PHP - Validate Url Function, Which Support Http:// , And Www.

Hi,
 I'm migrating a site from PHP4 (4.4.6) to PHP5 (5.3.5), am replacing all short open tags, and have many '<?=' opening tags to migrate as well.
 I saw a reference in the online docs about an equivalent '<?php=' tag, but it doesn't appear to work.
 What is the best way to 'find and replace' a PHP4 snippet like '<?= $var ?>' into a PHP5, non-short-open-tag equivalent?
 thanks,
  Barry

Hey there,

I'm having a issue when I edit the XML file from a string here. Now the SimpleXML functions edit the nodes of the XML file perfectly and everything is done the way I want but upon returning the file to a string it keeps putting a XML content type at the top of the file, E.G:

Before XML File Is Edited:

Code: [Select]
<settings>
<!-- Port the server will listen on -->
<port>7781</port>

<!-- Maximum number of players the server will support (Max 32) -->
<maxplayers>10</maxplayers>

<!-- Maximum number of vehicles the server will support (Max 140) -->
<maxvehicles>100</maxvehicles>

<!-- Password clients will have to enter to connect -->
<!-- password>None</password -->

<!-- Add the server to the master list -->
<listed>true</listed>

<!-- The hostname players will see -->
<hostname>IV:MP Server</hostname>

<!-- The address the server will bind to -->
<!-- hostaddress>127.0.0.1</hostaddress -->

<!-- Toggles frequently called events which has impact on CPU usage  -->
<frequentevents>false</frequentevents>

<!-- The scripts the server will load and run -->
<script>cp.nut</script>
<script>whisper.nut</script>
<script>namecheck.nut</script>
<script>runcode.nut</script>

<!-- The modules the server will load and run -->
<!-- For windows: -->
<!-- module>Sample.dll</module -->
<!-- For linux: -->
<!-- module>Sample.so</module -->
</settings>

After XML File Is Edited

Code: [Select]
<?xml version=1.0?>
<settings>
<!-- Port the server will listen on -->
<port>7781</port>

<!-- Maximum number of players the server will support (Max 32) -->
<maxplayers>10</maxplayers>

<!-- Maximum number of vehicles the server will support (Max 140) -->
<maxvehicles>100</maxvehicles>

<!-- Password clients will have to enter to connect -->
<!-- password>None</password -->

<!-- Add the server to the master list -->
<listed>true</listed>

<!-- The hostname players will see -->
<hostname>IV:MP Server</hostname>

<!-- The address the server will bind to -->
<!-- hostaddress>127.0.0.1</hostaddress -->

<!-- Toggles frequently called events which has impact on CPU usage  -->
<frequentevents>false</frequentevents>

<!-- The scripts the server will load and run -->
<script>cp.nut</script>
<script>whisper.nut</script>
<script>namecheck.nut</script>
<script>runcode.nut</script>

<!-- The modules the server will load and run -->
<!-- For windows: -->
<!-- module>Sample.dll</module -->
<!-- For linux: -->
<!-- module>Sample.so</module -->
</settings>

Notice the addition to the header of the file "<?xml version=1.0?>". This is causing issues when the XML file is read by the server. Could anybody help me stop the SimpleXML editor from placing this in the header of the file? Thanks.

Hello. I'm working on a site which I'd prefer to use SVG for some of the images. However, since not all browsers support SVG, I'm going to set a global variable to true if I detect the browser supports SVG. Using this, I can check to see if SVG is supported and show PNG/gif/jpg images in the place of the SVG in older browsers (and add a small banner at the top prompting them to upgrade to a modern browser). I can already do this using javascript. But seeing as javascript can be disabled, newer browsers that can support SVG might not be fed those images (which are much smaller files).

