PHP jSon data clean values for unwanted white spaces - php

Below is my JSON data which i get it by using
$json = json_encode($array);
my JSON Data;
{
"id":"352",
"date":"2013-12-25 01:10:06",
"category":"2",
"subtitle":null,
"description":" This text is description... ",
"hit":"144",
"rate":"50.00",
"active":"1"
}
Think that there are thousands of items like this.
But the problem is how can I trim the description value of this object automatically when running json_encode?
I dont wanna use "for each" because of performance i think.
Thanks...


use trim in array_map as :
$json = json_encode(array_map('trim',$array));

Decoding too many times encoded string in PHP

I get a string in PHP from an external database which looks like this:
$myStr = '<br>To send a note'
As you can see this string is encoded too many times, is there is a way to decode it all the way back using PHP?

What happened that your str passed lots of times through htmlentities().
The original string probably was <br>To send a note, then, the 1st time it become <br>To send a note, the secong it replace all & with & and so on.
In order to put it inside text area you should to decode it using:
<textarea><?php echo html_entity_decode($myStr); ?></textarea>
The code bellow will pass as many times it's necessary to solve your issue:
$modStr = $myStr = '&amp;amp;amp;amp;amp;amp;lt;br&amp;amp;amp;amp;amp;amp;gt;To send a note';
do {
$myStr = $modStr;
$modStr = html_entity_decode($myStr);
} while( $modStr != $myStr );

Json string conversion to json object

I have been stuck in this issue and cant seem to fix it.. I have this JSON STRING
$unBillableArr = ["{'id' : '123','to' : '+923412268656','MsgReceivedFrom' : '03349433314', 'message':'Qwertyy ', 'recdate':'2017-11-20 19:01:49'}"];
I need to convert it into array of object or maybe just one json object.. I have tried doing
json_decode($unBilledArr , true);
It gives me null.
Already tried these solutions as well
Convert a string to JSON object php
https://jonsuh.com/blog/convert-loop-through-json-php-javascript-arrays-objects/
I must be doing something wrong.. cant seem to figure out what..
P.s : This is the response i am getting and i can not do anything about the response.

You are trying to decode an array, either specify the specific item within the array, or make it a string.
For instance:
$unBillableArr = '{"id":"123", "to":"+923412268656", "MsgReceivedFrom":"03349433314", "message":"Qwertyy", "recdate":"2017-11-20 19:01:49"}';
$json = json_decode($unBillableArr, true);
// Or
$unBillableArr = ['{"id":"123", "to":"+923412268656", "MsgReceivedFrom":"03349433314", "message":"Qwertyy", "recdate":"2017-11-20 19:01:49"}'];
$json = json_decode($unBillableArr[0], true);
However, given the string you are receiving does not contain valid JSON and you are unable to control what you receive, I have prepared the following that will replace the single quotes in your JSON, and decode each item into an array:
$unBillableArr = ["{'id' : '123','to' : '+923412268656','MsgReceivedFrom' : '03349433314', 'message':'Qwertyy ', 'recdate':'2017-11-20 19:01:49'}"];
// Loop through each JSON string
$jsonObjects = []; // Change this name...
foreach ($unBillableArr as $jsonString) {
$jsonObjects[] = json_decode(str_replace("'", '"', $jsonString), true);
}
print_r($jsonObjects); // Proof it works
Please bear in mind that I would consider this to be a dirty fix. To fix this properly, you should go back to the source and ensure that the JSON they are returning to you is valid.

