Given the following array
$locationIcon = array(
'face' => 'FontAwesome',
'code' => '\uf015',
'size' => 75,
'color' => 'gray',
);
which is encoded via json_encode, I would like to have this output:
{
face: 'FontAwesome',
code: '\uf015',
size: 75,
color: 'gray'
}
but instead I get these results:
Version 1
json_encode($array)
=>
"icon":{"face":"FontAwesome","code":"\\uf2bd","size":40,"color":"gray"}
Version 2 as seen here
json_encode($array, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE)
=>
"icon" {"face":"FontAwesome","code":"\\uf2bd","size":40,"color":"gray"} (same)
Version 3 (add an escape char)
$locationIcon = array(
'face' => 'FontAwesome',
'code' => sprintf('%cuf2bd', 27),
'size' => 100,
'color' => 'gray',
);
json_encode($array)
=>
"icon" {"face":"FontAwesome","code":"\u001buf233","size":40,"color":"gray"}
Any ideas what I am doing wrong?
Well, you have written the string "backslash u f zero one five", and JSON-encoding that preserves it exactly with that meaning. There's no sane way around that. Write the actual character you want, not "\uf015". Since this particular character can be slightly awkward to write, write it in some alternative notation, like raw UTF-8 bytes:
$locationIcon = [
'code' => "\xEF\x80\x95", // U+F015
...
];
echo json_encode($locationIcon); // {"code": "\uf015", ...}

So I found an answer which is supposed to work, however it doesn't appear too...
Already accepted answer with the same issue.
I have got the following array called $banners:
[
0 => [
"bannerCustomTemplate" => 0,
"bannerId" => 1,
"bannerType" => 1,
"bannerTitle" => "Merry",
"bannerStrapline" => "Christmas",
"bannerPeriod" => "2018-12-01 to 2018-12-10",
"bannerText" => "Christmas opening hours"
],
1 => [
"bannerCustomTemplate" => 0,
"bannerId" => 7,
"bannerType" => 2,
"bannerTitle" => "Easter",
"bannerStrapline" => "Test",
"bannerPeriod" => "2018-12-04 to 2018-12-12",
"bannerText" => "dsadasdaas"
]
]
The answers I have read suggest $all_banners = call_user_func_array('array_merge', $banners);.
However this is giving me:
[
"bannerCustomTemplate" => 0,
"bannerId" => 7,
"bannerType" => 2,
"bannerTitle" => "Easter",
"bannerStrapline" => "Test",
"bannerPeriod" => "2018-12-04 to 2018-12-12",
"bannerText" => "dsadasdaas"
]
Seems like it's just replacing rather than merging. Anyone got any ideas?
Edit
Just read the following comment
Little note here. The updated variant with unpacking array doesn't work with string keys. But the first one works perfect. Just keep in mind this. – Alliswell
So I have now updated my code with another solutions, with the same results.
Edit 2
Well, merging is merging not replacing. So what I expect is:
[
"bannerCustomTemplate" => [ 0, 0 ],
"bannerId" => [ 1, 7 ],
"bannerType" => [ 1, 2 ],
"bannerTitle" => [ "Merry", "Easter" ]
"bannerStrapline" => [ "Christmas", "Test" ]
"bannerPeriod" => [ "2018-12-01 to 2018-12-10", "2018-12-04 to 2018-12-12" ]
"bannerText" => ["Christmas opening hours", "dsadasdaas" ]
]
If all your arrays are known to contain the same keys in the same order, this is probably easiest:
$data = [
['foo' => 'bar', 'baz' => 42],
['foo' => 'baz', 'baz' => 69]
];
$result = array_combine(array_keys($data[0]), array_map(null, ...$data));
This uses the useful behaviour of array_map with null as the callback to take one element from each input array and return a new combined array.
Im retrieving data from a mysql database like following Array:
$data = [
0 => [
'id' => 1,
'Benutzer' => 'foo',
'Passwort' => '123456',
'Adresse' => [
'Strasse' => 'bla', 'Ort' => 'blubb'
],
'Kommentare' => [
0 => ['Titel' => 'bar', 'Text' => 'This is great dude!'],
1 => ['Titel' => 'baz', 'Text' => 'Wow, awesome!']
