here is my code
echo '<pre>';
print_r($header);
echo '</pre>';
and here is the output
Array
(
[1] => Array
(
[A] => Name
[B] => rollnumber
[C] => class
[D] => marks
)
)
I want to read the all array like I want to display
Name rollnumber class marks in table td using loop any help? thanks
you can try this:
foreach($header as $key => $value){ // start $header array loop
if(is_array($value)){ // check if the $value is another array
foreach($value as $k => $v){ // start $value array loop
echo $v.'<br>'; // output $v 'Name rollnumber class marks'
}
}else{
echo $value.'<br>'; // in your case $value is array but you will be able to use like array(1=>array(), 2=>string) the 2 will be the output without a foreach loop
}
}

I have an array, the output of print_r is:
Array ( [0] => Array ( [ID] => 1 [col1] => 1 ) [1] => Array ( [ID] => 2 [col1] => 2 ) )
Could you help of kind of array it is? So that I could research more about it? What I want is to get ID and col1 values
I've tried to use foreach:
foreach($array_name as $key=>$value){
print "$key holds $value\n";
}
The output I get is 0 holds Array 1 holds Array
And I would simply like to get:
1 1
2 2
It's a multi dimensional array, or an array where each element is another array. So you'll need to loop twice. Try this to look at it:
foreach($array_names as $arr)
{
foreach($arr as $key => $val)
{
print "$key = $val\n";
}
}
Or, to get your just added desired output, do this:
foreach($array_names as $arr)
{
foreach($arr as $key => $val)
{
print "$val ";
}
print "\n";
}
Or this:
foreach($array_names as $arr)
{
print $arr['ID'] . " " . $arr['col1'] . "\n";
}
or a few other ways but you should be getting the picture.
I have a output of print_r below and I want to access all the individual elements value with foreach loop but unfortunately I am unable to do that via foreach. Could anyone please help me with the associate array question.
I can access via this $arr['Level1'][Date] and it returns value as "2015-04-14 07:15".
But how to get all the element values via foreach loop?
Array
(
[Level1] => Array
(
[Date] => 2015-04-14 07:15
[img1] => pic1
[img2] => pic2
[InnerLevel] => Array
(
[0] => value1
[1] => value2
)
)
[Level2] => Array
(
[Date] => 2015-04-15 08:15
[img1] => pic1
[img2] => pic2
[InnerLevel] => Array
(
[0] => value3
[1] => value4
)
)
)
<?php
foreach ($myarray as $level => $itemArr) {
if(is_array($itemArr)) {
foreach ($itemArr as $levelArr) {
if(is_array($levelArr)) {
foreach ($levelArr as $key => $interlevelValue) {
echo $interlevelValue;
}
} else {
echo $levelArr;
}
}
} else {
echo $itemArr;
}
}
?>
foreach ($myarray as $item) {
echo $item['Date'] . "\n";
}
The fact that the array is associative or not doesn't change anything.
$item is successively a copy of $myarray['Level1'] then $myarray['Level2'] (etc. if more) in the foreach loop.
It depends on index depth.
To extract simple associative arrays like:
$mainarray['Name']='Value';
Use:
foreach ($mainarray as $aname=>$avalue)
{
echo $aname." in ".$mainarray." = ".$avalue." <br>";
}
To extract deeper associative arrays like:
$mainarray['Child']['Name']='Value';
Use:
foreach ($mainarray as $aname=>$asubarray)
{
echo "In ".$aname." from ".$mainarray."...<br>";
foreach ($asubarray as $asubname=>$asubvalue){
echo $asubname." = ".$avalue." <br>";
}
echo "<br>";
}
This:
<br>
represents new line. If you're running the code from a command line or you just want text only output, then use this for a new line:
\n
Actually there is another way of doing this in php.
"Iterating over Multidimensional arrays is easy with Spl Iterators :
$iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($array));
foreach($iterator as $key=>$value) {
echo $key.' -- '.$value.'<br />';
}
This will iterate through all possible iterable objects.

I am trying to add elements in Array of Array as
$categoryTreeStructure[$grantCategoryName][$parentCategoryName][$subCategoryText]['text'] =$subCategoryText;
// GET CHILD CATEGORY URL
$categoryTreeStructure[$grantCategoryName][$parentCategoryName][$subCategoryText]['url'] = $childPageLink;
I tried to loop through each category as
foreach($categoryTreeStructure as $categoryName => $subCategories ){
echo $categoryName."<br>";
}
I am getting blank in $categoryName.
