Sample code for variable interaction between PHP and javascript_PHP tutorial

This example is an example of interaction between PHP and JavaScript. The value in PHP is assigned to the JS variable. The premise is that the PHP variable must have a value, even if it is in a fake 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 will occur because $title is assigned an array in php

Although flags=="false" in php; $title is a string, the situation is that $title is an array, and the array cannot be displayed directly in the string of.

Copy code 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";
}
?>
