I'm doing some work with a Google Analytics class. I get output as below:
Array
(
[20090401] => Array
(
[ga:pageviews] => 5000
[ga:visits] => 2500
)
[20090402] => Array
(
[ga:pageviews] => 5000
[ga:visits] => 2500
)
etc. How do I get the data to display in a table with the first column showing the date? ie the key for each array element.
like this:
20090401-----5000-----2500
Try this:
<?php
foreach ($report as $date=>$item) {
print($date.'-----'.$item['ga:pageviews'].'-----'.$item['ga:visits']);
}
?>
The piece you were missing was assigning the optional variable for the key in your foreach.
I'm not quite sure what you're asking but maybe this would help...
<?php
foreach($array as $key => $value)
{
echo $key . " => " . $value;
}
?>
Untested, but here's the idea...
foreach ( $report as $item => $data ) {
echo implode( '-----', array( $item, $data['ga:pageviews'], $data['ga:visits'] ) );
}
foreach($array AS $date => $data){
echo '
<tr>
<td>'.$date.'</td>
<td>'.$data['ga:pageviews'].'</td>
<td>'.$data['ga:visits'].'</td>
</tr>';
}
Check the php documentation about the foreach construct if you did not know about it.
The PHP function array_keys might help you out too: http://us.php.net/manual/en/function.array-keys.php

I've tried to display this information tons of times, i've looked all over stackoverflow and just can't find an answer, this isn't a duplicate question, none of the solutions on here work. I've a json array which is stored as a string in a database, when it's taken from the database it's put into an array using json_decode and looks like this
Array
(
[0] => Array
(
[0] => Array
(
)
[1] => Array
(
[CanViewAdminCP] => Array
(
[Type] => System
[Description] => Grants user access to view specific page
[Colour] => blue
)
)
)
)
However, when i try to loop through this, it just returns nothing, I've tried looping using keys, i've tried foreach loops, nothing is returning the values, I'm looking to get the Array key so "CanViewAdminCP" and then the values inside that key such as "Type" and "Description".
Please can anybody help? thankyou.
Use a recursive function to search for the target key CanViewAdminCP recursively, as follows:
function find_value_by_key($haystack, $target_key)
{
$return = false;
foreach ($haystack as $key => $value)
{
if ($key === $target_key) {
return $value;
}
if (is_array($value)) {
$return = find_value_by_key($value, $target_key);
}
}
return $return;
}
Example:
print_r(find_value_by_key($data, 'CanViewAdminCP'));
Array
(
[Type] => System
[Description] => Grants user access to view specific page
[Colour] => blue
)
Visit this link to test it.
You have a 4 level multidimensional array (an array containing an array containing an array containing an array), so you will need four nested loops if you want to iterate over all keys/values.
This will output "System" directly:
<?php echo $myArray[0][1]['CanViewAdminCP']['Type']; ?>
[0] fetches the first entry of the top level array
[1] fetches the second entry of that array
['CanViewAdminCP'] fetches that keyed value of the third level array
['Type'] then fetches that keyed value of the fourth level array
Try this nested loop to understand how nested arrays work:
foreach($myArray as $k1=>$v1){
echo "Key level 1: ".$k1."\n";
foreach($v1 as $k2=>$v2){
echo "Key level 2: ".$k2."\n";
foreach($v2 as $k3=>$v3){
echo "Key level 3: ".$k3."\n";
}
}
}
Please consider following code which will not continue after finding the first occurrence of the key, unlike in Tommassos answer.
<?php
$yourArray =
array(
array(
array(),
array(
'CanViewAdminCP' => array(
'Type' => 'System',
'Description' => 'Grants user access to view specific page',
'Colour' => 'blue'
)
),
array(),
array(),
array()
)
);
$total_cycles = 0;
$count = 0;
$found = 0;
function searchKeyInMultiArray($array, $key) {
global $count, $found, $total_cycles;
$total_cycles++;
$count++;
if( isset($array[$key]) ) {
$found = $count;
return $array[$key];
} else {
foreach($array as $elem) {
if(is_array($elem))
$return = searchKeyInMultiArray($elem, $key);
if(!is_null($return)) break;
}
}
$count--;
return $return;
}
$myDesiredArray = searchKeyInMultiArray($yourArray, 'CanViewAdminCP');
print_r($myDesiredArray);
echo "<br>found in depth ".$found." and traversed ".$total_cycles." arrays";
?>
Please provide help on how to write array values if I have array like this:
Array (
[937245328] => $0.79
[310776983] => $0.53
[720315389] => $0.39
[310800933] => $0.30
[1011934667] => $0.28
[1576813623] => $0.21
[926978479] => $0.19
[1011934570] => $0.14
[937244096] => $0.14
[310777321] => $0.13
[384801319] => $0.13
[519987816] => $0.12
[992123310] => $0.11
)
I would like to print this array out somelike this:
937245328: $0.79
310776983: $0.53
720315389: $0.39
and so on... Thanks for any help.
if your array is called
$myArray
Then you can print it out as follows:
<?php
foreach ($myArray as $key => $value)
{
echo $key.": ".$value."<br>";
}
?>
Let me know if that worked for you! :)
You can print the array (the key and the value) using foreach loop.