The javascript I'm using to test SVG support is as follows

Code: [Select]
document.implementation.hasFeature("http://www.w3.org/TR/SVG11/feature#Shape", "1.1")
the php code I tried, seeing as how it would make sense, is the following

DOMImplementation::hasFeature("http://www.w3.org/TR/SVG11/feature#Shape", "1.1")

(both of those were used in conditional branches)

Is there any way to get php to test for SVG support? Or do I need to stick with javascript?

Thanks for reading!

Hey Everyone, I was hoping someone out there could help me figure something out. I am trying to create a ticket database, when I create a ticket, I give the option to upload a file, which works ok. But I am stumped at trying to display mulitply files to one ticket. If I have a ticket no 0001 and two files associted to 0001, i end up printing two 0001 tickets each with a single file. I want to print one 0001 with both files listed under it. I'm not sure if it's possible to do a while within a while so I hoping someone can help me figure that out.

Thanks for your help

Hi everyone,   I'm hoping the someone can guide me in the right direction for what I need to do. Does anyone know of a really good tutorial and/or information about a plugin product that is available to do what I need? For example, what I need is to create a website that has the ability to allow video conferencing between a teacher and students. This what I envision - a college professor can log on to his website and display a live video feed of him. Also, as each of his students log on, their live video feed is then also supplied. Would prefer a already made plugin product but would also like to look at raw code in PHP to see how something like this could be accomplished. Thank you in advance.   Charles

I think it's fsockopen that enables you to do web requests right?? I was wondering if you could also make it use a proxy instead of your website's IP. Would that be possible?

As written here i am trying todo the php remote support. What i was wondering is in sections line $ret .= 'cd client && ..\\win\\'.filename7z ' a ' etc, why does the user use \\ instead of a single \ and whats with the &&? i have the original php file and it reads $ret .= shell_exec('cd client;' . $filename7Z . ' a '' etc Now i know the original was made for Xampp in windows but i can get it nor this guys version to work. I assume that the \\ and && are specific to windows file systems but i can figure out how. I am trying to modify it to work on my 2k8r2 server or win7(running xampp) but get dead ends in both places. My Ubuntu server is a whole diff animal. can anyone give me any guidance?

I have an array of proxies and I need one to be chosen randomly and applied to each curl handle. This script runs successfully when proxy support is removed, but as soon as I try to add a proxy it refuses to connect. My proxies are good. I have private proxies that validate by confirming that the IP address of the requester is on a whitelist of IPs I configured. I've also tried working public proxies with no validation, with the same result. The error it returns is that it "cannot connect to google.com:3238". Why it's trying to connect to that port is beyond me, the proxies I use, their port is 3238, but it should be connecting to IP:PORT then Google.com:80. Not sure why it's mixing them up.  Here's my code:

Code: [Select]
function multi($urls,$proxies,$agents,$referer) {

// create the multi curl handle
$mh = curl_multi_init();
$handles = array();
$i = 0;
foreach ($urls as $url) {
// create a new single curl handle
$ch = curl_init();

// setting several options like url, timeout, returntransfer
// simulate multithreading by calling the wait.php script and sleeping for $rand seconds
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxies[rand(0,count($proxies))]);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_REFERER, $referer);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);

// add this handle to the multi handle
curl_multi_add_handle($mh,$ch);

// put the handles in an array to loop this later on
$handles[] = $ch;
$i++;
}

// execute the multi handle
$running=null;
do {
curl_multi_exec($mh,$running);
// added a usleep for 0.25 seconds to reduce load
usleep (250000);
} while ($running > 0);

echo 'Curl error: ' . curl_error($ch)."<br />".print_r(curl_getinfo($ch));

// get the content of the urls (if there is any)
for($i=0;$i<count($handles);$i++) {
// get the content of the handle
$output[] = curl_multi_getcontent($handles[$i]);

// remove the handle from the multi handle
curl_multi_remove_handle($mh,$handles[$i]);
}
// close the multi curl handle to free system resources
curl_multi_close($mh);

// echo the output to the screen
return $output;
 }
I only post on forums as a last resort. Typically a few Google searches solves the problem, but I've spent too much time researching this one with no progress. I'm assuming it's simply a parameter that needs to be added to the CURL handles, but I've tried every proxy related config option out there and still no dice.

