PHP - Gzip Question
I have just googling in order to find out how to do GZIP so that user can load web page faster. n i found some article which stated that i have to put this script only.
<?php ob_start( 'ob_gzhandler' ); ?> my question is...is it doing the zip? if it is correct where should i put that script, in every page which is needed to be compressed or inside index page only? thanks in advance Similar TutorialsIve gzipped some static html files and want to send it to the browser but not sure how to approach it So i have : http://site.com/cache/file.html (14gb) http://site.com/cache/file.html.gz (1kb) I did this but do i still need a header?? <?php if(file_exists('cache/file.html')){ @readfile("cache/file.html"); } ?> Hi guys, I'll try to be concise. When I use this code (zlib): $xmlFile = 'test.xml'; $data = implode("", file($xmlFile)); $gzdata = gzencode($data, 9); $gzFile = "test.gz"; $fp = fopen($gzFile, "w"); fwrite($fp, $gzdata); fclose($fp); It produces test.gz but when I extract the .gz file I get "test" file (without extension) I need to gzip the xml file (keeping the extension) not only the data (when I extract the gz I should get test.xml back) Is there a way I can do this ? For security reasons I can't use exec() function. Please help! Thanks in advance, Alex hey all now im new to gzip got not much knowledge on it. i was testing my site in seositecheckup and according to the test im asked to compress my html, css and js files and i found this bit of coding on google <?php if(isset($_SERVER['HTTP_ACCEPT_ENCODING']) && substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start('ob_gzhandler'); else ob_start(); ?> i included this file on top of my pages and then it seemed to compress my my file but it seem we need to set header expire on gzip so how could i set expire on it and could someone tell me what exactly is this coding above compressing i mean is it compressing image and all type of files? I have spent all day trying to get any of these functions to work... I have downloaded heaps of expample and NONE! work.. In the case of Zip Archive the CREATE function will not produce a zip file archive to strat with.. Error message says it's created ok... but a search finds no such file. GZip has the same problem. Bzip2 at least creates a blank zip file (17bytes) but I can't add any files to the Bzip2. I have tried on the localhost with dll's installed and on a comercial web server... Nothing gets created... I have read endless examples and documents on the web... None work.. Any help would be much apreciated. I am being sent an XML feed which needs to be downloaded in a 'compressed way'.
The example I have been given is this:
$url = 'http://myurl.com'; $headers[] = "Accept-Encoding: gzip,deflate"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_BINARYTRANSFER, true); $data = curl_exec($ch); but the output I am getting is jargon like this with loads of black diamond question marks:� +T��sƒ���-}#v���]K���������HB�$&G�����Y�����'߷s�,�.4֫'?'���9;*9^��>�j~�ǫ}z|hq�J��Գ".o2)~b���U~I| How to a convert it back into XML? Many thanks Edited by samjsharples, 30 September 2014 - 03:49 PM. Is there a way I can readily stream-process a compressed XML file in PHP? Something like this NON WORKING example: Code: [Select] $reader = new XMLReader(); $reader->open(bzopen($planet_file,"r")); while ($reader->read()) { ... See also http://php.net/manual/en/xmlreader.open.php when in a form, I wish to build a conditional that if the response to a radio button is a value of 2 (female), it will display an input requesting for users maiden name. If not 2 goes to the next input statement. Here is code I was experimenting with: <html> <body> <form action="" name="test" method='POST'> <input type="radio" id="sex" value=1 checked><label>Male</label> <input type="radio" id="sex" value=2><label>Femaleale</label> <?php $result = "value"; if ($result == 2) echo "<input type='int' id='gradYear' size='3' required>"; else echo "Not a female!" ?> <input type="submit" value="GO"> </form> </body> </html> The code passes debug, however, Not a Female is displayed. My question is - Can I do this and if so, what value do I test against id='sex' or value. I tried each one but gave the same results. I realize that $_POST[sex] would be used after the submit button is clicked. But this has me stumped. Thanks for the assis in advance. Just get started with OO in PHP. If I create an object while on one page and then call another page, can I still access that first object, or is it destroyed when the second page is called? For example, if I have on page1.php: Code: [Select] $obj = new $MyObject(); and then call page2.php, is it possible to still access $obj while on that page? I'm considering getting a VPS, but I'm not entirely sure what this would be able the handle. The specs doesn't look that good to me, but my friend swears it will handle running apache/php/mysql handling large websites and databases without a problem. I want to run multiple databases that just store statistics and I'm a bit worried about the RAM and the company doesn't even mention a cpu. Here's the specs: 256MB RAM 300GB HDD 10Mbps unmetered 1 IP Address My friend runs two counter-strike: source servers off his VPS (same stats).. so I'm actually considering this, but it just seems like it's not powerful enough. Oh.. forgot the most important part.. it's only $9. I'm trying to secure my login system as much as possible from SQL injections and other attacks. I know that by using mysql_real_escape_string() you can prevent that and I'm using that on for example the username input, but I would like to know if you hash the password before you send it to the database with MD5, do you still need to use mysql_real_escape_string()? A very quick and simple example: Code: [Select] <?php $un = $_POST['username']; $pass = $_POST['password']; $pass = md5($pass); mysql_query("SELECT * FROM users WHERE password='$pass' AND username='$un'"); ?