You can use strpos function to find the occurrence of one string within another.

$str1 = '132,139,150,166,176,131,140,151,165,175';
$str2 = '132,139,150,166,176';

if( strpos($str1,$str2) !== false) {
   // $str2 exists within $str1.
}

Note that strpos will return 0 if $str2 is found at the beginning of $str1 which in fact is the case above and will return false if not found anywhere.

You must use the identity operator !== which checks both value and type to compare the return value with false because:

0 !== false is true

where as

0 != false is false

You want strpos 

strrpos("132,139,150,166,176,131,140,151,165,175","132,139,150,166,176");

If a string exists, its starting point will be returned from zero onward, if it is not present the result will be 'false'
