用JSON字符串中的空字符串替换制表符和换行符

Question

I have a JSON string which is like this when I log it:

..."items":{"0":"
\t\t\t\t\t"},"buys":{"0":"
\t\t\t\t\t"}}}, "sells":{}, "clients":{"test":{"0":"
\t\t\t\t"}...

What I want is to delete all new line feed (\\n) & tab characters(\\t) from it and have a JSON string like this :

..."items":{},"buys":{}}}, "sells":{}, "clients":{"test":{}...

I have written a preg_replace function like this :

$json = preg_replace(['/\"0\"\:\n\"[\\t]+/'], [''], $json);

but When I log the JSON string they have not been deleted .

What should I do ?

Answer 1

You can use str_replace() function to replace the \\t and \\n :

$json = str_replace(array('\t','\n'),'',$json);

Answer 2

You may use this regular expression

"[\t\n\r]"
