PHP - [starting To Learn Php And Html] Need Help Using Php!

I can't for the life of me understand how to perform this so I need some professional help here.

I have a large array that contains some garbage every Nth and Nth + 1 element that needs to go away. array_filter doesn't work with keys but anyhow, i wouldn't know how to design the function.

My keys are numeric, starting from 0. The keys I want to remove are part of this sequence: 8, 9, 18, 19, 28, 29 ...

Can someone help me design a generic function to remove these keys?

function filter_keys($array, $n, $offset) {}

$new_array = filter_keys($array, 10, 8 );

I would maybe have to run this function twice, once for 8 offset and once for 9 offset.

Hello,

I'm a newbie and would like to learn PHP. I have some HTML and CSS skills, but would very much like to upgrade them to PHP.

How can I do that? What materials do you suggest I read?...

Thanks,

Ok figured I'd go out and try to write me something for my site that I want and can't seem to be able to find what I want...sooooooooooo   I'm trying to create an NFL score 'ticker' and so far I've gotten as far as fetching the xml.. that part works LOL   I have been sitting here for a few hours trying to figure out how to do a foreach statement that works... I've hit a brick wall because I just can't seem to figure it out...   I have even tried a few I've found in other places but no go...   Here is what I have so far:

<?php

$url="http://www.nfl.com/liveupdate/scorestrip/postseason/ss.xml";
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);    // get the url contents

$data = curl_exec($ch); // execute curl request
curl_close($ch);

$xml = simplexml_load_string($data);
print_r($xml);  //just keeping this here so I can see it for now

?>

I know that part is working as you can see I left the print_r in it temp so I can still see I"m getting what I need...   Again the problem is I'm not getting a functional foreach that I can get to work.. I either get nothing back or an error of some kind and trust me I've tried as many as I could find LOL

My object is returning this and that's great... but my foreach skills need a TON of work apparently...    I think I've looked at it too much and too long... some suggestions would be VERY much appreciated...  Probably a bit big of a project to try on my first real attempt but I just went through the foreach in my tutorial but it's just not working....   What I'm looking to do is output the d, t, htn, vtn, hs, vs...    I was trying to just get it to show just one of those but no go...   Thanks everyone!!

This script with minor changes came from a tutorial. I did a var dump and get a NULL result.  Can anyone tell me why?

Hello everyone - I have picked dup a book on php and SQL and have been quaking through it. I have come across a problem with a foreach statement that I can not resolve.

Any help and advice is greatly appreciated!

 

<?php

    try {
        $pdo = new PDO('mysql:host=localhost;dbname=ijdb; charset=utf8', 
            'ijdbuser', 'mypassword');
        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $sql = 'SELECT `joketext` FROM `joke`';
        $result = $pdo->query($sql);
        while ($row = $result->fetch()) {
            $jokes[] = $row['joketext'];
        }
    } 
    catch (PDOException $e) {
        $output = 'Unable to connect to the database server: ' .
        $e->getMessage() . ' in ' .
        $e->getFile() . ':' . $e->getLine();
    }
include  __DIR__ . '/../templates/jokes.html.php';

and the other file

 

<!doctype html>
<html>
    <head>
        <meta charset="utf-8">
        <title>List of jokes</title>
    </head>
    <body>
        <?php if (isset($error)): ?>
        <p>
            <?php echo $error; ?>
        </p>
        <?php else: ?>
        <?php foreach($jokes as $joke ): ?>
        <blockquote>
            <p>
            <?php echo htmlspecialchars($joke, ENT_QUOTES, 'UTF-8') ?>
            </p>
        </blockquote>
        <?php endforeach; ?>
        <?php endif; ?>
    </body>
</html>

 

I am wondering whether there is a way to do a foreach loop for an array, without starting at index[0].  Say, for example, I wanted to start displaying the contents of a 20 item array starting at index 5, what is the best way to do it?

