This example shows the interaction between PHP and javascript. The value in php is assigned to the js variable, provided that the php variable must have a value, even in a false branch.

For example, $ flags in php is true in this example. If the false statement in js is written as: $ title_1.innerHTML =" "; An error occurs on the Hong Kong server because $ title is assigned as an array in php.

Although flags = "false"; $ title in php is a string, the case is that $ title is an array, an American server, a VM, arrays cannot be directly displayed in strings.

The Code is as follows:

$ String = "Heaven and Earth ";
$ Flags = "";
If (strpbrk ($ string, "and ")! = False ){
$ Title = explode ("and", $ string );
$ Title_1 = $ title [0];
$ Title_2 = $ title [1];
$ Flags = "true ";
}
Else {
$ Title = $ string;
$ Flags = "false ";
}
?>

-> Html
