I would need to combine two different fields.
In the first field I generate days of the month. I want to list all days of the month.
I would like to add a second field to them, where there are items for each day. But, for example, there are no items on weekends or on other days. Ie. that field two will always have fewer items.
The second field is tightened from the DB.
I would need to do a JOIN like in MySQL for the first field.
It occurred to me that in MySQL it would be possible to make a temporary table with a given month and link it here, but I don't think it's right.
$arrayDate = [0 => '20210401',1 => '20210402',2 => '20210403',3 => '20210404',4 => '20210405',5 => '20210406',6 => '20210407',7 => '20210408',8 => '20210409',9 => '20210410',10 => '20210411',11 => '20210412',12 => '20210413',13 => '20210414',14 => '20210415',15 => '20210416',16 => '20210417',17 => '20210418',18 => '20210419',19 => '20210420',20 => '20210421',21 => '20210422',22 => '20210423',23 => '20210424',24 => '20210425',25 => '20210426',26 => '20210427',27 => '20210428',28 => '20210429',29 => '20210430'];
$arrayItem[35] = ['id' => 35, 'date' => '20210401', 'item' => 'aaaa'];
$arrayItem[36] = ['id' => 36, 'date' => '20210402', 'item' => 'bbbb'];
$arrayItem[37] = ['id' => 36, 'date' => '20210430', 'item' => 'cccc'];
// i need output
20210401 - aaaa
20210402 - bbbb
20210403 - empty
20210404 - empty
...
20210430 - cccc
EDIT: I use nested loops, but I still can't get the right output
foreach ($arrayDate as $date) {
foreach ($arrayItem as $item) {
if ($date == $item['date']) {
bdump($item['date']);
} else {
bdump($date);
}
}
}
bdump($item['date']) = '20210401', '20210402', '20210430'
bdump($date) = '20210401', '20210401', '20210402', '20210402', '20210403', '20210403', '20210403', '20210404', '20210404', '20210404', '20210405', '20210405', '20210405' ....
With array_column you create a array from $arrayItem with date as key.
$dateItem is an array like
array (
20210401 => "aaaa",
20210402 => "bbbb",
20210430 => "cccc",
)
The output you can do with a simple foreach.
$dateItem = array_column($arrayItem,'item','date');
foreach($arrayDate as $date){
echo $date.' '.($dateItem[$date] ?? 'empty')."<br>\n";
}
Note:
With
array_column($arrayItem,null,'date')
you get a two-dimensional array with a date as a key that can be used.
array (
20210401 =>
array (
'id' => 35,
'date' => "20210401",
'item' => "aaaa",
),
20210402 =>
array (
'id' => 36,
'date' => "20210402",
'item' => "bbbb",
),
20210430 =>
array (
'id' => 36,
'date' => "20210430",
'item' => "cccc",
),
)
I have a multidimensional array as follows, which is a PHP array of shoe sizes and their conversions...