I'm pretty new to PHP, and by new, I mean I have never done it or any other form of coding before starting my job a month or so ago. I've basically been manually trying to pick up PHP as I go. The website that I am working on had its core built, but I am trying to add functionality to it.

The website already had the contact for that you can see he http://www.janova.us/index.php/contact
The form would submit an email to an email address based on which subject was picked.


I have since added a simple file upload field. My problem, however, is tying in the form to the email. I need to upload it and then send it as an attachment with the email.

Here is what I am working with currently:

I have commented the changes I have added to the original code so that you can see what I have done. Any input on this would be greatly appreciated. Thanks.

I've asked this question before but still haven't really figured out how best to implement it, and have found myself hitting another roadblock.

I have multiple types of charts (i.e. bar, pie, etc), and various endpoints to access them.  I like to keep my routing script uncluttered, and feel the following does so.

$app->get('/chart', function (Request $request, Response $response) {
    //List of chart with optional filtering
    $this->chartService->index($request->getQueryParams());
    return $this->chartResponder->index($response, $index);
});

$app->post('/chart', function (Request $request, Response $response) {
    //Create a new chart of type (i.e. bar, pie, etc) specified by type parameter
    $chart=$this->chartService->create($request->getParsedBody());
    return $this->chartResponder->create($response, $chart);
});

$app->get('/chart/{id:[0-9]+}', function (Request $request, Response $response, $args) {
    //View chart of given ID
    $chart=$this->chartService->detail((int)$args['id']);
    return $this->chartResponder->delete($response, $chart);
});

$app->delete('/chart/{id:[0-9]+}', function (Request $request, Response $response, $args) {
    //Delete chart of given ID
    $this->chartService->delete((int)$args['id']);
    return $this->chartResponder->delete($response, null);
});

$app->post('/chart/{id:[0-9]+}/series', function (Request $request, Response $response, $args) {
    //Add a new series to the collection for chart with given ID
    $chart=$this->chartService->addSeries((int)$args['id'], $request->getParsedBody());
    return $this->chartResponder->update($response, $chart);
});

$app->put('/chart/{id:[0-9]+}/series/{seriesPosition:[0-9]+}', function (Request $request, Response $response, $args) {
    //Modify series of given position in the collection for chart with given ID
    $chart=$this->chartService->updateSeries((int)$args['id'], (int)$args['seriesPosition'], $request->getParsedBody());
    return $this->chartResponder->update($response, $chart);
});

//More endpoints for chart of given ID...

I then created the following service to support the endpoints.  Off topic, but is this a service or a controller?

My index() method is chart type agnostic.  My create() method needs a means to determine what type of chart to create, and does so using the received chart "type" passed in the body to get the applicable repository.  All the other methods receive the chart ID in the URL path and use it to first get the chart entity and then get the applicable repository based on the object.  All seems good!

<?php
namespace NotionCommotion\ChartBuilder\Service;
use NotionCommotion\ChartBuilder\Entity\Chart;

class ChartService
{
    protected $em;
    
    public function __construct(\Doctrine\ORM\EntityManager $em)
    {
        $this->em = $em;
    }

    public function index(array $params=[]):array {
        return $this->em->getRepository(Chart::class)->index($params);
    }

    public function create(array $params):Chart {
        //Get the specific repo based on $params['type].  Not perfect, but good enough
        $discriminatorMap=$this->em->getClassMetadata(Chart::class)->discriminatorMap;
        $repo = $this->em->getRepository($discriminatorMap[$params['type']]);
        //Validate data
        $chart=$repo->create($params);
        $this->em->persist($chart);
        $this->em->flush();
        return $chart;
    }

    public function read(int $id):Chart {
        return $this->em->getRepository(Chart::class)->find($id);
    }

