Ooo oga dhtml18... You should start researching o because op specifically mentioned you.

Did you not read the place I conceded defeat above? this basic PHP don big pass me (am even thinking of retirement as i don become olodo).

Truthfully, you cannot get a file's contents unless you open the file. Additionally, you cannot open a file without first loading it into memory. This part has little to nothing to do with programming, and everything to do with how computers are designed. Whenever you tell the computer that you want to use a certain file on your hard disk, the computer takes your command, locates the file and makes it available for you in RAM. Even the operating system that manages your file request is running in RAM. It's simply how computers work.
And on the programming side, it is the functions like fopen, file and file_get_contents that allow us to manage our file requests. In simple terms, that is how the implementation works. Even if you used another programming language and they had a different function called whatever, it would still make the same request to the OS as fopen, file and etc.
Now, if your only objective is to get the file contents as an array, without using any function with "file" in it, then I think I understand. That is something different altogether. It can easily be done using fopen, fgetcsv and fclose (the word "file" is not written out in these functions).

<?php

    $names = []; // declare here for scope purposes

    // make sure file can be accessed
    if(($file = fopen( "names.txt", "r" )) !== FALSE) {

        // read each line in the file
        // you have the names delimited by semilcolon, so use that in the function
        while(($line = fgetcsv($file, ";" )) !== FALSE) {

            // put the contents into $names array
            $names[] = array($line[0], $line[1]);

        }

        // done with the file, so we can now close it
        fclose($file);

    }

    // print the names in the $names array
    print_r($names);

    // Should Give you
    /***
     * Array (
     *     [0] => Array (
     *         [0] => john
     *         [1] => jack
     *     )
     *     [1] => Array (

     *          [1] => jill
     *     )
     *     [2] => Array (
     *         [0] => alex
     *         [1] => wellington
     *     )
     * )   
     ***/
?>

You don fail already, did you not see the place above that the OP said he does not want to use stuffs like fopen, file_get_contents, file and their families.

paranorman:
i know this one too bro. Done it.
But's still uses an extended file() function.
I am talking....:
fopen
while (!feof..)
fgets
..i used these, but the code is unnessarily long and uses lots of manipulations and overwrites the whole file.
You can do better.

It seems he actually want us to do a freaking miracle like this dude:

Nmeri17:
All of you up there are big Olodos in fact, you all should collectively get a mention whenever "Olodo" is typed on nairaland that said, we get straight to business. OP, here is the code variant you have sought all your life!

<?php
include " paranorman_miracle_working_class.inc";

$cached_file = PMWC::para_read(PMWC::para_open ("names.txt", PMWC::size("names.txt", "r+";

$swap_string = PMWC::replace ("nmeri17 is a god", "Alex", $cached_file);

$case_closed = PMWC::para_read($swap_string, "x";

 if ($case_closed) {
echo "paranorman is a nice monicker" . "\ ";
}
?>

My guy, I read his posts five times over just to make sure I understood well enough, and concluded that he may not have known the right words to use to describe his situation. From how I understand it now, he doesn't want to use functions that have the word "file" in them. I take it that he meant it literally (as in, if the function has the word "file", then he doesn't want to use it). So, I stuck with the f-type functions (they don't have the word "file" in them). Now, if he comes around and says that is not what he is looking for, then I will be at a loss. There's just no other way around this save for juju and there is no juju in computer programming.

Hmn, I read the post like 20 times at least, and yet I still feel like monkey-banana, this OP has made a monkey-out-of-me!

I am still waiting o, not going to sleep o.

See why basic communication skills are important. The other day a full grown papa wandered into this section and farted some of foulest english this room has seen in a long time. He stuck to his guns and other programmers stood by him too.
Now, see miscommunication keeping some1 up all night, spawning multiple posts all to get at the gist of what the op was trying to say! (excess typing , excess time, excess brain cycles constitutes wasted resources).

And i am still waiting. . . .

<?php
while (waiting==true) {
continue;
}

this is twice as nice than rice!

