I think ham to stupid for it :) I can't figured out whats wrong. I try to search at goole for the problem but think I don't use the correct phrases ... so I hope you can help me and my brain
Problem:
$mydata = $data['device']['26']['state']['1'];
Thats my code to readout json data. all is perfect. So my only problem is
['26']
this value is in an config file which is included, how can I use for expl.
$id
instead of ['26'] ... i want a littlest flexibility in this script but can't figured out how I do this.
thanks so much
$mydata = $data['device'][$id]['state']['1'];

I'm pulling google map data into a php array from MySQL. I have used this code as a base:
https://github.com/rajkavinchetty/Google-Maps-API-with-PHP-MySQL/blob/master/index.php
It almost works perfectly. The lat/long data is pulled from the array and sets-up the markers.
...
$locations[]=array( 'name'=>$name, 'lat'=>$latitude, 'lng'=>$longitude, 'lnk'=>$link );
...
But I'm having problem with the Title/Content of the infowindow.
With the base example I'm using, the content is formatted as a link:
var locations = [
<?php for($i=0;$i<sizeof($locations);$i++){ $j=$i+1;?>
[
'AMC Service',
'<p><?php echo $locations[0]['name'];?></p>',
<?php echo $locations[$i]['lat'];?>,
<?php echo $locations[$i]['lng'];?>,
0
]<?php if($j!=sizeof($locations))echo ","; }?>
];
but the variable pulls only the first link and name from the array, it does not go through the loop. I have tried many different variables, such as
<?php echo $locations[$i]['name'];?>
but this gives an error.
I'm not an expert in either php arrays or loop or java, so I'm fumbling around for clues. I've looked through all of the related questions here for help, and also consulted the Google stack as well.
Any help would be appreciated.
UPDATE:
The first three replies were useful, thank you, but no there yet.
After the comment from Andy, and encouragement from Divyamohan that the original solution should have worked, I realised that there must be some json formatting problem, so I tried:
<?php echo json_encode($locations[$i]['name']);?>
This worked and now I'm able to have these loop through.
But still trying to get this to work as an href link. I tried to solve with backslashes as Hardik and David observed, but still this does not work. Half way there.
'<p><?=$locations[$i]["name"]?></p>'
Just Replace this in your code and it should work.
You need to change this line
'<p><?php echo $locations[0]['name'];?></p>'
to
'<p><?php echo $locations[0][\'name\'];?></p>'
You need to add backslash ( \ ) character to escape quote from string literals.
So finally I found the solution to the problem. Thanks to the comments from everyone that helped me to look at it another way.
In the end, the problem was not with the code. The problem was the data. This should have been obvious. In the links column I had URLs with slashes and text in the names column included apostrophes and foreign characters. These combined were throwing off the json errors. I cleaned all the data and the modified code works perfectly.
<p><?=$locations[$i]['name']?></p>
Many thanks again for the comments.
i hope you may be able to help me out.
I am building a scrape script using simple html dom.
I have a few sites where i need to get the thumbnail path, name of the movie and some other stuffs. I have build me an admin panel where i save in plaintext the methods required to find that stuff based on the matching pattern.
Eg.
$movie_name = $result->children(0)->children(0)->innertext;
This works just like it supposed to work but when i save children(0)->children(0)->innertext in the database and then back into variable, eg,
$variable = "children(0)->children(0)->innertext";
$movie_name = $result->$variable;
it does not work.
I am pretty sure i am going horribly wrong about this, so please give me a hint how i could just save the methods in plaintext and then call them.
It must be stored in plaintext because the dom is frequently changing so i will be able to keep up with it.
Best regards.
You're looking for the PHP eval() function:
$movie_name = $result->eval($variable);
Having said that, be warned that eval is evil.
Instead, I would recommend xpath.
Hope this helps!
Got it, eval() was the answer. Since no user input is going to the eval() its pretty safe in my particular case. Just had to do some escaping and declaring the variable containing the method inside eval();
This piece of code works for me.
$res_mov_url_e = eval("\$res_mov_url = \$result->$movie_url;");
Anyway big thanks guys!
So I am having problems with the symbol µg in PHP. The symbol is inside an array of data but I can't seem to match it with the following:
if($value == 'µg') {
echo 'blah';
}
Does anyone happen to have a work around for this? I'm assuming PHP saves it as a different type then what I am comparing it to because it never echo's the 'blah' above. I have searched around for a while now and cannot find anything to help me. Thanks!
Okay so even with the help of some people I haven't found the answer.
The best I came up with that actually works is:
substr('µg', 1,7) == 'micro;g'
That's the only way I found out how to parse the data. If you put the & in front of the micro; you get the µ. A dirty fix but if anyone has a way around please let me know. Thanks!
yeah, I know, the title is kind of confusing, but no better title came to my mind.
Here is my problem:
I want to use a link in my application, which would look like this:
localhost/index?jumpto=some_folder/somescript.php?someparam1=1234&someparam2=4321
The problem is that &someparam2 is meant to hang on the second $_GET-Param.
It would be like this:
localhost/index?jumpto=some_folder/somescript.php?someparam1=1234&someparam2=4321
Instead, PHP interprets that &someparam2 hangs on the first $_GET-Param.
localhost/index?jumpto=some_folder/somescript.php?someparam1=1234&someparam2=4321
Does anyone know a solution for this?
I already tried
localhost/index?jumpto='some_folder/somescript.php?someparam1=1234&someparam2=4321'
but of course that didn't work.
I hope you can understand my problem.
Thank you for your time.
You will need to URL encode your string some_folder/somescript.php?someparam1=1234 so that php will not parse & in the query string as a param separator.
use urlencode("some_folder/somescript.php?someparam1=1234");
I have a file that I'm trying to decode but I'm not sure the best way to go about doing it. I've tried putting it through a few online tools but haven't had much luck...the code looks like this:
<?php
$zAkSoSavjFOn='jumbledcodeinhere';
$THkNltHSOjsXfQLzr=';))))aBSwinFbFxNm$(ireegf(rqbprq_46rfno(rgnysavmt(ynir';
$DzbOntpeGhMcan=strrev($THkNltHSOjsXfQLzr);
$WnJYuMUwKmRxBh=str_rot13($DzbOntpeGhMcan);
eval($WnJYuMUwKmRxBh);
?>
In all my playing I managed to extract the following with a php script:
eval(gzinflate(base64_decode(strrev($zAkSoSavjFOn))));
Could someone point me in the right direction on going about this process? Any help would be appreciated. :)
The "jumbled code" is gzipped, base64-encoded, reversed PHP code that is almost certainly malicious.
Replace eval with echo and see what it gives you, that's what the code that is trying to run is.