$size_array = array(
"M"=>array(
'6'=> array('uk'=>'6','eu'=>'39.5','us'=>'7'),
'6H'=> array('uk'=>'6.5','eu'=>'40','us'=>'7.5'),
'7'=> array('uk'=>'7','eu'=>'40.5','us'=>'8'),
'7H'=> array('uk'=>'7.5','eu'=>'41','us'=>'8.5'),
'8'=> array('uk'=>'8','eu'=>'42','us'=>'9'),
'8H'=> array('uk'=>'8.5','eu'=>'42.5','us'=>'9.5'),
'9'=> array('uk'=>'9','eu'=>'43','us'=>'10'),
'9H'=> array('uk'=>'9.5','eu'=>'44','us'=>'10.5'),
'10'=> array('uk'=>'10','eu'=>'44.5','us'=>'11'),
'10H'=> array('uk'=>'10.5','eu'=>'45','us'=>'11.5'),
'11'=> array('uk'=>'11','eu'=>'46','us'=>'12'),
'11H'=> array('uk'=>'11.5','eu'=>'46.5','us'=>'12.5'),
'12'=> array('uk'=>'12','eu'=>'47','us'=>'13'),
'12H'=> array('uk'=>'12.5','eu'=>'48','us'=>'13.5'),
'13'=> array('uk'=>'13','eu'=>'48.5','us'=>'14')
),
"F"=>array(
'3'=> array('uk'=>'3','eu'=>'35.5','us'=>'5'),
'3H'=> array('uk'=>'3.5','eu'=>'36','us'=>'5.5'),
'4'=> array('uk'=>'4','eu'=>'37','us'=>'6'),
'4H'=> array('uk'=>'4.5','eu'=>'37.5','us'=>'6.5'),
'5'=> array('uk'=>'5','eu'=>'38','us'=>'7'),
'5H'=> array('uk'=>'5.5','eu'=>'38.5','us'=>'7.5'),
'6'=> array('uk'=>'6','eu'=>'39','us'=>'8'),
'6H'=> array('uk'=>'6.5','eu'=>'39.5','us'=>'8.5'),
'7'=> array('uk'=>'7','eu'=>'40','us'=>'9'),
'7H'=> array('uk'=>'7.5','eu'=>'41','us'=>'9.5'),
'8'=> array('uk'=>'8','eu'=>'41.5','us'=>'10'),
'8H'=> array('uk'=>'8.5','eu'=>'42.5','us'=>'10.5'),
'9'=> array('uk'=>'9','eu'=>'43','us'=>'11'),
'9H'=> array('uk'=>'9.5','eu'=>'43.5','us'=>'11.5'),
'10'=> array('uk'=>'10','eu'=>'44','us'=>'12')
)
);
The array is part of a function that returns the conversions based on a supplied size and gender (i.e. SizeConvert('M','6') returns Array ([uk] => 6, [eu] => 39.5,[us] => 7)).
I want to extend the function to allow the passing of a value which will return the array results with any .5 values replaced with ½ (or ½) (i.e. SizeConvert('M','6','Y') returns Array ([uk] => 6, [eu] => 39½,[us] => 7))
How do I make str_replace (or a more appropriate command) iterate over the array and replace the values?
I've tried something like str_replace(".5", "½", $size_array) but I guess that's not working as it's only looking at the initial array, not the sub-arrays.
You are trying to apply this to a multidimensional array without real reason. If you have your SizeConvert function ready and returning a one dimensional array, simply apply the transformation before returning the value:
function SizeConvert(/* other parameters */, bool $convertOneHalf) {
$match = ... // your code to find the match
return $convertOneHalf
? str_replace('.5', '½', $match)
: $match;
}
Based on the boolean value of the parameter that dictates whether the conversion should be applied, we either return the modified or the unmodified result through the ternary.
Do not overthink it and use a for loop to loop through all the elements in the array and use an if...else... to check for 0.5
if($array[index]=="0.5") {
$array[index]="½";
} else {
$array[index]=str_replace(".5", "½", $array[index]);
}
I coded up a simple code, it's not exactly the answer to your question but u can use the logic behind it. The code below will change all the 0.5 in the array to 1⁄2 but since u already acquire the data, there is no need to have so much nested-loop, just 1 level of the loop to loop through all ur elements in your array is enough.
<?php
$size_array = array(
"M" => array(
'6' => array(
'uk' => '6',
'eu' => '39.5',
'us' => '7'
) ,
'6H' => array(
'uk' => '6.5',
'eu' => '40',
'us' => '7.5'
) ,
'7' => array(
'uk' => '7',
'eu' => '40.5',
'us' => '8'
)
) ,
"F" => array(
'3' => array(
'uk' => '3',
'eu' => '35.5',
'us' => '5'
) ,
'3H' => array(
'uk' => '3.5',
'eu' => '36',
'us' => '5.5'
) ,
'4' => array(
'uk' => '4',
'eu' => '37',
'us' => '6'
)
)
);
foreach ($size_array as $firstLevel)
{
foreach ($firstLevel as $secondLevel)
{
foreach ($secondLevelas $values)
{
if ($values== "0.5")
{
echo $values= "½";
}
else
{
echo $values= str_replace(".5", "½", $values);
}
}
}
}
?>
in this array, I want to find word "in" from value and make new array from that songs including number (key) songs from album.