]
],
]
Data like this shall be stored in a mongo database and therefore i want to replace the keynames with translated strings that come from a config- or languagefile ('Benutzer' -> 'username').
Do i really have to iterate over the array and replace the keys or is the a better way to achieve that?
If you don't want to iterate over the array then you can change the column name in the query itself using select() function.
Considering your model name is Client then your query will be:
Client::select('Benutzer as username', '...') // you can use `trnas()` function here also
->get()
I'm using an API which gives an example of how they want the data of the POST request I'm about to make to be formatted. This is their example:
un=chris&
key=xxxx&
origin=plot&
platform=lisp&
args=[[0, 1, 2], [3, 4, 5], [1, 2, 3], [6, 6, 5]]&
kwargs={"filename": "plot from api",
"fileopt": "overwrite",
"style": {
"type": "bar"
},
"traces": [1],
"layout": {
"title": "experimental data"
},
"world_readable": true
}
I'm confused about how I should put together this data from existing arrays in PHP. From what I understand the example show an encoded "string" that is just partly encoded? As of now I am putting the string together all by myself through extracting the keys and values from the arrays.
I'm looking for a more neat way of doing this with existing methods?
I believe using http_build_query will solve this for you.
Given the example, here's sample of how to use it:
$args = array(array(0,1,2), array(3,4,5), array(1,2,3), array(6,6,5));
$kwargs = array(
'filename' => 'plot from api',
'fileopt' => 'overwrite'
'style' => array('type' => 'bar'),
'traces' => array(1),
'layout' => array('title' => 'experimental data'),
'word_readable' => true
);
$request = array(
'un' => 'chris',
'key' => 'xxx',
'origin' => 'plot',
'platform' => 'lisp',
'args' => $args,
'kwargs' => $kwargs
);
$queryString = http_build_query($request);
echo $queryString;

Imagine this situation:
$component = array(
'type' => 'chimney',
'material' => 'stone'
);
What i would like to do is to add a key/value pair to this array, if a certain condition is met.
$hasMetrics = true;
$component = array(
'type' => 'chimney',
'material' => 'stone',
'metrics' => ($hasMetrics ? array('width' => 60, 'height' => 2000) : false)
);
While this could be used, it will always cause a key called 'metrics' in my array.
Of course, if i don't want that, i could use array_merge() to merge a second array with the first (the second being either an empty array or the desired key/value pair, depending on the condition).
But what i am longing to find out is if there is any way to define this array like above, while taking care of $hasMetrics, without the use of any other means (such as array_merge()) but purely in the actual (first and only) definition of this array.
Like this: (non-applicable, demonstrative example)
$component = array(
'type' => 'chimney',
'material' => 'stone',
($hasMetrics ? array('metrics' => array(
'width' => 60,
'height' => 2000
)) : false)
);
(This, as i understand it, would generate two keys (type and material and then create one keyless value that is, itself, an array containing a key (metrics) and another array as value.)
Can anyone show me some proper approach? Perhaps there is some kind of PHP function available, with special properties (such as list() which is capable of cross-assignment).
EDIT
Perhaps some more clarification is needed, as many answers point out ways to go such as:
Using a followup assignment to a certain key
Filtering the generated array after defining it
While these are perfectly valid ways to extend the array, but i am explicitly looking for a way to do this in one go within the one array definition.
Not with the array defenition itself. I would add it to the array if necessary:
if($hasMetrics) {
$component['metrics'] = array('width' => 60, 'height' => 2000);
}
$hasMetrics = true;
$component = array(
'type' => 'chimney',
'material' => 'stone',
);
if($hasMetrics){
$component['metrics'] = array('width' => 60, 'height' => 2000);
}
Try
$component = array(
'type' => 'chimney',
'material' => 'stone',
'metrics' => $hasMetrics ? array('width' => 60, 'height' => 2000) : ''
);
And after that
$component = array_filter( $component ); // remove if it has '' value
OR
$component = array(
'type' => 'chimney',
'material' => 'stone',
);
if($hasMetrics) {
$component['metrics'] = array('width' => 60, 'height' => 2000);
}
I ran into an issue with a data feed I need to import where for some reason the feed producer has decided to provide data that should clearly be either INT or FLOAT as strings-- like this:
$CASES_SOLD = "THREE";
$CASES_STOCKED = "FOUR";
Is there a way in PHP to interpret the text string as the actual integer?
