How to remove backslashes from json response in php

What do you mean by "not working"?

<?php

$unescapedJson = '{\"id\":\"order_DPUVoS2YVnBccy\",\"entity\":\"order\",\"amount\":100,\"amount_paid\":0,\"amount_due\":100,\"currency\":\"INR\",\"receipt\":\"7550\",\"offer_id\":null,\"status\":\"created\",\"attempts\":0,\"notes\":[],\"created_at\":1570082483}';

echo stripslashes($unescapedJson);

Output for PHP 7.1.25 - 7.4.0rc2:

{"id":"order_DPUVoS2YVnBccy","entity":"order","amount":100,"amount_paid":0,"amount_due":100,"currency":"INR","receipt":"7550","offer_id":null,"status":"created","attempts":0,"notes":[],"created_at":1570082483}

remove backslash from json string

You can try the following way to achieve what you need,

$jsonString = '\"[\n      {\n        \"id\": \"1\",\n        \"mid\": \"1\",\n        \"num\": \"1\",\n        \"type\": \"wgp\",\n        \"time_changed\": \"time\",\n        \"username\": \"aaa\"\n      }\n    ]\"';

$jsonString = str_replace('\\n', '', $jsonString); // First remove the new line characters in the json string

$jsonString = str_replace('\\', '', $jsonString); // Replace backslash with empty string

echo preg_replace('!\s+!', ' ', $jsonString); // Replace multiple spaces with one

So the output is,

"[ { "id": "1", "mid": "1", "num": "1", "type": "wgp", "time_changed":
"time", "username": "aaa" } ]"

Remove added backslashes from JSON string in Laravel

Try json_decode(your_data) this should work.

How to deal with backslashes in json strings php

The answer is in the question:

$jsonEncodedString = json_encode($object);
echo $jsonEncodedString;
// Result of echo being:
// {"namespace":"myCompany\\package\\subpackage"}

You don't have to strip any slashes. On the contrary. You have to express the echo-ed text as PHP source code.

$yetAnotherObject = json_decode('{"namespace":"myCompany\\\\package\\\\subpackage"}');

The backslash (\) is a special character in both PHP and JSON. Both languages use it to escape special characters in strings and in order to represent a backslash correctly in strings you have to prepend another backslash to it, both in PHP and JSON.

Let's try to do the job of the PHP parser on the string above. After the open parenthesis it encounters a string enclosed in single quotes. There are two special characters that needs escaping in single quote strings: the apostrophe (') and the backslash (\). While the apostrophe always needs escaping, the PHP interpreter is forgiving and allows unescaped backslashes as long as they do not create confusion. However, the correct representation of the backslash inside single quoted strings is \\.

The string passed to function json_decode() is

{"namespace":"myCompany\\package\\subpackage"}

Please note that this is the exact list of characters processed on runtime and not a string represented in PHP or any other language. The languages have special rules for representing special characters. This is just plain text.

The text above is interpreted by function json_decode() that expects it to be a piece of JSON. JSON is a small language, it has special rules for encoding of special characters in strings. The backslash is one of these characters and when it appears in a string it must be prepended by another backslash. JSON is not forgiving; when it encounters a backslash it always treats it as an escape character for the next character in the string.

The object created by json_decode() after successful parsing of the JSON representation you pass them contains a single property named namespace whose value is:

myCompany\package\subpackage

Note again that this is the actual string of characters and not a representation in any language.

What went wrong?

Back to your code:

$yetAnotherObject = json_decode('{"namespace":"myCompany\\package\\subpackage"}');

The PHP parser interprets the code above using the PHP rules. It understands that the json_decode() function must be invoked with the text {"namespace":"myCompany\package\subpackage"} as argument.

json_decode() uses its rules and tries to interpret the text above as a piece of JSON representation. The quote (") before myCompany tells it that "myCompany\package\subpackage" must be parsed as string. The backslash before package is interpreted as an escape character for p but \p is not a valid escape sequence for strings in JSON. This is why it refuses to continue and returns NULL.

how to remove slashes from json response in laravel

Try

var finalData = str.replace(/\\/g, ""); 
alert(yourdata);

OR

json_encode($yourdata, JSON_UNESCAPED_SLASHES);

OR

echo str_replace('\/','/',json_encode($yourdata));

OR

You have to decode the JSON twice, e.g.

var data = JSON.parse(JSON.parse(json).yourdata));

Hope any of this will helps you!!
