php filter word code.. need help

hi. i need your help.

content of word.txt:
abc
def
ghi
--EOF--

this is the code


<?php
$word = file_get_contents("./word.txt");
$wordarray = explode("\n",$word);
$string = "Aabc test1 Ddef test2 ghi";
foreach($wordarray as $output)
{
$string = eregi_replace($output, "", $string);
}
echo $string;
?>


the output is:

A test1 D test2

BUT! i want to remove the exact word.

i.e. in this case, only ghi to be removed.

so the output must be

Aabc test1 Ddef test2

 

Add space before and after word and replace by a space ?

 

When I run that code I get
"Aabc test1 Ddef test2" ????

If your still having problems try

That also works for me.

 

you shouldn't be using ereg_replace, as it is considered sort of bad practice and is going to be dropped from php6 I guess. try this:

$string = preg_replace("/\b".$output."\b/", "", $string);

\b stands for word boundary.
