And I'm attempting to pull ONLY the tracking number and reference number (or order #) from this file. I've been able to get rid of the empty lines, get rid of the first few lines I don't need and grab just tracking and reference numbers , but I can' t figure out how to get rid of of the last few lines....here's my code:

Code: [Select]
$arr=file("/home/onest4/public_html/beta/fedex.txt");
$x=1;
    foreach($arr as $str)
    {
      if (trim($str) != '')
      if ($x > 3)

     
      {
        list($tracking,$ordernumber)=explode("  ",$str);

        echo $tracking;
        echo "<br />";
        echo $ordernumber;
 
        echo "<br /><br />";
      }
      else
      {
      $x++;
      continue;
      }
    }
Here's the result:

Anyone help with this?

Thanks!

Hello everyone,

This is my first post and I need a little help. My knowledge of php is limited, so this question may look simple. English isn't my mother tongue, which you have probably noticed already.

So, my problem:
I 've made a a phpscript that adds text to a txt-file, that works perfect, but I also need something to delete some parts of the file.


part of my html-code: Code: [Select]
<form method="POST" action="verwijderscript.php">
<table class="noborder">
<tr><td class="noborder">

<input type="text" id="verwijdertitel" name="verwijdertitel" size="40">
<input type="submit" name="s1" value="Verwijder Bericht" />

</td></tr>
</table>
</form>
part of my txt-file:
Code: [Select]
<div  id="Testtitel">
<span class="subtitel">Testtitel</span>
<span class="rechts">Gepost op 15/03/2011</span>
<br>
<img class="nieuws" src="image.gif"><br>
texttexttexttexttext<br>
texttexttext<br>
text

<div class="streep"></div>
</div id="Testtitel">

<div  id="Testtitel2">
<span class="subtitel">Testtitel2</span>
<span class="rechts">Gepost op 15/03/2011</span>
<br>
<img class="nieuws" src="image2.gif"><br>
texttexttexttexttext<br>
texttexttext<br>
text

<div class="streep"></div>
</div id="Testtitel2">
part of my php-code:
Code: [Select]
<?php

$titel = $_POST['verwijdertitel'];
$oud = file_get_contents("data.txt");
$data = fopen("data.txt", "w+");
$nieuw =  str_replace("id=\""$titel, "id=\"hidden", $oud);


fwrite($data, "$nieuw");
fclose($data);
            header("refresh:0;url=http://www.test.com");

?>

css:
Code: [Select]
#hidden{display:none;}
Problem: parse error line 6 of php-file
And I don't think this works if the error is solved. I don't have a MySQL database, that's why I use a txt files.

What I try to do is to hide the div, it would be better to delete it, but than I need to work with regex, I guess 

I want to add text to a file, getting it printed out in index.php and later want to edit/delete per row. I give codes page wise. first the form to take data:
add.php:
Code: [Select]
<?php
?>
<form method="post" action="add_data.php">
<fieldset>
<legend>Student List</legend>
Name : <input type="text" name="uname" /><br>
Content : <input type="text" name="age" />
<br>
<input type="submit" name="submit" value="send" />
</fieldset>
</form>
Next adding text to a file: add_data.php:
Code: [Select]
<?php
$id = 1;
if (file_exists("data.txt"))
{
$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);
foreach ($str_arr as $rec)
{
if ($rec)
{
$id++;
}
}
}

$mode = (file_exists("data.txt"))? "a" : "w";

$fp = fopen("data.txt", $mode);
$line = $id . "--" . $_POST['uname'] . "--" . $_POST['age'] . "|";
$res = fwrite($fp, $line);
fclose($fp);

header("location:index.php");


?>In the index.php, I'd like to fetch data and edit them per row:
Code: [Select]
<?php
$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);
echo "<table border='1'>";
echo "<tr><td>ID</td><td>Name</td><td>Age</td><td>Option</td></tr>";

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
echo "<tr>";
foreach ($rec_arr as $col)
{
echo "<td>$col</td>";
}
print "<td><a href=\"edit.php?id=$id\">Edit</a>/<a href=\"delete.php?id=$id\">Delete</a></td></tr>";
}
}
echo "</table>";

echo "<a href=\"add.php\">Add Data</a>";

?>


Next I want to Edit per row: edit.php:
Code: [Select]
<?php

$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];
if ($id == $_REQUEST["id"])
{
echo "<form action='edit_data.php' method='post'>";
echo "Name :<input type='text' name='uname' value='$name' /><br>";
echo "Age: <input type='text' name='age' value=$age /><br>";
echo "<input type='hidden' name='uid' value=$id />";
echo "<input type='submit' value='Edit'>";
echo "</form>";
}
}
}


?>
From edit.php to edit_data.php where I practically try to edit per row:
Code: [Select]
<?php

$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];

if ($id == $_POST['uid'])
{
$new_str = $id . "--" . $_POST['uname'] . "--" . $_POST['age'] . "|";
}
else 
{
$new_str = $id . "--" . $name . "--" . $age . "|"; 
}
}
}

fclose($fp);

$fp = fopen("data.txt", 'w');
fwrite($fp, $new_str);
fclose($fp);


