To convert string to int in PHP you can use casting or intval() function. See example:

 $intVariable = intval( $unknownVariable );
 
 // or:
 
 $intVariable = (int)$unknownVariable;

You can cast with this function every php variable, like double. Remember that php can throw a error or warning, especially if variable is not set
