveAddons($somet) {
$addons = array( );
foreach ($somet as $addon) {
foreach($addon as $key => $value) {
if ($key == 'status' && $value == 'Active') {
$addons[] = $addon['name'];
continue;
}
}
}
return $addons;
}
First, your $some variable is just a string. You could parse the string into an array using explode(), but it's easier to just start as an array:
$some = array(
array(
"name" => "Licensing Module",
"nextduedate" => "2013-04-10",
"status" => "Active",
),
array(
"name" => "Test Addon",
"nextduedate" => "2013-04-11",
"status" => "Active",
)
);
Now, for your function, you are on the right track, but I'll just clean it up:
function getActiveAddons($somet) {
if (!is_array($somet)) {
return false;
}
$addons = array();
foreach ($somet as $addon) {
if ($addon['status'] == 'Active') {
$addons[] = $addon['name'];
}
}
if (count($addons) > 0) {
return $addons;
}
return false;
}
And finally your output (you were calling the function twice):
$result = getActiveAddons($some);
if ($result === false) {
echo "No active addons!";
}
else {
echo implode("<br />", $result);
}

Combine repeating elements as array in a multidimensional array

I was wondering when working with multimedional arrays, if a certain key is the same, is there a way to combine the contents of other keys into its own array if a certain key is the same?
Something like this:
// name is the same in both arrays
array(
array(
'name' => 'Pepsi',
'store' => 'Over here',
'number' => '1234567'
),
array(
'name' => 'Pepsi',
'store' => 'Over here',
'number' => '5556734'
)
)
into something like this
array(
array(
'name' => 'Pepsi',
'store' => array('Over here', 'Over here'),
'number' => array('1234567', '5556734')
)
)
The defining key is checking if the name element is the same for the other arrays.
You can try a function like this.
function mergeByKey($array,$key){
$tmp_array = array();
foreach ( $array as $k => $row ) {
$merged = false;
foreach ($tmp_array as $k2 => $tmp_row){
if ($row[$key] == $tmp_row[$key]){
foreach ( $row as $k3 => $value ) {
if ($k3 == $key) continue;
$tmp_array[$k2][$k3][] = $value;
$merged = true;
}
}
if ($merged) break;
}
if (!$merged) {
$new_row = array();
foreach ( $row as $k4 => $value ) {
if ($k4 == $key) $new_row[$k4] = $value;
else $new_row[$k4] = array($value);
}
$tmp_array[] = $new_row;
}
}
foreach ( $tmp_array as $t => $row ) {
foreach ( $row as $t2 => $value ) {
if ( count($value) == 1 && $t2 != $key ) $tmp_array[$t][$t2] = $value[0];
}
}
return $tmp_array;
}
passing the array as first parameter and the key as second one.
I'm referencing to your array structure
edited: missed a piece
edited2: if resultin array contains elements with one string, it returns a string and not a array with one element
demo
This function uses a given field name as the grouping identifier and turns all other fields into arrays.
Note that single occurrences of your field name will yield arrays with a single element for the other fields. I wasn't sure whether that's a desirable trait, but just making sure you know ;-)
$arr = array(
array(
'name' => 'Pepsi',
'store' => 'Over here',
'number' => '1234567'
),
array(
'name' => 'Pepsi',
'store' => 'Over here',
'number' => '5556734'
)
);
function mergeArray($array, $column)
{
$res = array();
foreach ($array as $item) {
foreach ($item as $key => $value) {
if ($key === $column) {
$res[$column][$key] = $value;
} else {
$res[$column][$key][] = $value;
}
}
}
return array_values($res);
}
print_r(mergeArray($arr, 'name'));
Demo
Thanks to Gianni Lovece for her answer but I was able to develop a much simpler solution based on this problem. Just plug in the $result_arr to browse through and the $key you want to use as basis and it immediately outputs a multidimensional array with non-repeating values for repeating elements (see example below).
function multiarray_merge($result_arr, $key){
foreach($result_arr as $val){
$item = $val[$key];
foreach($val as $k=>$v){
$arr[$item][$k][] = $v;
}
}
// Combine unique entries into a single array
// and non-unique entries into a single element
foreach($arr as $key=>$val){
foreach($val as $k=>$v){
$field = array_unique($v);
if(count($field) == 1){
$field = array_values($field);
$field = $field[0];
$arr[$key][$k] = $field;
} else {
$arr[$key][$k] = $field;
}
}
}
return $arr;
}
For example, in the sample array for this question, running multiarray_merge($mysample, 'name') returns
array(
'Pepsi' => array(
'name' => 'Pepsi',
'store' => 'Over here', // String: Not an array since values are not unique
'number' => array('1234567', '5556734') // Array: Saved as array since values are unique
)
);

Read nested array dynamicly in php

I need to read nested arrays without knowing how the array will look.
For example;
$data = array(
'Data1_lvl1' => array(
'Data1_lvl2' => "value",
'Data2_lvl2' => array(
'Data1_lvl3' => "value"
)
),
'Data2_lvl1' => 'value'
);
Needs to be formatted to strings like:
Data1_lvl1/Data1_lvl2/
Data1_lvl1/Data2_lvl2/Data1_lvl3/
Data2_lvl1/
But the array can be of any size with any number of nested arrays inside it.
$data = array(
'Data1_lvl1' => array(
'Data1_lvl2' => "value",
'Data2_lvl2' => array(
'Data1_lvl3' => "value"
)
),
'Data2_lvl1' => 'value'
);
function printArray($array)
{
foreach ($array as $key=>$value)
{
echo $key.'/';
if (is_array($value))
{
printArray($value);
} else {
echo '<br>';
}
}
}
printArray($data);
If you want to output only the name of array elements then this recursive function will do the trick.
Your data:
$data = array(
'Data1_lvl1' => array(
'Data1_lvl2' => "value",
'Data2_lvl2' => array(
'Data1_lvl3' => "value"
)
),
'Data2_lvl1' => 'value'
);
Function:
function array2str($array, $str) {
foreach($array as $key => $val) {
if (is_array($val) ) {
$str .= $key . '/';
array2str($val, $str);
}
}
echo $str.'<br />';
return $str;
}
array2str($data);
As you can see the script does ECHO in itself with <br /> to break the line when viewing results in a browser.
One way would to walk recursively through array with function similar to this:
<?php
function f($d, $str = '') {
foreach ($d as $key => $val) {
if (is_array($val)) f($val, $str . '/' . $key); // If this element is array parse next level
else print_r($str . '/' . $key . '/'); // Output current string or do what you need to do with it..
}
}
$data = array(
'Data1_lvl1' => array(
'Data1_lvl2' => "value",
'Data2_lvl2' => array(
'Data1_lvl3' => "value"
)
),
'Data2_lvl1' => 'value'
);
f($data);
with that function:
<?php
function print_tree ($data, $prefix = '', &$index = 1) {
foreach($data as $key => $datum) {
echo $index++ . '. ' . ($new_prefix = $prefix . $key . '/') . PHP_EOL;
if (is_array($datum)) {
print_tree ($datum, $new_prefix, $index);
}
}
}
I get
Data1_lvl1/
Data1_lvl1/Data1_lvl2/
Data1_lvl1/Data2_lvl2/
Data1_lvl1/Data2_lvl2/Data1_lvl3/
Data2_lvl1/
