PHP checks whether the data in FORM is an integer.

: This article mainly introduces PHP to determine whether the data in FORM is an integer. if you are interested in the PHP Tutorial, refer to it. The is_int function cannot determine whether the data from FORM is an integer because FORM is a string. Is_numeric can be used to determine whether the data type is numeric. you can use an integer to check whether the data type is numeric.

If (! Is_numeric ($ jp_total) | strpos ($ jp_total ,".")! = False) {echo "not an integer";} else {echo "is an integer ";}

The above describes whether PHP judges whether the data in FORM is an integer, including some content, and hopes to help friends who are interested in PHP tutorials.