$londonCalling = array(
'song-01' => 'London Calling',
'song-02' => 'Brand New Cadillac',
'song-03' => 'Jimmy Jazz',
'song-04' => 'Hateful',
'song-05' => 'Rudie Cant Fail',
'song-06' => 'Spanish Bombs',
'song-07' => 'The Right Profile',
'song-08' => 'Lost in the Supermarket',
'song-09' => 'Clampdown',
'song-10' => 'The Guns of Brixton',
'song-11' => 'Wrong Em Boyo',
'song-12' => 'Death or Glory',
'song-13' => 'Koka Kola',
'song-14' => 'The Card Cheat',
'song-15' => 'Lovers Rock',
'song-16' => 'Four Horsemen',
'song-17' => 'Im Not Down',
'song-18' => 'Revolution Rock',
'song-19' => 'Train in Vain');
This can be done with preg_grep oneliner:
print_r(preg_grep('/in/', $londonCalling));
alternatively array_filter
$res = array_filter($londonCalling , function($e){
return strpos($e, 'in') !== false;
});
print_r([$res]);
Here is the query string.
$query = "SELECT t.id, t.assignee, t.owner,
d.code, d.status, d.target_completion_date,
d.target_extension_date, d.submission_date, d.approval_date,
d.revision_start_date, d.revision_completion_date, d.message,
ty.name, f.orig_name, f.new_name,
b.payment_date, b.discount, b.total_cost, b.amount_payed, b.edit_level,
b.billing_type, b.pages, b.words

INNER JOIN details d ON t.detail_id = d.id
INNER JOIN billing b ON t.billing_id = b.id
INNER JOIN TYPE ty ON d.document_type_id = ty.id
INNER JOIN files f ON t.file_id = f.id
WHERE t.assignee = 'argie1234'";
And this is the array i would like the query result to turn into.

How can i create the above array? I sure know how to define multi dimensional array, regretfully though i am having difficulty creating this complex array dynamically. As a beginner i don't even know where to begin.
Here is an example that might help you out. Try starting with simple multi dimensional arrays, once you get a hold of it, you can move onto building complex ones. You will then find that the array you want to build is not really difficult than you initially thought it to be.
$mycomplexarray = array('key1' => array('val1', 'val2'),
'key2' => array('val3', 'val4' => array('val5', 'val6')
)
);
You could create the array just as you have here. I'm not gonna write the whole thing out, but something like this...
$result = $mysqli->query($query); // however you query the db is up to you.
$row = $result->fetch_assoc(); //same as query use your prefered method to fetch
$user = array('allTask'=>array(array('taskid' => $row['id'],
'assignee'=>$row['assignee'],
'owner'=>$row['owner'],
'details' => array( 'code' => $row['code'],
'status'=>$row['status'],
...etc, Hope this makes sense for you.
Set up a structure array first that defines which columns will be stored in a sub array like
$struc=array('Id'->0, 'assignee'->0, 'owner'->0,
'code'->'detail', 'status'->'detail', 'target_completion_date'->'detail',
'target_extension_date'->'detail', 'submission_date'->'detail', 'approval_date'->'detail',
'revision_start_date'->'detail', 'revision_completion_date'->'detail', 'message'->'detail',
'name'->'file', 'orig_name'->'file', 'new_name'->'file',
'payment_date'->'billing', 'discount'->'billing', 'total_cost'->'billing', 'amount_payed'->'billing', 'edit_level'->'billing', 'billing_type'->'billing', 'words');
In your while ($a=mysqli_fetch_assoc($res)) loop you can now use this structure to decide whether you want to store an element directly in your target array or whether you want to place it in the subarray named in this structure array. Like
$res=mysqli_query($con,$sql);
$arr=array();
while($a=mysqli_fetch_assoc($res)) {
// within result loop: $a is result from mysqli_fetch_assoc()
$ta=array(); // temp array ...
foreach ($a as $k => $v){
if ($struc[$k]) $ta[struc[$k]][$k]=$v;
else $ta[$k]=$v;
}
$arr[]=$ta; // add to target array
}
This is the complete code, no more is needed. It was typed up on my iPod, so it is NOT tested yet.
