Search text file

How can I search for word in text file (Text.txt) using php and give me true if this word is found else false

Thanks

First you open the file, and read it:

PHP Code:

---

$file=join('',file('text1.txt')); 


---

(Of course you can also use fopen, but this is shorter)

Then you look for the word:

PHP Code:

---

if (strpos($word,$file)!==false) //I'm not sure on the order of the arguments, maybe it should be the other way around
   echo 'word found';
else
   echo 'word not found';
