How I delete sentence that specific word in it?

[ChaoscripT]

I have text file with this pattern:
text text text text text text - Site 1

text text text text text text - Site 2

text text text text text text - Site 3

text text text text text text - Site 5

text text text text text text - Site 1

The word "Site" is change in every sentence.
I want that all where is "Site 1" showed, it's will delete the whole sentence.

Thanks, I don't need tool,
I need in PHP code.

Regards.

 

[deliteblogger]

$new_text = preg_replace('/(^.+Site 1$)/mU', '', $text)

This will search for Site 1 at the end of each line, and if it's found, the line will be deleted.

Thanks for that,
But if I have text file with 100 lines, How I check each line ?

Regard.s

 

[deliteblogger]

What do you mean?
This will check each line. $text contains the whole text. I assume you know how to get the contents of a file.

 

[ChaoscripT]

Sorry don't works,
This is the code that I put :

$file = file_get_contents("test.txt");

$new_text = preg_replace('/(^.+Site 1$)/mU', '', $file);

echo "This is new text: ";
echo $new_text;

Regards.

 

[deliteblogger]

ok, remove the $ from the pattern and the U at the end.

@deliteblogger,
Works great,
Now there is any way to do that every words: "Site 1, Site 3, Site 5" will delete ? or just to that :
$new_text = preg_replace('/(^.+Site 1)/m', '', $file);
$new_text = preg_replace('/(^.+Site 3)/m', '', $file);
$new_text = preg_replace('/(^.+Site 5)/m', '', $file);

Regards.

$new_text = preg_replace('/(^.+Site [0-9]+)/m', '', $file);

 

[ChaoscripT]

Not works.

Regards.

 

[deliteblogger]

Do you want to delete lines which end by 'Site 1' and also delete 'Site x' from the end of each line?

$new_text = preg_replace('/(^.+Site 1|Site [0-9]+)/m', '', $file);

 

[ChaoscripT]

Thx deliteblogger,
And if I want for example that it will delete all "Site" and number bigger then 19, Site 19/20/21/22 - 40?
Numbers 19-40 only.

Regards.

 

[deliteblogger]

I don't get it completely. The pattern for 'Site 19' to 'Site 40' inclusive will be something like

Site (19|[23][0-9]|40)