The generated array should be equivalent to your $user['allTask'] array.
I have this array
$arr = array(
'one' => array(
'slidertitle' => 'lorem ipsum',
'sliderlocation' => 'http://localhost/images/1.jpg',
'sliderdescription' => 'this is a good lorem ipsum image',
'sliderposition' => 1
),
'two' => array(
'slidertitle' => 'second slider',
'sliderlocation' => 'http://localhost/images/2.jpg',
'sliderdescription' => 'this space was reserved for a link source code here',
'sliderposition' => 2
),
'six' => array(
'slidertitle' => 'sixth slider',
'sliderlocation' => 'http://localhost/images/6.jpg',
'sliderdescription' => 'this is the sixth slider,like,really!',
'sliderposition' => 6
)
);
which i need to look like this
$arr = array(
'two' => array(
'slidertitle' => 'second slider',
'sliderlocation' => 'http://localhost/images/2.jpg',
'sliderdescription' => 'this space was reserved for a link source code here',
'sliderposition' => 2
),
'six' => array(
'slidertitle' => 'sixth slider',
'sliderlocation' => 'http://localhost/images/6.jpg',
'sliderdescription' => 'this is the sixth slider,like,really!',
'sliderposition' => 6
),
'one' => array(
'slidertitle' => 'lorem ipsum',
'sliderlocation' => 'http://localhost/images/1.jpg',
'sliderdescription' => 'this is a good lorem ipsum image',
'sliderposition' => 1
)
);
I am attempting to do that by defining the expected array structure and introducing a dummy array.I then chunk the array and merge each chunk to the array format and i plan to finally unset the dummy and i am left with the array i want and in the order i want.
$arrayFormat = array(
'dummy' => array(
'slidertitle' => 'xxxx',
'sliderlocation' => 'xxxxxxx',
'sliderdescription' => 'xxxxxx',
'sliderposition' => 0
)
);
$arrayLength = count($arr);
$afterChunk = array_chunk($arr,$arrayLength);
$one = $afterChunk[0][0];
$two = $afterChunk[0][1];
$mergedArray = array_merge($arrayFormat,$one);
$secondMergedArray = array_merge($mergedArray,$two);
echo '<pre>';
print_r($secondMergedArray);
echo '</pre>';
The problem is array_chunk() does not include the key of the array so i am getting
Array (
[dummy] => Array
(
[slidertitle] => xxxx
[sliderlocation] => xxxxxxx
[sliderdescription] => xxxxxx
[sliderposition] => 0
)
[slidertitle] => second slider
[sliderlocation] => http://localhost/images/2.jpg
[sliderdescription] => this space was reserved for a link source code here
[sliderposition] => 2 )
when i print_r($secondMergedArray);.is there something that can be done to array_chunk() to include the array key or is there any other array function that can help me get individual array inclusive of the key?.
It's really hard to tell what you're wanting in terms of how to sort the elements. You've not been very clear in the question. There has to be something in the array that you know what order it needs to be.
In the absence of any clues as to what that is, I'm going to assume you want to specify the order of the array keys manually.
So, the current array is array('one'=>... , 'two'=>... , 'six'=>... ) and you want to sort those keys in an order you want to specify manually.
The solution is to use the uksort() function, along with a separate array specifying your sort order:
$arr = ... //input array as specified in the question
$sortOrder = array('two','one','six');
uksort($arr, function ($a, $b) use ($sortOrder) {
$sortMe = array_flip($sortOrder);
if ($sortMe[$a] == $sortMe[$b]) { return 0; }
return ($sortMe[$a] < $sortMe[$b]) ? -1 : 1;
});
print_r($arr);
Outputs your array in 'two','one','six' order. Change the $sortOrder array as required.
Hope that helps.
Note: the syntax I've provided above only works in PHP 5.3 and above. (if you're using an older version, you need to upgrade)
use uksort() for custom order for multidimensional array
