Use fopen() to open the file, while ( ! feof( $fp ) ) to loop through the
file until the end of it is reached and fgets() to read one line at a time.
Use explode() to grab the first word on each line, compare it to your other
variable and write each line to a new variable if it doesn't match. Then
use fwrite to write to a temporary file and copy that file over the
original.