> If someone wrote a possible SQL query in the password input, wouldn't that be rendered useless as the md5 will hash it before sending it and therefor "hide" it? Or is there any other reason you wouldn't want people to use sertain characters/symbols in their passwords? In php, which function is best used to act something like the sql "LIKE" command? and how would that function be used like? I have been away from PHP for a long time and I was looking over my old scripts. I did PHP OOP at one time and I used a paticular method to connect all my methods up and load them. I have been looking at other peoples code and when I look at my code it does not even feel like OOP, I want to know how to you link all the methods (or is it called functions?) in a class up and return them? I use to do this: Code: [Select] <?php class quickFUNC { function note_pad() { // code for notepad } function quickAdminFunc() { // code for admin func $this->note_pad(); } } $quickFUNC = new quickFUNC; if(isset($_GET['id'])) { $act = $_GET['id']; } else { $act = NULL; } switch ($act) { case 1: //some random code to launch case 1 break; default: $quickFUNC ->quickAdminFunc(); ?> This was my code back in the days, as you can see the notepad was called in the admin function then made the admin function default in the case switch. I looked at all my script and the all are layed out like this :S.. Can I get some help please, thank you. I am trying something simple, creating some horses and making them race using OOP, creating them is easy, how can i find out which one "won" based on the highest total. Here is what i got so far Code: [Select] <?php class Horse { public $strength; public $speed; public $agility; public function create($name,$age,$odds){ $this->name=$name; $this->odds=$odds; $this->strength=(rand(50,200) * $this->odds - $this->age); $this->speed=(rand(100,400) * $this->odds - $this->age); $this->agility=(rand(150,250) * $this->odds - $this->age); $all=array(0=>"$this->strength",1=>"$this->speed",2=>"$this->agility"); echo "<b>$this->name</b> has a strength of <b>$this->strength</b>, a speed of <b>$this->speed</b> and agility at <b>$this->agility</b>. --- <b>".array_sum($all)."</b><br>"; } } $mix=rand(2,6); $a=new Horse; $a->create("Dave", 2, $mix); $a->create("Dude", 3, $mix); $a->create("Evan", 3, $mix); $a->create("Jill", 15, $mix); $a->create("Flex", 10, $mix); ?> I cant figure out a way to find out who had the highest total, i would love to know what i am doing wrong. Major breakthrough. utf8_encode() allows me to view utf-8 characters in the browser. Therefore, my source data file must be ISO-8859-1 encoded text, right? Am I understanding this correctly?
<?php
//mb_internal_encoding("UTF-8");
header('Content-type: text/html; charset=utf-8');
$file = fopen('some_csv_file_created_by_excel.csv', "r");
ob_start();
while (($spec = fgetcsv($file, 100000, ",")) !== FALSE){
echo($spec[0].' '.utf8_encode($spec[0]).'<br>');
}
$string=ob_get_clean();
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>utf</title>
</head>
<body>
<p><?php echo($string);?></p>
</body>
</html>
Edited by NotionCommotion, 11 January 2015 - 08:22 PM. hi php people, I am wondering will if the code below will work when I call $C->getafoo() will I get foo; I keep getting an error at this point return $this->A->a(); saying the method is not there Code: [Select] class A{ public function a(){ return "foo"; } } class B { public $A; function __construct($A) { $this->A = $A; } public function geta(){ return $this->A->a(); } } class C extends B{ public function getafoo(){ return geta(); } } $C = new C(new A()); echo $C->getafoo(); Hello, i am currently working on a project and i have been on google and nothing has helped i am trying to detect characters in the URL so for example XSS if someone typed in the URL:
home.php?=<script>document.cookie();</script>
OR
home.php?=<?php echo file_get_contents("document.txt", "a");
How would i be able to make a kind of firewall to detect this?
and if it does then redirect to another page.
Thanks.
I have an issue with the below code Code: [Select] if ($gtype == "%24L" || $gtype == "$L") The value actually starts with the dollar sign then L, but its being read as a variable that's not assigned so it showing as blank. so the question is how to I get to check and see if the value of gtype actually is $L in a way that it wont read $L as a variable and as a value instead? U guys know in forums how at the top or bottom there links to the "1 2 3 4 5 next" and stuff? and how it loads a database? how would i do that exactly? or explain to me what it could be called. cause me i have no idea :/ Hello. I'm trying to pull information out of an xml file. However I'm a bit lost in getting the actual value. Code: [Select] $url="http://ws.audioscrobbler.com/2.0/?method=artist.getimages&artist=Dr%20Feelgood&limit=1&autocorrect=1&api_key=c107c9b5c09cb5693b6c19409dd984c1"; $xml = simpleXML_load_file($url,"SimpleXMLElement",LIBXML_NOCDATA); $largesquare=$xml->images->sizes->size[2]; Is what I have but its not pulling the information. The above url will give you the link to a set xml file for this example. And I want to get the info for the Code: [Select] <size name="largesquare" width="126" height="126">http://userserve-ak.last.fm/serve/126s/43173899.jpg</size> I'm sure I'm doing something wrong that's a simple fix but I am lost here. In the sizes there are 6 different size options each with different names and I have no idea how to pull the one with the correct name that I need. Thank you to who ever can help me sort this out. Hi, I am looking into a way of adding addons to a class I made.. I thought something like this would work, but not sure how to implement it: Code: [Select] <?php class foo { function foobar($text) { $text = $text . 'b'; return $text; } } class bar extends foo { function foobar($text) { $text = $text . 'c'; return $text; } } $var = new bar(); $var->foobar('a'); // this would then return abc ?> Now i want to be able to call up foo, and it calls the foobar of foo, and the foobar of bar. is that possible? hosh |
