PHP accept array parameters in the query string using the [ ] format
http://my.url/bar.php?foo[]=1&foo[]=2&foo[]=3&foo[]=4
I need to allow the format without square brackets
http://my.url/bar.php?foo=1&foo=2&foo=3&foo=4
I don't want to change my application so I thought about rewrite the second URL to the first one. Is this possible in NGINX?
I think the solution is achievable with a quite simple lua script.
You could:
loop get_uri_args()
accumulate multiple values for the same key in a new key[] variable
put the new args in place using set_uri_args()
Something like the following (not tested, ajust to your real case):
// "foo=val1&bar=baz%foo=val2"
location = /test {
content_by_lua_block {
local args = ngx.req.get_uri_args()
local qs = {}
for key, val in pairs(args) do
if type(val) == "table" then
table.insert(qs, key.."[]" .. table.concat(val, key.."[]"))
else
table.insert(qs, val)
end
end
// qs = { foo[] = {"val1", "val2"}, bar = "baz" }
ngx.req.set_uri_args(qs)
}
// "foo[]=val1&foo[]=val2&bar=baz"
}
Note: this has to be extended if you whant to take into account "multidimensional" arrays too.

I don't know the correct wording for this issue I am having.
I have a object returned from the database like below:
$pProvisioningFileData->m_fileContent = # Placeholders identified by '${}'
will be replaced during the provisioning
# process, only supported placeholders will be processed.
Dcm.SerialNumber = ${unit.serial_number}
Dcm.MacAddress = ${unit.mac_address}
Dcm.MinSeverity = "Warning"
Cert.TransferHttpsCipherSuite = "CS1"
Cert.TransferHttpsTlsVersion = "TLSv1"
Cert.MinSeverity = "Warning";
The curly brackets are placeholders, the problem I am facing is that when I try output all the content using either echo or print_r, all the content prints in one line however I want to display the content in the same sequence as above.
I tried using var_dump but it also gives some extra info like length and type of variable which I don't want.
So is there a simple way of doing this without using an array?
If you are outputting to browser then wrapping your var_dump in html <pre> tags is quick solution. If you outputting to console then I advise you to install some advanced debuging software. Xdebug comes to mind.
It is difficult from your question to understand exactly what you are wanting to do, but there are three ways you can print out the contents of an object. The third here, looping members, will give you more control and you can add a switch statement or other formatting to output precisely what you desire:
class unit {
var $serial_number;
var $mac_address;
}
$test = new unit;
$test->serial_number = "999";
$test->mac_address = "999.999.999.999";
/* Method 1 - print_r */
print_r($test);
print "\n\n";
/* Method 1 - var_dump */
var_dump($test);
print "\n\n";
/* Method 3 - looping members */
foreach ($test as $memberName => $member)
{
print "{$memberName}: {$member}\n";
}
I have a php script getting all folders in a posts folder and making them into a list.
I have a $postinfo_str variable assigned to a json file for each folder which I am using to store post date and category/tag info etc in.
I also have a $pagetitle variable assigned to a title.php include file for each folder. So say I am on a "June 2018" archive page, the text in that file will be "June 2018". If I am on say a "Tutorials" category page, that will be the text in the title.php.
In the json file, I have:
{
"Arraysortdate": "YYYYMMDD",
"Month": "Month YYYY",
"Category": ["cat1", "cat2", "etc"]
}
I am ordering the array newest to oldest using krsort with Arraysortdate as key.
How do I filter the array using $pagetitle as input, finding if there is a match in $postinfo_str, and if there isn't, remove that folder from the array?
All I can seem to find regarding array sorting is where the info in the $pageinfo_str is basically the array and so by that, the $title is the input and the output is the matching text from the $postinfo_str, whereas I want the output to be the folders that only have the matching text in the $postinfo_str to what the input ($pagetitle) is.
Here is my code I have.. Keep in mind this is flat file, I do not want a database to achieve this. See comments if you want an explaination.
