I have an associative array with strings as keys and I want to list all the keys and corresponding values in the order in which it was input. For example:
$arr=array();
$arr['tree']='leaves';
$arr['fruits']='seed';
and output should be like :
keys : tree, fruits
values : leaves,seed

If you're running a version of PHP that supports array dereferencing:
$key = array_keys($arr)[1];
else
$keys = array_keys($arr);
$key = $keys[1];

make it associative array you can get both keys and values
$arr=array('tree'=>'leaves','fruits'=>'seeds');
foreach($arr as $key=>$value)
{
echo $key."====>".$value;
}

Trying to understand how I can take multi-line textbox data and then utilise it using PHP.
Within the textbox I want users to be able to write down the format "Website,URL" per line and then generate as a link.
A user would post multiple lines of text:
E.g
Microsoft,https://microsoft.com
Stackoverflow,https://stackoverflow.com
I understand that I would need to use the php explode to break down the line into an array but how can I seperate the data from within that array and then utilise each point of data in a list format? I've confused myself writing this, hoping someone can help!
Given this :
Microsoft,https://microsoft.com Stackoverflow,https://stackoverflow.com
Expected to got this :
array(
'Microsoft' => 'https://microsoft.com',
'Stackoverflow' => 'https://stackoverflow.com'
)
Code
$data = "Microsoft,https://microsoft.com
Stackoverflow,https://stackoverflow.com";
$result = array();
foreach(explode(' ', $data) as $values){
$key_value = explode(",", $values);
if (isset($key_value[0]) && isset($key_value[1]))
$result[$key_value[0]] = $key_value[1]; // Construct array with meaningful key
}
var_dump($result);
Result
array(2) { ["Microsoft"]=> string(21) "https://microsoft.com" [" Stackoverflow"]=> string(25) "https://stackoverflow.com" }

I am trying to convert string to an array format in my code below. I tried to use explode but it returns my results as
In my code i have
File.php
$dial_deustche_no = $payloadArray[1];
dial_deustche_no = 49744990,49010101 //result
$numbers = json_encode([0 => $dial_deustche_no]);
$numbers =. ["49744990,49010101"] //result
When i use explode results looks like
explode(',', $numbers);
//results
array (
0 => '["49744990',
1 => '49010101"]',
)
This is how i want my results to look like
$numbers = ['49744990','49010101']
PS: Beginner in laravel PHP
Explode it before doing the json_encode
$numbers = explode(',', $payloadArray[1]);

I have written some php code, trying what is to assign a string (tag_of_organization) to a variable and then latter to assign it to array newvar. As i am totally new to php and search a lot for it but cannot find anything, so i am asking it here how to do this. here it is
$organ='tag_of_organization';
$newvar = array();
$newvar["tag_of_organization"] =$organ;
Try with:
$newvar[$organ] = $organ;
You are already correct. put print_r to test print your array
$organ='tag_of_organization';
$newvar = array();
$newvar["tag_of_organization"] =$organ;
print_r($newvar);
Output
Array ( [tag_of_organization] => tag_of_organization )
Update
you want dynamic result
$organ='tag_of_organization';
$newvar = array();
$newvar[$organ] =$organ;
print_r($newvar);
Output
Array ( [tag_of_organization] => tag_of_organization )

Ok as per your suggestion I updated... By default Laravel returns JSON... I have set it to return an array but I am still getting the same row duplicated using:
$limits = array();
foreach($pieces as $coverage_limit){
$limits[] = coveragelimit::index($coverage_limit);
}
return json_encode($limits);
}
You're just overwriting $limits inside that foreach() loop. Perhaps you mean something more like
foreach($pieces as $coverage_limit){
$limits[] = coveragelimit::index($coverage_limit);
^^--- array push?
}
As well, you don't "implement" JSON instead of arrays. You work with NATIVE data structures, then encode that structure into JSON. JSON's a transport format, it's not something you should ever deal with natively.
the $limits array will hold the last value what coveragelimit::index() returns over the iterate, I would suggest a check on coveragelimit::index() return value if it falls with "Marc B"'s answer.
EDIT:
foreach($pieces as $key=>$coverage_limit) {
$limits[$key] = coveragelimit::index($coverage_limit);
}
or
foreach($pieces as $coverage_limit) {
array_push($limits, coveragelimit::index($coverage_limit));
}
both should returns the same as Marc B's answer

I am trying to get strings from a long array value.
for example
$array[1]='this is a good day. The number:1, class:math';
$array[2]='this is a bad day. The number:2, class:english';
$array[3]='this is a fine day. The number:3, class:physics';
I want to get the number:1 or class:math strings out of the array.
I tried
echo array_search('number:1',$array);
but it gave me nothing. I was wondering if there are better ways to do this. Thanks a lot!
I guess you're searching for something like the following. Searching for a needle inside of values of arrays.
<?php
function array_search_inline($needle, $haystack) {
foreach ($haystack as $key => $value) {
if (strpos($value, $needle) !== false) {
return $key;
}
}
return false;
}
?>
Note: array_search simply compares the array's values and does not search inside of them.
