1. First, get the contents of file 1.txt, and cut it according to the line break to get an array $ex 1.

2. Cut the contents of file2.txt into the array $ex2 in the same way.

3. Cycle $ex 1 array (it should be file 1.txt file2.txt, and cycle file 1.txt when the number of rows is different).

Set a random number in the loop.

Combine the corresponding contents in $ ex1$ ex 2 into a record and save it to file3.txt

Finally, file3.txt is the result you want.

//Get the contents of file 1

$ contents 2 = file _ get _ contents(' file 2 . txt ')；

//Cut the array with line breaks

$ count 1 = count($ ex 1)；

$ count 2 = count($ ex2)；

//Loop values and assign values

for($ I = 0； $ i & lt$ count 1； $i++){

//Set the random number

$j = rand(0，$ count 1- 1)；

Content 3. = $ex 1[$j]。 $ex2[$i]。 '

;

}

//Write file

file_put_contents('file3.txt '，$ contents 3)；

You can copy this code and create a new file 1.txt file2.txt to write the corresponding test content (note that the line has been broken).
