note 124942 added to function.implode

If you want to implode an array as key-value pairs, this method comes in handy. The third parameter is the symbol to be used between key and value. <?php function mapped_implode($glue, $array, $symbol = '=') { return implode($glue, array_map( function($k, $v) use($symbol) { return $k . $symbol . $v; }, array_keys($array), array_values($array) ) ); } $arr = [ 'x'=> 5, 'y'=> 7, 'z'=> 99, 'hello' => 'World', 7 => 'Foo', ]; echo mapped_implode(', ', $arr, ' is '); // output: x is 5, y is 7, z is 99, hello is World, 7 is Foo ?> ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.195 (proxied: 185.22.143.180) ---- Manual Page -- http://php.net/manual/en/function.implode.php Edit -- https://master.php.net/note/edit/124942 Del: integrated -- https://master.php.net/note/delete/124942/integrated Del: useless -- https://master.php.net/note/delete/124942/useless Del: bad code -- https://master.php.net/note/delete/124942/bad+code Del: spam -- https://master.php.net/note/delete/124942/spam Del: non-english -- https://master.php.net/note/delete/124942/non-english Del: in docs -- https://master.php.net/note/delete/124942/in+docs Del: other reasons-- https://master.php.net/note/delete/124942 Reject -- https://master.php.net/note/reject/124942 Search -- https://master.php.net/manage/user-notes.php
