[SOLVED] Split input by lines?

[sam06]

Hopefully this won't take long! ;

 

I'd like to take an input of multiple lines, split it by line, and perform an action with it.

 

e.g.

 

Input:

 

1000

1001

1002

1003

 

And it would do something with 1000, then 1001, then 1002 etc.

 

Any ideas?

 

Many thanks,

Sam

$input = explode("\n",$input);

 

edit:

 

if this input is a text file you are reading, you can use file

[Alex]

$split = explode("\n", $input);

Then the first line would be $split[0], second would be $split[1], etc..

[.josh]

$split = explode("\n", $input);

Then the first line would be $split[0], second would be $split[1], etc..

 

yes.

Many thanks; I'm not too sure how to emplement this though...?

 

I've tried:

 

<?php
$input = $_POST['input'];
$count = 0;
$while = 0;


$split = explode("\n", $input);

while($while == 0) {

if ( $split[$count] == "" ) {

$while = 1 ;


} else {

// my action will go here
echo $count;
echo '                 -       ';
echo $split[$count];
echo '<br>';
//
$count = $count + 1;

}
}
?>

 

It's working, but coming up with:

Notice: Undefined offset: 2 in C:\wamp\www\splitfile.php on line 11

 

Any idea?

You can just use something like:

 

$input = $_POST['input'];
$split = explode("\n", $input);

foreach ($split as $line)
{
    if ($line != '')
    {
        echo $line . '<br />';
    }
}

 

You'll probably want to add a <br /> tag to the end otherwise they'll all be on the same line.

 

Edit: Just seen the <br> you had before!

<?php
$input = $_POST['input'];
$split = explode("\n", $input);

foreach($split as $k){
    echo $k;
}
?>

I think you may be making it more complicated than it need be ...

 

<?php

$input = $_POST['input'];

$split = explode("\n", $input);

foreach ($split as $key => $value) {

     //DO ACTION ON THE INDIVIDUAL SPLIT INDEX
     echo $value . "<br />";

}

?>

<?php

$input = $_POST['input'];

$split = explode("\n", $input);

$key = 0;

$limit = count($split);

while($limit <= 0) {

     //DO ACTION ON THE INDIVIDUAL SPLIT INDEX
     echo $split[$key];

    //INCREMENT FOR THE NEXT ITERATION
    $key++;
}

?>

 

I think you are...

Thanks a lot, I changed it a bit:

$tocheck = isset($split[$count]) ? $split[$count] : '';
if($tocheck == ""){

 

Really appreciate it,

Sam

is this to find the length of the split? if so you can use sizeof($array);

[Adam]

No he's checking if $split[$count] is set, and then doing another if to check if the previous if was successful- bizarre! You could just use a foreach () loop and make things much easier.
