help with str_replace

[gdfhghjdfghgfhf]

i have an array with unserialized stuff....

 

so it output one item per line

 

i use this code to take out one of the item (one line)

 

$a = $row["options"];

$unseri = unserialize($a);

foreach($unseri as $value)
{
$hmm = str_replace("$legroupe", "", "$value");
   echo $hmm."<br />\n";
} 

 

the only problem is that the line is still here, it's just empty. I want to completly remove it.

 

I tryed with    str_replace("$legroupe\n", "", "$value");  but it doesnt replace anything

i dont think it works with variables

i dont think it works with variables

 

uh? what do you mean....

 

it works, it just that it will just remove the word and not the entire line (keeping a line break between 2 items)

$find = "cheese";
$string = "i love cheese";
$hmm = str_replace($find, 'insert word here', $string);
echo $hmm;

 

make sure legroupe is defined

[gdfhghjdfghgfhf]

$legroupe is a defined $_GET value

 

the code of my str_replace is working, but i want it to take out an entire line

 

 

say i want to replace something here:

11111111

222222

3333333

4444444

55555

666666

 

if i replace "4444444" the result will be:

11111111

222222

3333333

 

55555

666666

see? the line is still here, but it's empty

 

i want a result like this:

11111111

222222

3333333

55555

666666

[marcus]

<?php
$mystring = "11111111
222222
3333333
4444444
55555
666666";

$replace = "4444444\r\n";

echo "<pre>" . str_replace($replace, NULL, $mystring) . "</pre>";
?>

 

my results

 

11111111
222222
3333333
55555
666666