EDIT: I should be more clear-- I need to have the $cases_sold etc. as an integer-- so I can then manipulate them as digits, store in database as INT, etc.
Use an associative array, for example:
$map = array("ONE" => 1, "TWO" => 2, "THREE" => 3, "FOUR" => 4);
$CASES_SOLD = $map["THREE"]; // 3
If you are only interested by "converting" one to nine, you may use the following code:
$convert = array('one' => 1,
'two' => 2,
'three' => 3,
'four' => 4,
'five' => 5,
'six' => 6,
'seven' => 7,
'eight' => 8,
'nine' => 9
);
echo $convert[strtolower($CASES_SOLD)]; // will display 3
If you only need the base 10 numerals, just make a map
$numberMap = array(
'ONE' => 1
, 'TWO' => 2
, 'THREE' => 3
// etc..
);
$number = $numberMap[$CASES_SOLD];
// $number == 3'
If you need something more complex, like interpreting Four Thousand Two Hundred Fifty Eight into 4258 then you'll need to roll up your sleeves and look at this related question.
Impress your fellow programmers by handling this in a totally obtuse way:
<?php
$text = 'four';
if(ereg("[[.$text.]]", "0123456789", $m)) {
$value = (int) $m[0];
echo $value;
}
?>
You need a list of numbers in english and then replace to string, but, you should play with 'thousand' and 'million' clause where must check if after string 'thousend-three' and remove integer from string.
You should play with this function and try change if-else and add some functionality for good conversion:
I'm writing now a simple code for basic, but you know others what should change, play!
Look at million, thousand and string AND, it should be change if no in string like '1345'. Than replace with str_replace each of them separaterly and join them to integer.
function conv($string)
{
$conv = array(
'ONE' => 1,
'TWO' => 2,
'THREE' => 3,
'FOUR' => 4,
'FIVE' => 5,
'SIX' => 6,
'SEVEN' => 7,
'EIGHT' => 8,
'NINE' => 9,
'TEN' => 10,
'ELEVEN' => 11,
'TWELVE' => 12,
'THIRTEEN' => 13,
'FOURTEEN' => 14,
'FIFTEEN' => 15,
'SIXTEEN' => 16,
'SEVENTEEN' => 17,
'EIGHTEEN' => 18,
'NINETEEN' => 19,
'TWENTY' => 20,
'THIRTY' => 30,
'FORTY' => 40,
'FIFTY' => 50,
'SIXTY' => 60,
'SEVENTY' => 70,
'EIGTHY' => 80,
'NINETY' => 90,
'HUNDRED' => 00,
'AND' => '',
'THOUSAND' => 000
'MILLION' => 000000,
);
if (stristr('-', $string))
{
$val = explode('-', $string);
#hardcode some programming logic for checkers if thousands, should if trim zero or not, check if another values
foreach ($conv as $conv_k => $conv_v)
{
$string[] = str_replace($conv_k, $conv_v, $string);
}
return join($string);
}
else
{
foreach ($conv as $conv_k => $conv_v)
{
$string[] = str_replace($conv_k, $conv_v, $string);
}
return join($string);
}
}
Basically what you want is to write a parser for the formal grammar that represents written numbers (up to some finite upper bound). Depending on how high you need to go, the parser could be as trivial as
$numbers = ('zero', 'one', 'two', 'three');
$input = 'TWO';
$result = array_search(strtolower($input), $numbers);
...or as involved as a full-blown parser generated by a tool as ANTLR. Since you probably only need to process relatively small numbers, the most practical solution might be to manually hand-code a small parser. You can take a look here for the ready-made grammar and implement it in PHP.
This is similar to Converting words to numbers in PHP
PHP doesn't have built in conversion functionality. You'd have to build your own logic based on switch statements or otherwise.
Or use an existing library like:
