php - How to match string based string on text file -


simply in php replace string other string such using particular function, str_replace (), etc

suppose have file.txt contains

text1 text2 text3 ... text n

and have variable $text like

$text = "i want text1 , text2";

how strings (text1 , text2) based on available strings in file.txt?

i want have new variable ($new) contains strings of $text fits on string file.txt

so have $new="text1 text2";

i still confused, how adjust 2 text.

any wouldbe appreciated. thanks.

do this: 

$filetokens = explode(php_eol, file_get_contents('file.txt')); $texttokens = explode(' ', "i want text1 , text2");  $results = array_intersect($filetokens, $texttokens); var_dump($results);

to results space-delimited string, use line

$stringresults = implode(' ', $results); var_dump($stringresults);
