问题 If I am working with an associate array like such: Array ( [Username] => user [Email] => email ) and I want to add an element to the end, I would think to do: array_push($array, array('Password' => 'pass')); However, this leaves me with: Array ( [Username] => user [Email] => email Array ( [Password] => pass ) ) How can this be avoided so I end up with: Array ( [Username] => user [Email] => email [Password] => pass ) Much appreciated! 回答1: You are using an associative array so you just set the

Associative array to Json [closed]

由 烈酒焚心 提交于 2019-12-04 06:27:58
I would like to be able to generate a json output in the following format: {"a":{"ax":1,"abx":2},"b":{"bax":1,"bbx":2},"c":3,"d":4,"e":5} Although I have found that the respective code is this: $arr = array('a' => array('ax' => 1, 'abx' => 2), 'b' => array('bax' => 1, 'bbx' => 2), 'c' => 3, 'd' => 4, 'e' => 5); , I'm struggling to generate this output by using data from an sql query.

由 馋奶兔 提交于 2019-11-30 05:38:31
I am using the following loop to add items to an an array of mine called $liste. I would like to know if it is possible somehow not to add $value to the $liste array if the value is already in the array? Hope I am clear. Thank you in advance. $liste = array(); foreach($something as $value){ array_push($liste, $value); } You check if it's there, using in_array , before pushing. foreach($something as $value){ if(!in_array($value, $liste, true)){ array_push($liste, $value); } } The ,true enables "strict checking".