Formatting JSON formatted text file in PHP

So I got a HTML page with a button. When I click the button, a separate javascript file sends a GET request to my PHP file, expecting a JSON object in return. My PHP reads a JSON formatted text file and should convert it into a JSONObject and echo it out for my javascipt. I had some code working before, but it doesn't seem to do it anymore since I changed to a Ajax aproach instead of having everything in the same file. This is my code:
readLog.php
<?php
class test{
function clean($string){
return json_decode(rtrim(trim($string),','),true);
}
function getLog(){
header('Content-Type: application/json');
$logLines = file('../../../home/shares/flower_hum/humid.log');
$entries = array_map("clean",$logLines);
$finalOutput = ['log' => $entries];
echo json_encode($logLines);
}
}
?>
My humid.log file looks like this:
{"date":"26/09/2016", "time":"22:40:46","temp":"16.0", "humidity":"71.0" }
{"date":"26/09/2016", "time":"23:10:47","temp":"16.0", "humidity":"71.0" }
Now If I press my button, this is the response I get checking the console in my web browser:
Response:
["{\"date\":\"26\/09\/2016\", \"time\":\"22:40:46\",\"temp\":\"16.0\", \"humidity\":\"71.0\" }{\"date\":\"26\/09\/2016\", \"time\":\"23:10:47\",\"temp\":\"16.0\", \"humidity\":\"71.0\" }\n"]
JSON:
"{"date":"26/09/2016", "time":"22:40:46","temp":"16.0", "humidity":"71.0" }{"date":"26/09/2016", "time":"23:10:47","temp":"16.0", "humidity":"71.0" }\n"
obviously something is wrong with the formatting, but I don't know what. As I said, this code worked just fine when I had my php and HTML in the same file.
EDIT:
I have also tried formatting the JSON with something like this, but it just prints the brackets:
function getLog(){
$text = file('../../../home/shares/flower_hum/humid.log');
$textRemoved ="["; //Add opening bracket.
$textRemoved .= substr($text, 0, strlen($text)-1); (Remove last comma)
$textRemoved .="]";//Add closing bracket
$json = json_encode($textRemoved);
echo $json;
}

So I managed to solve it myself. Basicly The formatting of the textfile was wrong and as some commentors said, I don't need to encode it if I am doing it myself. What I ended up doing was in my application that generates the log file to add comma after each row. Then in my PHP I added brackets and removed the last comma.
function getLog(){
header('Content-Type: application/json');
$file = file_get_contents('../../../home/shares/flower_hum/humid.log');
$lengthOfFile = strlen($file)-2;
$subFile = substr($file, 0, $lengthOfFile);
$res ="[";
$res .= $subFile;
$res .="]";
echo $res;
}

You can't just jam two+ JSON strings togther. It's JSON, which means it HAS to be syntactically correct Javascript CODE. If you want to join two json strings together, you HAVE to decode them to a native data structure, join those structures together, then re-encode the new merged structure:
$temp1 = json_decode('{"foo":"bar"}', true);
$temp2 = json_decode('{"baz":"qux"}', true);
$new = array_merge($temp1, $temp2);
echo json_encode($new);
which will produce:
{"foo":"bar","baz":"qux"}
and remain valid JSON/Javascript.
Why? Consider that bare integers are valid json:
json_encode(42) -> 42
json_encode(123) -> 123
If you have two json-encoded integers and jam together, you get a "new" integer:
42123
and on the receiving end, you'll be going "Ok, so where is the split between the two", because 4 and 2123 are just as valid as possible original values as 4212 and 3.
Sending the two integers as distinct and SEPARATABLE values would require an array:
[42,123]

strip_tags truncating JSON

I have a JSON Response like this:
{
"id":"2461",
"name":"GEORGIA INSTITUTE OF <leo_highlight style=border-bottom: 2px solid rgb(255, 255, 150); background-c",
"logo":"",
"address":null,
"city":null,
"state":null,
"campus_uri":"{{PATH}}2461\/"
},
....
....
When I do strip_tgs on this one, the whole JSON string is getting truncated at the name tag above. The JSON string looks like this.
{"id":"2461","name":"GEORGIA INSTITUTE OF
All below this line is gone. This is a huge JSON. But its getting truncated here.
Any ideas on what to do? I need to strip out all HTML tags.
Update:
Adding more details...
This JSON string I got is from encoding the query results array. So I get array from MySQL query and I encoded it with json_encode and trying to strip_tags on it.

$array = json_decode($json, true);
array_walk_recursive($array, function (&$val) { $val = strip_tags($val); });
$json = json_encode($json);
As simple... Decode it, walk through and encode it.

Strip out the tags after you have decoded the JSON object. You might do this in a lazy fashion (i.e. when needed) rather than go through every item an strip tags on all fields.

