file_get_contents line by line?

[peter11]

Hi all,

 

My application asks questions that it gets from a random text file however i wish to have like part 1, part 2 and part 3 of each question.

 

At the moment i am using the file_get_contents function and opening the file and echo'ing part 1 of the question. I could easily put part 2 in a different text file however it would also pick that at random and i want part 2 to match up with part one. Therefore what code should i use if i want to have a .txt file with the first part of the question on line 1 the second part on line 2 and the third on line 3. I wish to echo each line into separate a variable.

 

Thanks for the help

I you want to store each line into an array you can use the file function as shown below

 

<?php

 

$lines  = @file("file.txt");

 

foreach($lines  as $line ){

 

echo $line;

}

 

?>

@syed Remove the @-operator

why?

[peter11]

What i mean is,

 

On that text file i want line to to be saved as $line1 and the second line of that text file to be saved as $line2.

 

Is that possable?

[ignace]

why?

 

Because it hides error's the OP would wish to see/handle himself. The @-operator suppresses these and the OP will have a hard time figuring out why it doesn't work.

I still don’t get how i would do this is i wanted to assign a separate variable per line.

 

:S

You can do that like this using something like this:

 

$file = file('file.txt');
foreach($file as $key => $line){
    ${'line' . ($key + 1)} = $line;
}

 

But I don't see any need for that. Why create extra variables when you can just access the lines like $file[0], $file[1], etc..

[syed]

Yes but, you have to loop throuhg it first,

 

<?php

$lines  = @file("file.txt");

$i=1;

foreach($lines  as $line ){

 

$var["line" . $i] = $line;

$i++;

}

 

extract($var);

 

echo $line1;

echo $line2;

?>

@syed Stop posting code which uses the @-operator you hide useful error messages for the OP which they can hide themselves using display_errors = 'Off'. You don't need the @-operator.

[syed]

Yes the OP can take it off, are you suggesting that they are not capable of doing this? If the OP wants to see the error messages they can take it off.

[ignace]

It's bad practice. Error's are there for a reason.

[peter11]

Yer i want to see the error if i get one.

 

Do i want to do it like this to see the error:

$lines  = file("file.txt");

 

??

[syed]

Are you telling me in a live enviroment you would not have the at sign to surpress error messages?

[syed]

Yes, I guess you learned somthing new.

[ignace]

Are you telling me in a live enviroment you would not have the at sign to surpress error messages?

 

Indeed. To be honest I have never used the @-operator anywhere on any live site.

[peter11]

thanks,

 

I will test it out in a bit and get back to you

 

Thanks

[peter11]

yer it works perfect

 

If anyone has time can you explane what each bit is doing please i want to learn it in more detail

 

thanks and thanks
