Find numeric value in csv

Question

I need to check if a particular numeric id is in a given string or comma separated values.

$myVal = 20;

String could contain just a single valu

Answer 1

You could use explode to split the string into an array. Something like:

$parts = explode(',', $str);

Then you could use in_array on that.

If you're reading a file, take a look at fgetcsv or str_getcsv.
