I have a string that contains many words such as:
$str = "FileZilla Portable FileZilla 3.9
FileZilla Portable Additional Versions
7-Zip Portable 7-Zip Portable 4.42";
I want to delete all dupplicates and return each word only once:
$str = "FileZilla Portable 3.9
FileZilla Portable Additional Versions
7-Zip Portable 4.42";
How can I do it with php ?
Do this:
$str = "FileZilla Portable FileZilla 3.9
FileZilla Portable Additional Versions
7-Zip Portable 7-Zip Portable 4.42";
$arr = array_unique(explode("\n", $str));
$arrLength = count($arr);
for($i = 0; $i < $arrLength; ++$i){
$arr[$i] = implode(" ", array_unique(explode(" ", $arr[$i])));
}
$str = implode("\n", $arr);
echo $str;
Here are the relevant references:
This is my code.
$str = "FileZilla Portable FileZilla 3.9 FileZilla Portable Additional Versions 7Zip Portable 7Zip Portable 4.42";
$arr = explode("\n", $str);
foreach($arr as $st) {
echo implode(" ", array_unique(explode(" ", $st)));
}
But numbers (7Zip) not removing...
