PHP - Moved: Opening More Then One Tab

Hey all,

I'm just having a problem with this code.. the local server says it has an error on a particular line that will be pointed out in the coding section.
Code: [Select]


<?php
$hd = fopen('content.txt', 'r');
$line = fgets($hd);
$content = array();

while($line)
{
$word = explode(',', $line);
$content [$word[0]] => array('img_path' => $word[1], 'description' => $word[2], 'price' => $word[3]); 

// the error message is indicating this line is broken!! Is it because of an equal sign missing? I tried putting an equal sign, but still it doesn't run.

$line = fgets($hd);
}
fclose($hd);

?>

Your help is greatly needed..

Hi there,

I am new to PHP and trying to put my learning together as I progress. Here's the problem: I would like to open HTML file after a certain condition is met. I tried to fopen() but it gave an empty page.

Here's the code:
Code: [Select]
<?php
$shape = $_POST['shape'];
if($shape=='Triangle') {
fopen('ogc_show_triangle.php', 'r');
}
else {
echo "Select a shape.";
}
?>
Thanks in advance! ^_^

Hi.  I am working with some rather large files.  Sometimes I am just opening a file and trying to find an entry on a single line.  Sometimes I am opening a file and working on each line.   Whats the most efficient way to work with a large file?   If I open a file, and place all lines into an array, I will use a lot of memory.   If I open a file, and work on it line by line, I should use much less memory, but will the process take longer?   Whats most efficient?   I have underlined my main question above.   Thanks :-)  

if (!file_exists('../images/flags/imNum.txt')) {

$file1 = fopen('../images/flags/imNum.txt','c');

fclose($file1);
}

why won't that work =\

it makes no sense to me

Hi everyone   As a new member I am impressed with the response and how helpful folk are, thanks in advance  . I am trying to figure out if I can open a html modal window as soon as a link is clicked.   e.g.   web url link (click this modal window opens in the centre of screen with the results of the query) I don't want to show any info in the toolbar just results of the query ? can this be possible, an example would be handy to see the mechanics of it, are there any browser issues with this ?   thanks again ...singhy

Warning: include(): Failed opening 'lang/en.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/name/public_html/db/config.php on line 13

What does the for inclusion mean.   Line 13:

include 'lang/'.$_SESSION['default_lang'].'.php';

Thank you.

There are no opening and closing tags in the code example of the file PostsController.php in this tutorial: http://book.cakephp....g/part-two.html     Should I always use opening and closing PHP tags throughout with CakePHP?
 

Hello, everyone. I have code that effectively calls a PHP page with AJAX  (no JQuery).  The PHP responds fine with an echo.  Here is the javaScript that calls the PHP so refreshing the page doesn't need to be done.

 

function deleteCategory()
{
	var e= document.getElementById("dropDown1");
	var var1 = e.options[e.selectedIndex].text;
	var xmlhttp = new XMLHttpRequest();
	xmlhttp.onreadystatechange = alerta() {
	if (this.readyState == 4 && this.status == 200) {
		
			document.getElementById("insert").innerHTML = xmlhttp.responseText;
		}
	};
	
	xmlhttp.open("GET", "deleteRow.php?q=" + var1 , true);
	xmlhttp.send();
 }

How do I call a PHP function on the same page while preserving the above AJAX.

 

Sincerely,

Joshua

The code is for generated a home page with two div's: 'left_menu' and 'right_menu', where I want to navigate with the links from left_menu should display the content on the right_menu.

I have two links (reports and roles) on the left_menu and two tabs (tab1 and tab2) on the right_menu.

 1. When I click on reports, it should open the tab1 and clicking on
    users should open the tab2.
 2. When I launch home.php, the first item(reports) should be opened by
    default and the tab1 accordingly.

Here is the my code I tried, when I click the roles on left_menu, it is opening the default one i.e. tab1 and the left_menu isn't opened by default.

home.php

Hi guys,

I know that you can open web page with $handle = fopen("http://www.example.com/", "r");
but i am wondering is there a way to pass POST vars when doing so, or there is another method that can that like you do it with ajax.

I have mvc application that i want to test. I am using CodeIgniter framework so i want to call my controllers
with POST values. Every controller method returns data holder object that holds the data of operation whether is successful or not. Also every method inside controller can be called with parameter input or with post input. If you omit the parameters when calling controller method than he will try to load that parameters from post and that is why i want to pass POST vars with php when calling controller for example i want to call:

fopen("http://localhost/MyAppFolder/index.php/controller/method");

but i want to pass it some POST vars if that is possible

Thanks.

Code: [Select]
<html>
<head>
<title>Testing</title>
</head>

<body>
<?php
$config = parse_ini_file("config.ini",1);
$email = $config['Email'];
$host = $config['Host'];


print_r ($host);

 $ch = curl_init();

 curl_setopt($ch, CURLOPT_URL, $host);


 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$contents = curl_exec ($ch);


$fp = fopen($host.'.txt','w+');
$fw = fwrite($fp, $contents);
curl_close ($ch);
fclose($fp);

?>

</body>
</html>
Ok, I am having a problem here.
I have an automation script I am trying to make, but I hit a road block.

I need to open up multiple URL's from using an array of URL's stored in my config.ini file.
It looks like this:

Code: [Select]
Config.ini
Host[] = www.websitea.com
Host[] = www.websiteb.com
Host[] = www.websitec.com
Host[] = www.websited.com
I want to use curl_setopt to open up each one of the urls stored in $host.

If I use...
  Code: [Select]
print_r ($host);

...I get this output:

Code: [Select]
Array ( [0] => www.websitea.com [1] => www.websiteb.com [2] => www.websitec.com [3] => www.websited.com )
Now, I need to take those websites in the array and open each one of them using curl_unit.

I tried doing this... 
Code: [Select]
curl_setopt($ch, CURLOPT_URL, $host);
Then
Code: [Select]
$fp = fopen($host.'.txt','w+');

But I knew that wouldnt work.

Basically, I need to open up all of the pages listed in the .ini file and save the HTML Content of those pages to their own text file, that's named after the URL.
I figured I could open an array of URLS from my INI and write each one to their own text file.


Example:
websitea.com.txt (HTML Content from www.websitea.com)
websiteb.com.txt (HTML Content from www.websiteb.com)
websitec.com.txt (HTML Content from www.websitec.com)
websited.com.txt (HTML Content from www.websited.com)

I have the following code:

$fp = fopen(“path_to_file”, ‘a’);
flock($fp, LOCK_EX);
fwrite($fp, $string);
flock($fp, LOCK_UN);  
fclose($fp);

If I try to lock the file in two different places at the same time, this will cause a race condition. How can I prevent this? I know in Java, for example, it has a concurrent library which contains reentrant lock, which basically tries to get the lock and if can't waits. What can I do in PHP?
