and named it 'replace.txt' now my question is how i can load this text file for string replace function replace with empty

I would suggest by using phps file functions to open and read the lines, one by one, into an array. Or reading it at once and exploding the content afterwards into an array. What is the question here? — arkascha

Do you want to use the values in replace.txt as the array you pass as the first parameter to str_replace? — user5051310

Try this

$text = file_get_contents("replace.txt"); $terms = explode("\n", $text); $string = "Hello World"; $string = str_replace($terms, '', $string); echo($string);

I edited this so replace.txt is the terms that are removed

Although the question isn't clearly stated, I suppose it's essentially this: You have a file with text (i.e. words separated by spaces) and you want to delete all words that occur in the list.

Assume $text contains the text to process, and $terms the lines like you posted above. Turn both into an array:

 $text = explode(' ', $text);
 $terms = explode("\n", $terms);
 $text = array_diff($text, $terms);
 $text = implode(' ', $text);

Of course you may need extra processing to get rid of punctuation and other stuff, but array_diff is essentially what does the job.
