Barand Posted August 23, 2015 Share Posted August 23, 2015 is this what you had in mind? $prevkey = ''; foreach ($flavors as $k1 => $arr) { foreach ($arr as $k2 => $v ) { if ($v=='') { if (isset($flavors[$prevkey][$k2])) { $flavors[$k1][$k2] = $flavors[$prevkey][$k2]; } } $prevkey = $k1; } } echo '<pre>',print_r($flavors, true),'</pre>'; gives Array ( [Japanese] => Array ( [hot] => wasabi [salty] => soy sauce ) [Chinese] => Array ( [hot] => wasabi [pepper-salty] => prickly ash ) [indian] => Array ( [hot] => wasabi [pepper-salty] => prickly ash ) [mexican] => Array ( [hot] => soanzo [salty] => soy sauce ) [russian] => Array ( [hot] => soanzo [pepper-salty] => prickly ash ) [ganda] => Array ( [hot] => soanzo [pepper-salty] => prickly ash ) ) Quote Link to comment https://forums.phpfreaks.com/topic/297905-how-to-replace-empty-values-in-an-array/#findComment-1519494 Share on other sites More sharing options...

And the same setting has to be applied to those next to the full japanese array. the final array should be like this.keeping in mind that it can be bigger than this. Array ( [Japanese] => Array ( [hot] => wasabi [salty] => soy sauce [sweety] => soy rdsauce [bitter] => pepper sauce ) [Chinese] => Array ( [hot] => wasabi [salty] => soy sauce [sweety] => soy rdsauce_one [bitter] => pepper sauce3 ) [indian] => Array ( [hot] => wasabi [salty] => soy sauce [sweety] => soy rdsauce [bitter] => pepper sauce4 ) [mexican] => Array ( [hot] => soanzo [salty] => soy sauce1 [sweety] => soy sauceeur [bitter] => pepper sauce_sausage ) [russian] => Array ( [hot] => soanzo [salty] => soy sauce1 [sweety] => soy sauceeur [bitter] => pepper sauce_pork ) [ganda] => Array ( [hot] => soanzo [salty] => soy sauce1 [sweety] => soy sauce_beef [bitter] => luwombo_chicken ) ) Quote Link to comment https://forums.phpfreaks.com/topic/297905-how-to-replace-empty-values-in-an-array/#findComment-1519564 Share on other sites More sharing options...
Solution Barand Posted August 24, 2015 Solution Share Posted August 24, 2015 $prevkey = ''; foreach ($flavors as $k1 => $arr) { foreach ($arr as $k2 => $v ) { if ($v=='') { if (isset($flavors[$prevkey][$k2])) { $flavors[$k1][$k2] = $flavors[$prevkey][$k2]; } } } $prevkey = $k1; } echo '<pre>',print_r($flavors, true),'</pre>'; Sorry, I had $prevkey = $k1; in the wrong place.
