Reading a specific line in a textr file from a php var

[auvi1]

Hello everybody  , it’s so nice to have someone to talk to and someone to rely on. I’ve been trying to put together this reader to populate a page on my site where I can read from a specific line in a text file, this text file contains roots to snippets like feeds that I want to put inside a php include statement so that does chunks of text load in a stack order... hope I’m making any sense, I'm trying but I'm not good whit PHP and just don’t seem to make it work... here’s the problem I have:

 

1 loader file:

 

<?PHP

$myVar = file('text.txt');

count($myVar);

include ("$myVar[0]"); // <----- line I want to extract the info from the text.txt file

?>

 

2. text.txt (urls)

 

58expoliciasdetenidosenjuliosaldranfloresesquerro.html

60monrcasnoquieren comer.html

100hombrescomencarnedeunjalo.php

 

The problem I have is that if I want to include a second url using the same method, nothing works.

 

I get a message that says:

 

[function.include]: failed to open stream: Invalid argument in etc. etc.

 

But if I only put one line in the text in the text.txt file and only reference on file in the incudes, it works, if I put 5 url's in the text file it only allows me to reads de last on the list and totally ignores de first 4.

 

Also used this and same result:

 

<?PHP

$myVar = file('2010/text.txt');

$my2Var = count($myVar );

for($x = 0; $x< $my2Var ; $x++)

{

}

include ("$dic2010"."$myVar [2]");

?>

where $lines[2] is the 3th line on the text.txt file... and that’s the online it reads, if I add a 4th line in the text.txt file it will read the 4th line as long as it's the last in the list and called bye $myVar last line.

 

What I want to do is to be able to load multiple includes in different parts of my index.php

 

will you help me? Pleeeeeeease.

Here's a function that I wrote in a class a bit back that uses the file() function to read linebyline a text file into an array, and you can set a limit as to how many lines it returns....

 

/**
         * Read a file out into an array without requiring a handle such as fopen,
         * it uses the file function.
         *
         * @param int $limit Limit the amount of lines you want to be returned in the array
         * @return array An array of elements including each individual line
         */
function lineByLine($limit=0)
{
	// Setup the array of each line, and a count of total lines
	$arrayOfLines = file($this->_workingFile);
	$lineCount = count($arrayOfLines);

	// If the user set a limit on how many lines they want returned
	if ($limit!=0)
	{
		// Loop through and unset the last element of the array
		// until it is to the desired line limit
		for ($i=$lineCount; $i>$limit; $i--)
		{
			unset($arrayOfLines[$i]);
		}
	}

	return $arrayOfLines;
}

I don’t understand how it works... where do I put the txt file link, and what var do I use to put in the include?

Looks nice and clean.

Ok..

 

when you do this...

?PHP
$myVar = file('text.txt');
?>

you are putting the entire file into an array. each element of the array represents one line from the file (presuming each line ends with a \n new line character). because arrays begin counting with 0 (that's a zero), you need to use zero to show the first line. So if you have 3 lines and you wanted to use each of them, you would do this...

 

?PHP
$myVar = file('text.txt');
count($myVar);
echo $myVar[0]; /* this shows the first line */
echo $myVar[1]; /* this shows the second line */?>
echo $myVar[2]; /* this shows the third line */

an easy way to see all of them would be like this...

$myVar = file('text.txt');
$numLines =count($myVar);
$i=0;
while($i<$numLines) {
  echo $myVar[$i] . "<br>"; 

By looping thru the array you could create menu lists, option lists etc etc

 

Make sense?

OK... so I did this:

 

<?PHP

$myVar = file('ligas.txt');

count($myVar);

echo $myVar[0]; /* this shows the first line */

echo $myVar[1]; /* this shows the second line */

echo $myVar[2]; /* this shows the third line */

 

$notaPrima =  $myVar[0];

 

?>

 

<?php

include ("/dic/breves/"."$notaPrima");

?>

 

 

and I get this result in My browser:

 

 

Warning: include (/dic/breves/58expoliciasdetenidosenjuliosaldranfloresesquerro.html ) [function.include]: failed to open stream: No such file or directory in C:\xampp\htdocs\afn65\2010\AutoFiller.php on line 13

 

Warning: include() [function.include]: Failed opening '/dic/breves/58expoliciasdetenidosenjuliosaldranfloresesquerro.html ' for inclusion (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\afn65\2010\AutoFiller.php on line 13

 

The file exists, I can see that include read the variable perfectly because I can see the string, but it jus doesn't open de darn file...

  How does the class work?

Here's  the strange part... If I call the tree at once, I can oly see the las one, as you can see in the image:attached image.

Each array entry includes the new-line character at the end of the string, so you need to use the trim function when you include the file:

<?php
$notaPrima =  trim($myVar[0]);
include ("/dic/breves/$notaPrima");
?>

or you can apply the trim function to the whole array by using array_map

<?php
$myVar = array_map('trim',file('ligas.txt'));
?>