    public function delete(int $id):void {
        $this->em->remove($this->read($id));
        $this->em->flush();
    }

    public function addSeries(int $idPublic, array $id):Chart {
        $chart=$this->read($id);
        //Validate data
        $repo=$this->em->getRepository(get_class($chart));
        $repo->addSeries($chart, $params);
        $this->em->persist($chart);
        $this->em->flush();
        return $chart;
    }

    public function updateSeries(int $id, int $position, array $params):Chart {
        $chart=$this->read($id);
        $series=$chart->getSeries();
        $seriesNode=$series->offsetGet($position);
        //Validate data
        $repo=$this->em->getRepository(get_class($seriesNode));
        $repo->update($seriesNode, $params);
        $this->em->persist($chart);
        $this->em->flush();
        return $chart;
    }
}

Until...  I find myself needing to put non-database related functionality in the repository and violating the single responsibility principle.  I am not a complete purist and might be willing to do so, however, there does not appear to be a clean way to inject dependencies in a Doctrine repository.

One thought I had was to create specialized services maybe as follows:

$c['chartService'] = function ($c) {
    return new ChartService(
        $c[EntityManager::class],
        [
            'bar'=>function ($c) {return new BarChartService($c[EntityManager::class]);},
            'pie'=>function ($c) {return new PieChartService($c[EntityManager::class], $c['someOtherObject']);},
            //add more types...
        ]
    );
};

 

class ChartService
{
    protected $em, $subServices=[];
    
    public function __construct(\Doctrine\ORM\EntityManager $em, $subServices)
    {
        $this->em = $em;
        $this->subServices = $subServices;
    }

    public function index(array $params=[]):array {/* no change */}

    public function create(array $params):Chart {/* maybe no change */}

    public function __call($name, $args) {
        $chart=$this->em->getRepository(Chart::class)->find($args[0]);
        $subservice=$this->getSubservice($chart);
        $args[0]=$chart;
        return $subservice->$name(...$args);
    }
}

abstract class AbstractSpecificChartService
{
    protected $em;
    
    public function __construct(\Doctrine\ORM\EntityManager $em)
    {
        $this->em = $em;
    }

    public function __call($name, $args) {
        throw new \Exception("Method $name not supported");
    }

    protected function getSubservice(Chart $chart):self {
        //Haven't figured out but can do so if needed.
    }

    public function delete(Chart $chart):void {
        //Include methods common to all charts here
        $this->em->remove($chart);
        $this->em->flush();
    }

    protected function helperMethods($foo) {
        //If necessary.
    }
}

class BarChartService extends AbstractSpecificChartService
{
    //Override __construct if necessary

    public function updateSeries(Chart $chart, int $position, array $params):Chart {
        //Note that Chart and not $id is passed.
        //implement code as needed
        return $chart;
    }
}

While this will provide some flexibility, I've been stung more than once using inheritance when injection should be used, and am worried it will lead to no good.  But what would I inject?  I previously suggested injecting a BarChart into a Chart and received a response that doing so is nonsensible.

So, after this long story, how should I implement this?  Thank you

I am creating a system for my students. I teach Photography and I want to do more online integration for my class. As of right now I have a whole system in which the students have their on accounts on my site. Now the challenging part for me.

I need students to upload photos to me, and I will critique them. My questions for this forum a

1. Should I have a line of code that creates a folder per user to upload photos to?
2. Should I have the photos stored in the SQL database?
3. Are there any scripts out there that can be easily adapted for this idea?

These are the specs that come to mind, CPU, RAM, Storage, Bandwith   My question is this, once you know what the point of a website is, whether it is to host videos, design something with an editor, ecommerce, if I ask a costumer "How many people do you expect to be on your site?" Is that a fair question? Or is that arbitrary or even rhetorical like "Duh... the maximum count"   I want to know based on what is being accessed whether it is the photos displayed on page, character count, flash / javascript, whatever... how can I estimate?   This is for assigning VPS's depending on the clients requirement