<?php
$dolla = Array (
'937245328' => '$0.79',
'310776983' => '$0.53',
'720315389' => '$0.39'
);
foreach($dolla as $key => $value) {
echo $key.": ".$value."<br>";
}
?>
I'm using PDO::FETCH_ASSOC and i'm trying to get data in mysql. This is my sql data:
Array
(
[lessons_media_id] => 1
[lessons_id] => 1
[lessons_media_photo] => http://link1
)
Array
(
[lessons_media_id] => 2
[lessons_id] => 1
[lessons_media_photo] => http://link2
)
I use foreach:
<?php
foreach($data as $key => $value){
echo $value["lessons_media_photo"];
}
?>
Outputs:
http://link1 http://link2
I wanna use one by one. How can I do this ?
Examples:
<p>http://link1</p>
<img src="http://link2">
Try This:
<?php
foreach($data as $key => $value){
echo '<p>'.$value["lessons_media_photo"].'</p>';
echo '<img src = '.$value["lessons_media_photo"].'>';
}
?>
I am trying to delete an array whereby one of its values..(time) meet a specific condition. \The code I'm currently working with looks like this:
foreach($_SESSION as $key) {
foreach($key['time'] as $keys=>$value){
if(condition){
unset($key);
}
}
}
The array looks like this.
Array
(
[form1] => Array
(
[hash] => lFfKBKiCTG6vOQDa8c7n
[time] => 1401067044
)
[form5] => Array
(
[hash] => TTmLVODDEkI1NrRnAbfB
[time] => 1401063352
)
[form4] => Array
(
[hash] => XCVOvrGbhuqAZehBmwoD
[time] => 1401063352
)
I tried to adapt solutions from these pages but didn't work.
Remove element in multidimensional array and save
PHP - unset in a multidimensional array
PHP How to Unset Member of Multidimensional Array?
If you want to unset the values inside it, a simple single foreach will suffice. Consider this example:
$values = array(
'form1' => array('hash' => 'lFfKBKiCTG6vOQDa8c7n', 'time' => 1401067044),
'form5' => array('hash' => 'TTmLVODDEkI1NrRnAbfB', 'time' => 1401063352),
'form4' => array('hash' => 'XCVOvrGbhuqAZehBmwoD', 'time' => 1401063352),
);
$needle = 1401067044;
foreach($values as $key => &$value) {
if($value['time'] == $needle) {
// if you want to remove this key pair use this
unset($values[$key]['time']);
// if you just want to remove the value inside it
$value['time'] = null;
// if you want to remove all of this entirely
unset($values[$key]);
}
}
Fiddle
Unsetting in a for loop can lead to issues, its easier and better to use array_filter which is optimized for this kind of problem. Here is how to do it with your example. ideone running code
<?php
$ar = Array(
"form1" => Array
(
"hash" => 'lFfKBKiCTG6vOQDa8c7n',
"time" => '1401067044'
),
"form5" => Array
(
"hash" => 'TTmLVODDEkI1NrRnAbfB',
"time" => '1401063352'
),
"form4" => Array
(
"hash" => 'XCVOvrGbhuqAZehBmwoD',
"time" => '1401063352'
)
);
$condition = '1401067044';
$newArray = array_filter($ar, function($form) use ($condition) {
if (!isset($form['time'])) {
return true;
}
return $form['time'] != $condition;
});
var_export($newArray);
array_filter
Assuming your values are stored in $_SESSION
foreach($_SESSION as $key => $value) {
if(isset($value['time']) && $value['time'] < 1401063352) {
unset($_SESSION[$key]);
}
}
If you are storing your values in $_SESSION you may want to consider storing them in a subfield like $_SESSION['myForms'] so if you need to add other values to your session you can easily access only the values you need.
You need to do
unset($_SESSION[$key])
However as mentioned by Victory, array_filter is probably a better approach to this.
I need some help reading the values from multidimension arrays. The array looks like below.
Array
(
[translations] => Array
(
[0] => Array
(
[translatedText] => fantasma
[detectedSourceLanguage] => en
)
)
)
I tried the following, but kept on getting blanks. Any help be appreciated?
foreach($item as $translations)
{
foreach($row['0'] as $k)
{
echo $k['translatedText'];
echo $k['detectedSourceLanguage'];
}
}
When working with foreach loops, you want to call the array you plan on iterating over with the following syntax:
foreach($array as $variable){ }
Array being the array you plan on going through, and the variable being the variable you are planning to call it as within the foreach.
More information on foreach loops can be found at PHP:foreach
With that said, try the code below:
$data = array(
"translations" => array(
array("translatedText" => "fantasma",
"detectedSourceLanguage" => "en"
)
)
);
echo "<pre>";
echo print_r($data);
echo "</pre>";
foreach($data["translations"] as $translation) {
echo $translation['translatedText'] . "<br />";
echo $translation['detectedSourceLanguage'] . "<br />";
}
//Or, if the $data variable will be holding multiple translation arrays:
foreach($data as $d) {
foreach($d as $translation){
echo $translation['translatedText'];
echo $translation['detectedSourceLanguage'];
}
}
Try this:
foreach ($item['translations'] as $translation) {
echo $translation['translatedText'];
echo $translation['detectedSourceLanguage'];
}
See DEMO
Change your code to below :
$test = Array(
"translations" => Array (
"0" => Array (
"translatedText" => "fantasma",
"detectedSourceLanguage" => "en"
)
)
);
foreach ($test as $translations) {
foreach ($translations as $k) {
echo $k["translatedText"];
echo "<br/>";
echo $k["detectedSourceLanguage"];
}
}
This should work.
Follow this for more info about array : http://php.net/manual/en/language.types.array.php
The issue is that you are not defining the $row variable. The good news is that you don't need it.
You can simply do this:
foreach($item as $translations => $values)
{
foreach($values as $k)
{
echo $k['translatedText']."\n";
echo $k['detectedSourceLanguage'];
}
}