Thank goodness you understood o.

As a rookie, I never see this kain syntaxes before o..

boss, I not implying that you do not use the fopen, fgets, fputs, fwrite functions, what I mean is that you do not use functions with 'file' in its syntax; like readfile(), file_get_contents, file(), e.t.c.

you are correct...!
So, you haven't replaced the string though..

dhtml18:
And i am still waiting. . . .

invalid argument supplied on line 2..

Hehehehe

It is a miraculous syntax in case you failed to realize it

If that is the case, use fopen in the code i supplied earlier - i am not going to write any more codes on this thread anymore for sanity reasons.

paranorman:

Hehehehe

We await your solution. . . .

paranorman:

Replacement can easily occur in the while loop, just by adding an if condition.

<?php

    while(($line = fgetcsv($file, ";" )) !== FALSE) {

        // check for "alex" in $line[0], since that should be its index
        if(strcmp("alex", $line[0]) == 0) {

             // once found, replace "alex" with "whatever you want"
             $line[0] = "whatever you want";

        }

        // put the contents into $names array
        $names[] = array($line[0], $line[1]);

    }

    // print the names in the $names array
    print_r($names);

thanks for your time on this thread, you guys were really helpful.

paranorman:
thanks for your time on this thread, you guys were really helpful.

You need to submit the trivial/basic code o, otherwise, i go para for you seriously o.

paranorman:
thanks for your time on this thread, you guys were really helpful.

You should be aware that the solution provided will replace all instances of "alex" at index 0. So if you only want to replace a certain "alex" or do different replacements at certain indexes, you will have to add to the if-statement or create a decision tree of some kind.

bros, which kain solution you dey wait for na? rookie like me wey no understand anything?! That was why I laid the question all bear here, though it was kinda ambiguous at first; you guys pulled it through.

Here is my own nonsense version of the code jare, I bet you and ChinenyeN will understand me after checking it out - it's kinda unnecessarily long jare, that was why I was looking for a 'shortcut':

$file = "names.txt";
  $fp = fopen($file, "r+";
  $output = "";
  while (!feof($fp)) {
    $line = fgets($fp);
    $output[] = $line;
  } //end while loop
  
  $newOutput = "";
  foreach ($output as $lineData) {
    $lineArray = explode(";", $lineData);
    $newLineArray = "";
    foreach ($lineArray as $name) {
      $name = trim($name);
      $newLineArray[] = $name;
    } //end foreach
    $newOutput[] = $newLineArray;
  } //end for loop
  
  $textFile = "";
  foreach ($newOutput as $data) {
    $newData = "";
    foreach ($data as $txt) {
      if ($txt == "john"{
        $txt = str_replace($txt, "johnson", $txt);
      } //end if
      if ($txt == $data[sizeof($data) - 1]) {
        $txt = $txt."\n";
      } else {
        $txt = $txt.";";
      }
      $newData[] = $txt;
    }
    $textFile[] = $newData;
  } //end loop
  
  $updateOuput = "";
  foreach ($textFile as $strng) {
    $finalText = implode("", $strng);
    $updateOuput .= $finalText;
  } //end if
 
  fclose($fp);
  $newFp = fopen($file, "w";
  fwrite($newFp, $updateOuput);
  fclose($newFp);
  //var_dump($updateOutput);

Paranorman, I would say that you did good, being a rookie. I always try to remind people that programming is about critical thinking, algorithms and problem-solving. I also always try to encourage newer programmers to focus more on their algorithm than the language features itself, because you will always learn the language features as you go along.

Looking at the code, I see you have a clear algorithm there. You know the necessary steps needed to solve your problem, and that is excellent. Now, as you learn more about PHP and its features, you will begin to see more appropriate functions or learn to write more appropriate methods to help you implement your algorithms in the future.

Don't hurt your development as a programmer by thinking of things as "long cuts" or "short cuts". In reality, there are no "short cuts" in programming. Rather, its all about how appropriate your algorithm is and also how you implement it.
