Read all files from folder and handle the lines separately

[khosh]

Hi,

 

I'm quite unfamiliar with php. I'm trying to read all files in a directory, open them and handle the lines in the files separately.

 

The files to be read might look like this:

1 Product code:
2 FP50
3
4 Description:
5 Pine 50x100mm
6
7 Price:
8 3.5

 

I've gotten as far as learning that

 

$file = file(filename);
echo $file[0];

 

displays the first line of a file, and $file[1] the second and so on...

 

What I want to do is add several info files in one folder. I then want to read them all and display them in the same way with one short piece of code that runs through everything and displays the info where I want it, for example:

 

<table>
<tr>
<td><?php echo $file[1]; ?></td>
<td><?php echo $file[4]; ?></td>
<td><?php echo $file[7]; ?></td>
</tr>
</table>

 

This way I only have to add a new file to the folder and the script displays the information in the table. I know it's possible, but I just can't get my head around it.

 

Any help is greatly appreciated!

look at using foreach http://php.net/foreach

foreach($file as $line)
     echo $line . "
\n";

Thanks for the tip. I thought it might have to do with that. Still, I can't get it to work.

 

I found this code to read through the folder and collect all the filenames:

$handle=opendir($path);
while (($file = readdir($handle))!==false) {
if ($file != '.' && $file != '..')
echo $file;	
}
closedir($handle);

 

It outputs a list of the files in the folder.

 

I tried to replace the "echo $file;" with this code:

	foreach($file as $line)
$content = fopen("$path/$line", "r");
echo $content;

 

but now I get "Warning: Invalid argument supplied for foreach() in ... on line..."

The foreach doesn't seem to work and I'm not sure I used the fopen command correctly either.

$handle=opendir($path);
while (($file = readdir($handle))!==false) {
if ($file != '.' && $file != '..') {
	$content = file_get_contents("$path/$line");
	echo $content;
}
}
closedir($handle);

Ok, now I got it to read all the info from the files when I changed the

$content = file_get_contents("$path/$line");

to

$content = file_get_contents("$path/$file");

 

Now it displays all info from the files. How do I get it to read specific line numbers from each file and not the whole file? When simply using "echo $content[0]" it only shows the first letter/sign from each file.

Got it! I just used explode with \n as separator.

 

Huge victory for a newbie!

Thanks for all the help, I'll ask more if I encounter other problems... after trying to solve them myself of course!

glob() is simpler:

 

<?php
$path = 'sampledir';
$files = glob("$path/*");
foreach ($files as $file) {
$lines = file($file);
echo "<table>
\t<tr>
\t\t<td>{$lines[1]}</td>
\t\t<td>{$lines[4]}</td>
\t\t<td>{$lines[7]}</td>
\t</tr>
</table>
";
}
?>

So it seems. Short and handy. Thank you!