<?php
$BASE_PATH = '/path/to/public_html';
// initial array containing the dirs
$dirs = glob($BASE_PATH.'/testblog/*/posts/*', GLOB_ONLYDIR);
// new array with date as key
$dirinfo_arr = [];
foreach ($dirs as $cdir) {
// get current page title from file
$pagetitle = file_get_contents("includes/title.php");
// get date & post info from file
$dirinfo_str = file_get_contents("$cdir/includes/post-info.json");
$dirinfo = json_decode($dirinfo_str, TRUE);
// add current directory to the info array
$dirinfo['dir'] = $cdir;
// add current dir to new array where date is the key
$dirinfo_arr[$dirinfo['Arraysortdate']] = $dirinfo;
}
// now we sort the new array
krsort($dirinfo_arr);
foreach($dirinfo_arr as $key=>$dir) {
$dirpath = $dir['dir'];
$dirpath = str_replace('/path/to/public_html/', '', $dirpath);
?>
<!--HTML HERE SUCH AS--!>
TEXT <br>
<?php
};
?>
I have difficulties following your problem description. Your code example is slightly confusing. It appears to load the same global includes/title.php for each directory. Meaning, the value of $pagetitle should be the same every iteration. If this is intended, you should probably move that line right outside the loop. If the file contains actual php code, you should probably use
$pagetitle = include 'includes/title.php';
or something similar. If it doesn't, you should probably name it title.txt. If it is not one global file, you should probably add the path to the file_get_contents/include as well. (However, why wouldn't you just add the title in the json struct?)
I'm under the assumption that this happened by accident when trying to provide a minimal code example (?) ... In any case, my answer won't be the perfect answer, but it hopefully can be adapted once understood ;o)
If you only want elements in your array, that fulfill certain properties, you have essentially two choices:
don't put those element in (mostly your code)
foreach ($dirs as $cdir) {
// get current page title from file
$pagetitle = file_get_contents("includes/title.php");
// get date & post info from file
$dirinfo_str = file_get_contents("$cdir/includes/post-info.json");
$dirinfo = json_decode($dirinfo_str, TRUE);
// add current directory to the info array
$dirinfo['dir'] = $cdir;
// add current dir to new array where date is the key
// ------------ NEW --------------
$filtercat = 'cat1';
if(!in_array($filtercat, $dirinfo['Category'])) {
continue;
}
// -------------------------------
$dirinfo_arr[$dirinfo['Arraysortdate']] = $dirinfo;
array_filter the array afterwards, by providing a anonymous function
// ----- before cycling through $dirinfo_arr for output
$filtercat = 'cat1';
$filterfunc = function($dirinfo) use ($filtercat) {
return in_array($filtercat, $dirinfo['Category']));
}
$dirinfo_arr = array_filter($dirinfo_arr, $filterfunc);
you should read up about anonymous functions and how you provide local vars to them, to ease the pain. maybe your use case is bettersuited for array_reduce, which is similar, except you can determine the output of your "filter".
$new = array_filter($array, $func), is just a fancy way of writing:
$new = [];
foreach($array as $key => $value) {
if($func($value)) {
$new[$key] = $value;
}
}
update 1
in my code samples, you could replace in_array($filtercat, $dirinfo['Category']) with in_array($pagetitle, $dirinfo) - if you want to match on anything that's in the json-struct (base level) - or with ($pagetitle == $dirinfo['Month']) if you just want to match the month.

I understand, that you're probably just starting with php or even programming, so the concept of some "huge database" may be frightening. But tbh, the filesystem is - from a certain point of view - a database as well. However, it usually is quite slow in comparison, it also doesn't provide many features.
In the long run, I would strongly suggest using a database. If you don't like the idea of putting your data in "some database server", use sqlite. However, there is a learning curve involved, if you never had to deal with databases before. In the long run it will be time worth spending, because it simplifys so many things.
re: Home Site = http://mobiledetect.net/
re: this script = Mobile_Detect.php
Download script here: https://github.com/serbanghita/Mobile-Detect
This script functions perfectly detecting the different parameters of a user's device.
However, this is how I am currently detecting these parameters:
// each part of the IF statement is hard-coded = not the way to do this
if($detect->isiOS()){
$usingOS = 'iOS';
}
if($detect->isAndroidOS()){
$usingOS = 'Android';
}
echo 'Your OS is: '.$usingOS;
My goal is to use a FOREACH to iterate thru the various arrays in this script to determine a user's device's parameters. I would need to have the "($detect->isXXXXOS())" be dynamic... (which, would be based upon the KEY). The results would display the KEY. But the detection would be based upon the VALUE.
Also, since my web page uses a REQUIRE to access this script... in the Mobile_Script.php script, the arrays are "protected." I think this is also causing me problems (but I don't know for sure).
Any help is appreciated.