PHP preg_match_all/preg_match

I am trying to create a report function for our firewall.
The firewall rules are stored in json format.
Here is a sample of the string.
[{"id":1,"enabled":true,"description":"TEMP","matchers":{"javaClass":"java.util.LinkedList","list":[{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1.1.1.1","matcherType":"DST_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"80","matcherType":"DST_PORT"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,3,2","matcherType":"DST_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"2.2.2.2","matcherType":"SRC_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,2,wan","matcherType":"SRC_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"UDP,TCP,any","matcherType":"PROTOCOL"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"svrbjgu","matcherType":"DIRECTORY_CONNECTOR_USERNAME"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"intern-it","matcherType":"DIRECTORY_CONNECTOR_GROUP"}]},"ruleId":5001,"javaClass":"com.untangle.node.firewall.FirewallRule","block":false,"log":true}]
And the preg_match_all filter i have:
preg_match_all('/\"description":"(.*?)\","matchers"/',$str,$description);
preg_match_all('/\"id":(.*?)\,"/',$str,$id);
preg_match_all('/\"ruleId":(.*?)\,"/',$str,$rule_id);
preg_match_all('/\"enabled":(.*?)\,"description"/',$str,$enable);
preg_match_all('/\"block":(.*?)\,"/',$str,$block);
preg_match_all('/\"log":(.*?)\}/',$str,$log);
preg_match_all('/\"value":"(.*?)\","matcherType":"DST_ADDR"/',$str,$dest_add);
preg_match_all('/\"value":"(.*?)\","matcherType":"DST_PORT"/',$str,$dest_port);
preg_match_all('/\"value":"(.*?)\","matcherType":"DST_INTF"/',$str,$dest_int);
preg_match_all('/\"value":"(.*?)\,","matcherType":"SRC_ADDR"/',$str,$src_add);
preg_match_all('/\"value":"(.*?)\","matcherType":"SRC_INTF"/',$str,$src_int);
preg_match_all('/\"value":"(.*?)\","matcherType":"PROTOCOL"/',$str,$protocol);
preg_match_all('/\"value":"(.*?)\","matcherType":"DIRECTORY_CONNECTOR_USERNAME"/',$str,$user);
preg_match_all('/\"value":"(.*?)\","matcherType":"DIRECTORY_CONNECTOR_GROUP"/',$str,$group);
What happens is that the start for evry matcher is VALUE":" when i print $dest_port i get "1.1.1.1","matcherType":"DST_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"80" instead of just 80.
Any one that have a preg_match_all to find the matchertype first and then read backwords to the "value":"?
Any help would be fantastic!

$xyz = <<<EOX
[{"id":1,"enabled":true,"description":"TEMP","matchers":{"javaClass":"java.util.LinkedList","list":[{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1.1.1.1","matcherType":"DST_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"80","matcherType":"DST_PORT"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,3,2","matcherType":"DST_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"2.2.2.2","matcherType":"SRC_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,2,wan","matcherType":"SRC_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"UDP,TCP,any","matcherType":"PROTOCOL"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"svrbjgu","matcherType":"DIRECTORY_CONNECTOR_USERNAME"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"intern-it","matcherType":"DIRECTORY_CONNECTOR_GROUP"}]},"ruleId":5001,"javaClass":"com.untangle.node.firewall.FirewallRule","block":false,"log":true}]
EOX;
var_dump(json_decode($xyz)); //execute other operations, iteration etc here
This works much better than regex. Returns structured data, you can iterate through.

Ended up using with json_decode.
sample:
$jsondata ='[{"id":1,"enabled":true,"description":"TEMP","matchers":{"javaClass":"java.util.LinkedList","list":[{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1.1.1.1","matcherType":"DST_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"80","matcherType":"DST_PORT"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,3,2","matcherType":"DST_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"2.2.2.2","matcherType":"SRC_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,2,wan","matcherType":"SRC_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"UDP,TCP,any","matcherType":"PROTOCOL"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"svrbjgu","matcherType":"DIRECTORY_CONNECTOR_USERNAME"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"intern-it","matcherType":"DIRECTORY_CONNECTOR_GROUP"}]},"ruleId":5001,"javaClass":"com.untangle.node.firewall.FirewallRule","block":false,"log":true}]';
$data = json_decode($jsondata,true);
echo '<table><tr><th WIDTH="10">Nr.</th><th WIDTH="10">RuleID</th><th WIDTH="150">Description</th><th WIDTH="100">Protocol</th><th WIDTH="75">Src Int</th><th WIDTH="150">Src Address</th><th WIDTH="100">Src Port</th><th WIDTH="75">Dest. Int</th><th WIDTH="150">Dest Address</th><th WIDTH="100">Dest. Port</th><th WIDTH="50">Action</th><th WIDTH="50">Log</th><th WIDTH="50">Enabled</th></tr>';
echo "<tr><td>test.</td><td> {$data[0]['ruleId']} </td><td>{$data[0]['description']}</td><td>{$data[0]['enabled']}</td></tr>" ;
