I have data like following
string(133) "lindsey#testmail.com=>5.jpg,rickey#testmail.com=>6.jpg,darnell#testmail.com=>84.jpg,ball#gmail.com =>49.jpg,norton#tesing.com=>68.jpg"
i want to explode email and image separately.
i use explode but it didn't work.
i also try associative array.
here is my code but it didn't work.
foreach ($array as $key => $value ) {
echo $key;
echo "<li><img src=\"".base_url()."images/menters/".$values."\" class=\"img-border\"/><span>icon</span></li>\n";
}
i think it happen additional string(133)
i have no idea how to accomplish this
You can't do that with a single explode, you have to explode the string twice. You can then use an associative array to store values and use them
$array = explode(',' $string);
foreach ($array as $key => $val) {
$exp = explode('=>', $val);
$assoc_array[$key]['mail'] = $exp[0];
$assoc_array[$key]['img'] = $exp[1];
}
foreach ($assoc_array as $val) {
echo 'Mail : ', $val['mail'], '<br>';
echo 'Image : ', $val['img'];
}

I am trying to combine two array elements with the string "OR" and create one string of elements.
The array looks like this:
$myarray = array(2282396,1801345)
This is the code i have used.
$bool = ' OR ';
foreach($myarray as $element){
echo $element .= $bool;
}
I trying to get this output after looping using a foreach loop.
2282396 OR 1801345
However, the output i get looks like this:
2282396 OR 1801345 OR
How do i get rid of the 'OR' after the second element? Thanks in advance
You have to check if you're in the first/last iteration or not.
$first = true;
$bool = ' OR ';
foreach ($myarray as $element) {
if (!$first) {
echo $bool;
}
echo $element;
$first = false;
}
If your array is indexed by numeric indexes 0-x, you an use
$bool = ' OR ';
foreach ($myarray as $key => $element) {
if ($key > 0) {
echo $bool;
}
echo $element;
}
Use implode as:
echo implode(" OR ", $myarray);

Live example: 3v4l
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.
I have the following code of which I want to echo array elements separated by commas. The code outputs the disered list, but without commas. What am I missing?
<?php
$array = get_field('casts');
$elements = $array;
foreach($array as $key => $value) {
echo implode(', ', $value)};
?>
EDIT 1: where $elements are nested arrays.
EDIT 2: Working snippet:
<?php
$array = get_field('casts');
$new_array = array();
foreach($array as $sub_array) {
foreach($sub_array as $value) {
array_push($new_array, $value);
}
}
echo implode(", ", $new_array);
?>
Why are you assigning $elements = $array; and then never using $elements?
Also you don't need to loop (foreach) to implode an array.
Try this:
<?php
$array = get_field('casts');
$new_array = array();
foreach($array as $sub_array) {
foreach($sub_array as $value) {
// this array_push() function adds $value to the end of $new_array.
array_push($new_array, $value);
}
}
echo implode(", ", $new_array);
?>
Here is the documentation on implode()
You can play around and test the above code here.
Also next time, add the tag php, otherwise our codes won't get color syntax.
Is there a way to traverse an array such as $_POST to see the field names and not just the values. To see the values I do something like this.
foreach ($_POST as $value){
echo $value;
}
This will show me the values - but I would like to also display the names in that array. If my $_POST value was something like $_POST['something'] and it stored 55; I want to output "something".
I have a few select fields that I need this for.
You mean like this?
foreach ( $_POST as $key => $value )
{
echo "$key : $value <br>";
}
you can also use array_keys if you just want an array of the keys to iterate over.
You can also use array_walk if you want to use a callback to iterate:
function test_walk( &$value, $key )
{
...do stuff...
}
array_walk( $arr, 'test_walk' );
foreach ($_POST as $key => $value) {
echo $key; // Field name
}
Or use array_keys to fetch all the keys from an array.
foreach ($_POST as $key => $value){
echo $key.': '.$value.'<br />';
}
If you just want the keys:
foreach (array_keys($_POST) as $key)
{
echo $key;
}
Or...
foreach ($_POST as $key => $value)
{
echo $key;
}
If you want both keys and values:
foreach ($_POST as $key => $value)
{
echo $key, ': ', $value;
}
For just the keys:
$array = array_keys($_POST);
Output them with:
var_dump($array);
-or-
print_r($array);