?>
The mechanism is simple. Taking datas from a form, explode them to an array and get them into col/row pattern to edit and delete them. But my problem is when I want to edit in index.php page, specially in this part:
Code: [Select]
print "<td><a href=\"edit.php?id=$id\">Edit</a>
It says, undefined index. But I try to catch this $id in the edit.php page, in this manner, as you see in my code:
Code: [Select]
foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];
if ($id == $_REQUEST["id"])
{
echo "<form action='edit_data.php' method='post'>";
echo "Name :<input type='text' name='uname' value='$name' /><br>";
echo "Age: <input type='text' name='age' value=$age /><br>";
echo "<input type='hidden' name='uid' value=$id />";
echo "<input type='submit' value='Edit'>";
echo "</form>";
}
}
}
Have I done any mistake here? If anyone points out, I'll be obliged.

My current code (which works):

Code: [Select]
<?php

$body = explode("\n", $body);
$body = array_slice($body, 3);
$body = implode("\n", $body);

?>

Is there a better way of doing this, so I dont have to explode and implode an array just to accomplish this?

Dear all,
I want to remove all lines less than 3 words longs so I can stuff the rest into a db.
Can somebody help me?
Thank you in advance

This topic has been moved to Editor Help (Dreamweaver, Zend, etc).

 Thanks ahead of time, I have been working this all week end but get lost....
    a.  I want to insert all the lines from file1.txt into file2.txt .
    b.  I want the all lines in file1.txt to be inserted in file2.txt starting at "<image>"   tag label in file2.txt.
    c. I would like to overwrite all lines that start with the "<image>" tag in file2.txt with the insert (text in file1.txt contains <image> tag also).
 
 file2.txt has lines above  and below the insert point <image>.   The insert text (file1.txt) could be as many as twenty lines (records) all/each beginning with the<image>tag.
Here is what I have done so far.
<?
$key = '<image>';  //a text tag in $file1  and $file2

//copy file 
$file = "file1.txt";
$file2= 'file2.txt";
$newfile = "filetemp.txt";
copy($file, $newfile) or exit("could not copy $file");

//load file array
 $fc = fopen ($file, "r");
 while (!feof ($fc)) 
 {
    $buffer = fgets($fc, 4096);
    $lines[] = $buffer;
 }

fclose ($fc);

//open same file and use "w" to clear file  ,not sure this is needed
$f=fopen($newfile,"w") or die("$file did not open");

/* uncomment to debug
print_r($lines);
print "<br>\n";
*/

//loop through array 'foreach
foreach($lines as $line)
{
       fwrite($f,$line); //rewrite $line in file     
    if (strstr($line,$key)){ //find $key in each line
    fwrite($f,$newline."\n");
    } //rewrite $line in file 
}
fclose($f);

copy($newfile, $file2) or exit("could not copy $newfile");
?>


Again thanks ahead of time,  I just keep losing the flow,  old I guess.

If I want to read in and process a CSV of a 1000 lines how easy is it to do without a database?

By process, I mean read in the data and do simple manipulations + compare each line with a line from another file, that maybe have 50 lines

I was just concerned that I might start hogging the CPU and memory of the server trying to process 1000 lines of data
It's VERY important that I can do WITHOUT a database

I'd only consider a database if it proves that not using will take too much CPU and memory

I've only just began considering making the application - can't give full details - as I've got to figure them out myself!

Any general advice would be great

Thanks

I have a form that is processed using PHP (post method) and there is a textarea people will enter text into.
After processing, the text is displayed to the user.  However, if the user did a Carriage Return (i.e. hit Enter) when they originally entered the text, that text does NOT show on a new line when displayed later.

For example, if they type this into the text area...

"Hello there (they hit Enter here)
How are you (they hit Enter here)
Good I hope"

It will display like this, all on one line:

"Hello there How are you Good I hope"

In other words, it doesn't seem to remember that Enter was hit.

Is there some way to "preserve" the fact that someone hit the "Enter" key, so that when text is displayed later, it will show the text on a new line if the user in fact hit "Enter" when originally typing it.

I am probably not using the right terms in the right spots (i.e. newline, carriage return, enter, etc) but I think you get the picture

Let me know if anyone knows how to do this.

Thanks!

Hi All,

If someone types in my textarea without any hard returns, it echos the entire text on a single line, which expands my site very very far and screws up the layout.

how can I echo the text but limit the number of characters per line before I insert my own line break?

The code is just:

Code: [Select]
echo $message;

Hey guy, I really need your help with this.

I have Input from a text area, in this format:

a
b
c
d

e
f
g

12
34


435

124


What I need do to is to output only a certain line from every block of text, every block is divided by one or more empty lines.
I have done this:


$input = $_POST["input"];
$lines = explode("\r",$input);
$num = count($lines);
$line_to_extract = $_POST['line_to_extract'];

for($i=0;$i<$num;$i++) 
{

if($i == $line_to_extract)

{

echo 'Line '.$i.': '.$lines[$i].'<br />';

}
}
 

What I need to do is to detect the empty line so I can keep track of the line to extract.
