PHP uses the key values of the post array to create a variable with the same name and assign a value to the method

This example describes how PHP creates a variable with the same name and assigns a value using the key value of the post array. Share to everyone for your reference. Specific as follows:

This code can automatically create a variable with the same name based on the key value of the post array, which is very convenient to use without declaring the variable in advance

1 2 3 4 5 6 7 8 9 10 11

$expected =array (' username ', ' age ', ' City ', ' Street '); foreach ($expected as $key) { if (!empty ($_post[$key])) { ${key}=$_post[$key]; } else{ ${key}=null; } } ?>
