問題描述
限時送ChatGPT賬號..
我正在從數據庫中讀取一些希伯來語文本并嘗試 json_encode 它.如果我 print_r 我得到的結果:
I am reading from database with some text in Hebrew and trying to json_encode it.
if i print_r the results i get:
Array
(
[0] => Array
(
[value] => 88
[text] => ???? ?'
[parent_id] => 1
[level] => 1
)
[1] => Array
(
[value] => 89
[text] => ???? ?'
[parent_id] => 1
[level] => 1
)
[2] => Array
(
[value] => 91
[text] => ???? ?'
[parent_id] => 1
[level] => 1
)
)
雖然 json_encode 顯示:
while the json_encode shows:
[{"value":"88","text":null,"parent_id":"1","level":"1"},{"value":"89","text":null,"parent_id":"1","level":"1"},{"value":"91","text":null,"parent_id":"1","level":"1"}]
我相信這是因為我的數據庫中的文本包含 ( ' ) 標記.嘗試了各種stripslashes或real_escape_string的組合都沒有幫助.
i belive it's because my text from the database contains a ( ' ) mark. tried various combination of stripslashes or real_escape_string none have helped.
推薦答案
json_encode期望數據中的字符串被編碼為 UTF-8.
json_encode expects strings in the data to be encoded as UTF-8.
如果尚未將它們轉換為 UTF-8:
Convert them to UTF-8 if they aren't already:
$results = array_map(function($r) {
$r['text'] = utf8_encode($r['text']);
return $r;
}, $results);
echo json_encode($results);
