PHP - Delete Lines In File ( Between Given 2 Strings )

 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.

I need to read all the rows from a text file between two specific lines into an array where I can process them. I then need to do the same thing again until the end of the file. The file is too large to read the entire file into an array. The number of rows that are between the key lines are variable.

This is what I have so far to read the first set of rows into the array but it is only reading the first row when in fact in this case there are 15. Any pointers as to where I am going wrong please?

if ($_POST['srch']=="Import") {
                            //open file for reading
                            $family_rec=[];
                            $file_handle = fopen($fn, "r");
                            if(!$file_handle){echo "Could not open file";}
                            while(!feof($file_handle)) {
                                $line = fgets($file_handle);
                                if ((strpos($line, "0 @") !== false) && (strpos($line, "FAM") !== false)) {
                                    $famref = explode("@", $line);
                                    $line = fgets($file_handle);
                                    //echo $line."<br>";
                                    do{
                                        $family_rec[]=$line;
                                        $line = fgets($file_handle);
                                        //echo $line."<br>";
                                    }
                                    while((strpos($line, "0 @") !== false) && (strpos($line, "FAM") !== false));
                                    print_r($family_rec);
                                }//end of family

                            }//end of while not eof

                        }//end of import

 

I have a .txt file containing hundreds of lines of Names (e.g. Brad, Jennifer, etc.)
What coding can I use to only echo the first 20?

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

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:

Hi,

I have built a captcha system that saves the captcha to a temp folder with the file name captcha_CURRENT_TIME_STAMP where CURRENT_TIME_STAMP is the unix time.

I want to delete images older than 5mins old by reading the time stamp on the file name. My question is this:

How can i loop through the image folder and read the time stamps on the file name and delete all images older than 5mins?

Thanks

hi friends!!
in php > 5 i use "session_regenerate_id(TRUE)" in order to generate a new session file and delete old one.
In php 4.x the TRUE parameter doesn't exist: old files will be accumulated until the garbage collector will cleans all.
How can I delete old session file in php 4.x having regenerated the new one?

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 

Hello Mates,
         I am in need of help. I have a Flat File News Script. I am not sure how to build the Delete script..
i am not knew to PHP but kinda new to Flat File Database.. the reason why im using FFD is because my service doesn't allow mysql on the cheaper priced web pages.. i have 4 fields     ID || user_name || title || message

i want it to check the id because it will be in the url like  http://webpage.com/delete_news.php?id=3  and the id 3 and the other fields in id 3 is deleted.

Thank you

I've created a demo page for my CMS, and I want to delete itself and make a fresh content install.

I got the delete part figured out, but what about uploading fresh content files? (only a few text files).

Here's the delete part:

Code: [Select]
<?php
$expiretime=720; // minutes (in how many minutes it deletes the files)

$tmpFolder="tmp/"; // where to delete the files - be careful with this.
$fileTypes="*.*";

foreach (glob($tmpFolder . $fileTypes) as $Filename) {

$FileCreationTime = filectime($Filename);
$FileAge = time() - $FileCreationTime; 

if ($FileAge > ($expiretime * 60)){

//deleting files:
unlink($Filename);
}

}
?>

Hello, I'm requesting your help here cause I'm really confused.
I'm looking for deleting entries when an image doesn't load on my links test.

I got all my links in a .txt file like this :
links.txt =
Code: [Select]
<div class="gallery">
 <a href="http://www.website.com/page">
  <img src="http://tc16.easythumbhost.com/image.jpg" onerror="ImgError(this)"/>
 </a>
</div>
#enddiv
the "onerror" code in img src sends an "Image Missing" pic.
What I'd want is to change the "onerror" function to open a php script which deletes all the lines of the div.
This is the script I use to show the links on my page :
Code: [Select]
$links = "links.txt";
 $fd = fopen ($links, "r");
 $content = fread ($fd,filesize ($links));
 fclose ($fd);
 $delimiter = "#enddiv";
 $splitcontent = explode($delimiter, $content);
 $output = array_slice($splitcontent, 0,100);

 foreach ( $output as $divs )
{
 echo "$divs";
}
I've searched hours and tried lots of codes before posting
Help would be very appreciated. Thanks.
