I have a below array in PHP
$arrOrders['remains'] = 'ASC';
$arrOrders['rate'] = 'DESC';
How can I use combine to a string like just with native function?
$str = 'remain ASC, rate DESC';

$a = array(
'remains' => 'ASC',
'rate' => 'DSC'
);
echo implode(', ', array_map(function($v1, $v2) {
return sprintf('%s %s', $v1, $v2);
}, array_keys($a), array_values($a)));
// remains ASC, rate DSC

are you always use all PHP function you know for the every simple operation?

+1 for use of functions, anyone know how would this preform vs the simple foreach HL. posted?

Not really - but I must admit that I like the functional approach on arrays. It's a matter of taste...
Your Common Sense
it's matter of bloating your code, dude. unnecessarily bloating.

Don't worry so much, because I want to have a approach like that... I know if I care about performance I could be consider with just loop. :)

use a foreach and implode()
foreach ($arrOrders as $key => $val) {
$temp[] = "$key $val";
}
$order = implode(',', $temp);

You can do this:
$string = '';
foreach($arrOrders as $key => $value)
$string = $string . "$key $value, ";
$string = rtrim($string, ', '); // cut the last comma at the end of the string
echo $string // remains ASC, rate DESC

I'll +1 it anyway now, as it's the only sensible answer here.

yeah, sense of community, as you said. this very community is a sick one. almost every answer is unusable or propagationg whatever bad practice. that's why I am too strict with votes. it is a custome here to upvote FOR NOTHING, just for a sympathy. Ever complained for the unjust upvote?
Your Common Sense
LOL, so, you have never complained. I thought so. it's only downvotes your concern :)
Your Common Sense
no. as i said already, this site suffer from huge lack of downvotes.
Your Common Sense
that's impossible. most of them do care only of votes, not of knowledge
you are looking for implode, but it dose not include the keys, but the first comment on the page is a function for including keys
/**
* Implode an array with the key and value pair giving
* a glue, a separator between pairs and the array
* to implode.
* @param string $glue The glue between key and value
* @param string $separator Separator between pairs
* @param array $array The array to implode
* @return string The imploded array
*/
function array_implode( $glue, $separator, $array ) {
if ( ! is_array( $array ) ) return $array;
$string = array();
foreach ( $array as $key => $val ) {
if ( is_array( $val ) )
$val = implode( ',', $val );
$string[] = "{$key}{$glue}{$val}";
}
return implode( $separator, $string );
}
$arrOrders = array(
'remains' => 'ASC',
'rate' => 'DSC'
);
$str = array_implode( ' ', ', ', $arrOrders);

do you get an error or something? are you sure you used it correct, it is working fine for me
Your Common Sense
@vietean ever considered possibility to learn from that code, not just copypaste it?
foreachto handle an array?