I need to loop through each category how can I do this?
foreach($categoryTreeStructure as $categoryName => $subCategories ){
foreach($subCategories as $key => $val){
foreach($val as $subkey => $subval){
echo $subval['text'] . "<br>";
echo $subval['url'];
}
}
}
The only way I can see it working is if you use nested loops
Your problem is the second dimension of your array isn't target. You array look like so :
Array
(
[] => Array
(
[] => Array
(
[foo] => Array
(
[text] => foo
[url] => Bar
)
)
)
)
If you want to accept you data you will nice a foreach like this :
foreach($categoryTreeStructure[$parentCategoryName] as $categoryName ){
print_r($categoryName);
}
This will output :
Array
(
[foo] => Array
(
[text] => foo
[url] => Bar
)
)
But in your exemple you wanted the direct text so :
foreach($categoryTreeStructure[$grantCategoryName][$parentCategoryName][$subCategoryText] as $categoryName ){
echo $categoryName;
}
This will output :
foo
Bar
This is the answer for your exemple as your exemple only seen to loop in the last array but if you have multiple subCategoryText as expected you will need to have nested loop like #Rossco pointed out :
foreach($categoryTreeStructure as $categoryName => $subCategories ){
foreach($subCategories as $key => $val){
foreach($val as $subkey => $subval){
echo $subval['text'] . "<br>";
echo $subval['url'];
}
}
}
I'm trying to print array. All code working fine.But at last I'm getting `ArrayArray'. Can any one solve this problem. many many thanks
here is my array
Array
(
[Post1] => Array
(
[id] => 1
[title] => hi
)
[Post2] => Array
(
[0] => Array
(
[id] => 1
)
)
[Post3] => Array
(
[0] => Array
(
[id] => 1
)
)
)
Here is my PHP Code
foreach($post as $key => $value) {
foreach($value as $print => $key) {
echo "<br>".$key;
}
}
here is output
ID
Array
Array
Try this:
foreach($post as $key => $value) {
foreach($value as $print => $key) {
if (is_array($key)){
foreach($key as $print2 => $key2) {
echo "<br>".$key2;
}
}else{
echo "<br>".$key;
}
}
}
The to string method of an array is to return "Array".
It sounds like you want to view the array for debugging purposes. var_dump() is your friend :)
you are trying to print an array, resulting in Array.
If you want to print an array use print_r
I think the trouble for you is that you have $key in the outer loop and $key in the inner loop so its really confusing which $key you are talking about for starters.
You just want the stuff printed out to debug?
echo "<pre>" . print_r( $post , true ) . "</pre>\n";
foreach ($_GET as $field => $label) {
$datarray[]=$_GET[$field];
echo "$_GET[$field]";
echo "<br>";
This is the output I am getting. I see the data is there in datarray but when I echo $_GET[$field] I only get "Array"
But print_r($datarray) prints all the data. Any idea how I pull those values?
OUTPUT:
Array (
[0] => Array (
[0] => Grade1
[1] => ln
[2] => North America
[3] => yuiyyu
[4] => iuy
[5] => uiyui
[6] => yui
[7] => uiy
[8] => 0:0:5
)
)
foreach ($_GET as $key => $value)
{
if(is_array($value))
{
foreach($value as $childKey => $childValue)
{
echo $childKey." ".$childValue; // or assign them to an array
}
}
else
echo $key." ".$value; // or assign them to an array
}
Seems like $_GET[$field] is basically $_GET[0], which is an array:
You'll have to loop through $_GET[$field] with a forloop to get the content to echo out. By the way you can't echo array you'll have to use print_r
something like this:
foreach ($_GET as $field => $label) {
$datarray[]=$_GET[$field];
for($i=0; $i<$_GET[$field]; $i++){
echo $_GET[$field][$i];
}
echo "<br>";
}
EDIT: When I completed your test, here was the final URL:
http://hofstrateach.org/Roberto/process.php?keys=Grade1&keys=Nathan&keys=North%20America&keys=5&keys=3&keys=no&keys=foo&keys=blat&keys=0%3A0%3A24>
This is probably a malformed URL. When you pass duplicate keys in a query, PHP makes them an array. The above URL should probably be something like:
http://hofstrateach.org/Roberto/process.php?grade=Grade1&schoolname=Nathan®ion=North%20America&answer[]=5&answer[]=3&answer[]=no&answer[]=foo&answer[]=blat&time=0%3A0%3A24
This will create individual entries for most of the fields, and make $_GET['answer'] be an array of the answers provided by the user.
Bottom line: fix your Flash file.
