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>";
});

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++;
}
After searching for an answer in this forum I found only related questions but under other context that would not apply to my case. Here's my problem:
I have a 3-dim array defined in a function like this:
$m_Array[h][$family][$iterator]
the values for
$family range from 6-10;
$iterator from 0-3 but has duplicates (0,1,2,3,1),
and the $m_Array results in values (25,26,30,31,33).
I am unable to echo the result using those indices to get these results once returned from the function.
NOTE: I was able to echo when I had 2-dim $m_Array[h][$iterator] but could not use it because the last value for the iterator would replace the second in the array.
Since I was able to echo the 2-dim, this is not a question on getting the return from the function or iterate over the indices.
Thanks.
Use print_r($arrayName) to print an array. You cannot echo an Array or Object
as others mentioned, you can use var_dump() or print_r(). If you need to access each item then you're going to need nested loops.
foreach($m_Array as $i => $h)
{
//echo $i, $key for h
foreach($h as $j => $family)
{
//echo $j, key for family
foreach($family as $k => $iterator)
{
echo $iterator;
}
}
}
try this:
$keys = array_keys($h);
for($i = 0; $i < count($h); $i++) {
echo $keys[$i] . "{<br>";
foreach($h[$keys[$i]] as $key => $value) {
echo $key . " : " . $value . "<br>";
}
echo "}<br>";
}
It prints all values and keys
I have this array:
$json = json_decode('
{"entries":[
{"id": "29","name":"John", "age":"36"},
{"id": "30","name":"Jack", "age":"23"}
]}
');
and I am looking for a PHP "for each" loop that would retrieve the key names under entries, i.e.:
id
name
age
How can I do this?
Try it
foreach($json->entries as $row) {
foreach($row as $key => $val) {
echo $key . ': ' . $val;
echo '<br>';
}
}
In the $key you shall get the key names and in the val you shal get the values
You could do something like this:
foreach($json->entries as $record){
echo $record->id;
echo $record->name;
echo $record->age;
}
If you pass true as the value for the second parameter in the json_decode function, you'll be able to use the decoded value as an array.
I was not satisfied with other answers so I add my own. I believe the most general approach is:
$array = get_object_vars($json->entries[0]);
foreach($array as $key => $value) {
echo $key . "<br>";
}
where I used entries[0] because you assume that all the elements of the entries array have the same keys.
Have a look at the official documentation for key: http://php.net/manual/en/function.key.php
You could try getting the properties of the object using get_object_vars:
$keys = array();
foreach($json->entries as $entry)
$keys += array_keys(get_object_vars($entry));
print_r($keys);
foreach($json->entries[0] AS $key => $name) {
echo $key;
}
$column_name =[];
foreach($data as $i){
foreach($i as $key => $i){
array_push($column_name, $key);
}
break;
}
Alternative answer using arrays rather than objects - passing true to json_decode will return an array.
$json = '{"entries":[{"id": "29","name":"John", "age":"36"},{"id": "30","name":"Jack", "age":"23"}]}';
$data = json_decode($json, true);
$entries = $data['entries'];
foreach ($entries as $entry) {
$id = $entry['id'];
$name = $entry['name'];
$age = $entry['age'];
printf('%s (ID %d) is %d years old'.PHP_EOL, $name, $id, $age);
}

How to echo out the values individually of this array?
Array ( [0] => 20120514 [1] => My Event 3 )
so
echo $value[0]; etc
I have this so far:
foreach (json_decode($json_data_string, true) as $item) {
$eventDate = trim($item['date']);
// positive limit
$myarray = (explode(',', $eventDate, 2));
foreach ($myarray as $value) {
echo $value;
}
This echo's out the whole string no as an array. and if i do this?
echo $value[0};
Then I only get 2 characters of it??
The print_r :
Array ( [0] => 20120430 [1] => My Event 1 )
foreach ($array as $key => $val) {
echo $val;
}
Here is a simple routine for an array of primitive elements:
for ($i = 0; $i < count($mySimpleArray); $i++)
{
echo $mySimpleArray[$i] . "\n";
}
you need the set key and value in foreach loop for that:
foreach($item AS $key -> $value) {
echo $value;
}
this should do the trick :)
The problem here is in your explode statement
//$item['date'] presumably = 20120514. Do a print of this
$eventDate = trim($item['date']);
//This explodes on , but there is no , in $eventDate
//You also have a limit of 2 set in the below explode statement
$myarray = (explode(',', $eventDate, 2));
//$myarray is currently = to '20'
foreach ($myarray as $value) {
//Now you are iterating through a string
echo $value;
}
Try changing your initial $item['date'] to be 2012,04,30 if that's what you're trying to do. Otherwise I'm not entirely sure what you're trying to print.
var_dump($value)
it solved my problem, hope yours too.
$arr['thisiskey'] = 1；
Like above,how to get "thisiskey" programmatically?
Use array_keys:
$keys = array_keys($array);
var_dump($keys[0]);
The simplest solution:
key($arr);
key returns current key of the array
Iteratively:
foreach ($array as $key => $value){
print $key . ' = ' . $value .'\n';
}
foreach ($arr as $key => $value) {
echo $key . PHP_EOL;
}
list($key, ) = each($arr);
print $key;
