sdiff via php (without shell)

Question

Anyone familiar with an equivalent of sdiff (or even diff) but executed via PHP. Note: I cannot use shell_exec() to execute a bash script. Right now I am pulling in two pages and want to compare to see what the delta is. appreciated

I am trying to compare line by line with the equivalent of sdiff -l -w 140 $variable1 $variable2 (which are both imported via cURL0