I know of this way, but it seems too crude (ie. there has to be a better way):

$count = 0;

foreach($array as $item)
  {
  if ($count > 5)
    {echo $item;}
  $count++;
  }

Any other ideas??

Hey guys just thought I'd introduce myself as it's a polite thing to do. My name is Nick I am currently a front end developer and love learning new technologies so it looks like PHP is my next step.   I hope to learn and give whatever knowledge I can back

Why do I get the following results (specifically the second example)?  I thought it would be documented under https://www.php.net/manual/en/language.types.string.php, however, the word "ampersand" doesn't appear.  Also, looked at logical operators, but found nothing.  Thanks

function test(string $string){
    printf('%s %s %s 0'.PHP_EOL, gettype($string), $string, $string==0?'==':'!=');
}

test('123');
test('@123');
test('1@23');
test('123@');

Quote

string 123 != 0
string @123 == 0
string 1@23 != 0
string 123@ != 0

 

good day dear PHPFreaks - hello  to everybody.


i want to create a link parser. i have choosen to do it with Curl. I have some lines together now. Love to hear  your review... Since i am new to programming i love to get some hints from experienced devs.

Here some details: well since we have several hundred of resultpages  derived from this one: http://www.educa.ch/dyn/79362.asp?action=search

Note: i want to itterate over the resultpages - with a loop.

http://www.educa.ch/dyn/79376.asp?id=1568
http://www.educa.ch/dyn/79376.asp?id=2149


i take this loop:

for($i=1;$i<=$match[1];$i++)
{
  $url = "http://www.example.com/page?page={$i}";
  // access new sub-page, extract necessary data
}


what do you think? What about the Loop over the target-Urls?

BTW: you see - there will be some pages empty. Note - the empty pages should be thrown away. I do not want to store "empty" stuff.

well this is what i want to. And now i need to have a good parser-script.

Note:  this is a tree-part-job:

1. fetching the sub-pages
2. parsing them
3. storing the data in a mysql-db

Well - the problem - some of the above mentioned pages are empty. so i need to find a solution to
leave them aside - unless i do not want to populate my mysql-db with too much infos..

Btw- parsing should be a part that can be done with DomDocument - What do you think? I need to combine the first part with tthe second - can you give me some starting points and hints to get this.

The fetching-job should be done with CuRL - and to process the data into a DomDocument-Parser-Job.
No Problem he But how  to do the DOM-Document-Job ...

i have installed FireBug into  the FireFox...

now i have the Xpaths for the sites:

Hi all,

I am an intermediate PHP Programmer, but I'm now stuck with getting any further. I am currently developing a CMS with a few people. However, I wish to put that aside for a month or so and learn PHP a bit better.

Can anyone suggest a fairly "easy" project for me to do to learn a bit more about PHP?

Best Regards,
DM

I am trying to find a tutorial on how to perform a depth first search. I've seen pseudocodes and sources in other languages, but I just can't implement it in PHP no matter what I try. Can anyone show me how or where I can read up on it or how to do it?

Hello Guys...
I'm new to php & mySQL... I need help... Need something to know... please help me...
I'm using ubuntu 11.10, Aptana Studio 3, xampp 1.7.7.
Also i'm using windows 7, notepad++ & wamp.
When I visit "localhost" on my firefox. I saw a xampp or wamp welcome page. The name of the file is "index.php".

1. I need to know can I delete this file ? Bcoz i'm working on another file but it's the same file name.

2. When I upload my site on host like hostgator. How do i edit my live site? And preview it.

3. How do i store my post on database ? Like fb status update, blogger post or forum post

I wanna write a site that i can post something without using html <p></p>. The main problem when i need to post something then everytime I need to edit the source code. Example:<p>some text here</p>.

I don't wanna edit source everytime.

Another Ques: Is Aptana Studio and notepad++ enough to write a site or I need another tool ?

Any book suggestion ?

please guys help me i'm new to php & mySQL..
