括号内的php变量[关闭]

Question

php variable within bracket

What Im trying to do is pull page titles names from DB depending on City

example

$city = "Houston";
$title = $settings['PageTitle$city'];

I get no result even though $settings['PageTitleHouston'] exists in the database

using $settings['PageTitleHouston'] works but I Need $city in the variable as I am doing many cities.

Any suggestions?

( I did search about 30 minutes for answers)

You're very close:

$title = $settings['PageTitle'.$city];

you could also use double quotes:

$title = $settings["PageTitle$city"];

Take a look at the variable parsing page on the PHP manual for more information about PHP and double quotes.