In foreach loop you can call dynamic method look like this :
$array = array('Android','Windows','Linux','Mac');
foreach( $array as $value) {
$method = "is{$value}OS";
if($detect->$method()) {
$os = $value;
echo "Your OS is : {$os}";
}
}
Please rearrange your code what you want. I give you an example.
you can try to use somethin like this:
$OSList = $detect->getOperatingSystems();// will give array of operating system name => match params
foreach($OSList as $os_name=>$os_params/*unused*/)
{
$method = 'is'.$os_name;
if($detect->$method())
{
$usingOS = $os_name;
}
}
Ok so what i want to be able to do is to perform a suggestive style search using the contents of an array instead of a doing a mySQL database query on every keyup.
So imagine a javascript object or array that is full of people's names:
var array = (jack,tom,john,sarah,barry,...etc);
I want to then query the contents of this array based on what the user has typed into the input box so far. So if they have typed 'j',both jack and john will be pulled out of the array.
I know this is possible via php mysql and ajax calls, but for reason of optimization I would like to be able to query the js array instead.
Hope someone can help me with this!

as the name suggests, this finds elements of an array starting with the given string s.
Array.prototype.findElementsStartingWith = function(s) {
var r = [];
for(var i = 0; i < this.length; i++)
if(this[i].toString().indexOf(s) === 0)
r.push(this[i]);
return r;
}
// example
a = ["foo", "bar", "fooba", "quu", "foooba"];
console.log(a.findElementsStartingWith("fo"))
the rest is basically the same as in ajax-based scripts.
http://wwwo.google.com?q=autosuggest+using+javascript
AJAX calls fetch the contents from another serverside script files. You already have your data in the JS. Read a AJAX tutorial doing this. Then, just remove the parts where AJAX calls are made and replace it with your array's contents, and you're good to go.
I ended up using the following function to build my AJAX free instant search bar:
Example JS object being searched:
var $members = {
"123":{firstname:"wilson", lastname:"page", email:"wilpage#blueyonder.co.uk"},
"124":{firstname:"jamie", lastname:"wright", email:"jamie#blueyonder.co.uk"}
}
Example of function to search JS object:
$membersTab.find('.searchWrap input').keyup(function(){
var $term = $(this).val(),
$faces = $membersTab.find('.member'),
$matches = [];
if($term.length > 0){
$faces.hide();
$.each($members,function(uID,details){
$.each(details,function(detail,value){
if(value.indexOf($term) === 0){//if string matches term and starts at the first character
$faces.filter('[uID='+uID+']').show();
}
});
});
}else{
$faces.show();
}
});
It shows and hides users in a list if they partially match the entered search term.
Hope this helps someone out as I was clueless as to how to do this at first!

First off, I do not want what is in the URL query. I want what PHP see's in the$_GET array.
This is because the URL query will not show all the params if mod_rewrite has been used to make pretty URLs
So is there a way to get the query string that would match exactly what is in the php $_GET array?
--
I came up with a way myself using PHP and JavaScript like so:
function query_string()
{
<?php
function assoc_array_to_string ($arr)
{
$a = array();
foreach($arr as $key => $value)
{
$str = $key.'='.$value;
$a[] = $str;
}
return implode("&",$a);
}
?>
return '<?=urlencode(assoc_array_to_string($_GET))?>';
}
...but I need to do this with just javascript if possible because I can't put PHP code in a .js file.
Won't JavaScript "only see" the query string? How would client-side script know about any rewrite rules?
The only way I can think of is to use PHP -- echo it into a variable in an inline script in your main page rather than the JS file.
In your page <head>:
<script type="text/javascript">
var phpQueryParams = <?php print json_encode($_GET); ?>
</script>
Assuming at least PHP 5.2, otherwise use an external package
The query string is found in window.location.search, but that's the raw query string. So if you run something like this:
(function () {
QueryStr = {}
QueryStr.raw = window.location.search.substr(1);
var pairStrs = QueryStr.raw.split('&');
QueryStr.val = {}
for(var i=0,z=pairStrs.length; i < z; i++) {
var pair = pairStrs[i].split('=');
QueryStr.val[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1]);
}
})();
You'd have something very much like $_GET in QueryStr.val.
Of course, you mention that you've mixed things up a bit using mod_rewrite, which is cool, but since we don't know your rewrite scheme, we can't help specifically with that.
However... you know your rewrite scheme, and you could probably modify the code I gave above to operate on some other part of window.location. My bet is that you'd want to split window.location.pathname on the / character instead of &.
