Corresponding string with shell wildcards (e.g. *)

Is it possible to use a wildcard in an if statement?

My code is:

*= wildcard

if ($admin =='*@some.text.here') {

}

$admin will be one of the following:

  • xvilo@some.text.here
  • bot!bot@some.text.here
  • lakjsdflkjasdflkj@some.text.here

If you do not want to use regular expressions, it fnmatch()may serve you well for this [limited] purpose. It matches strings using shell-like wildcards, as you would expect.

if (fnmatch('*@some.text.here', $admin)) {

}

You can simply check if the string ends with the expected value:

$suffix = '@some.text.here';

if (substr($admin, -strlen($suffix)) == $suffix) {
    // Do something
}

*, . ( ).

:
*xxx - "xxx"
xxx* - "xxx"
xx*zz - "xx" "zz"
*xx* - "xx"

function wildcard_match($pattern, $subject)
{
    $pattern='/^'.preg_quote($pattern).'$/';
    $pattern=str_replace('\*', '.*', $pattern);

    if(!preg_match($pattern, $subject, $regs)) return false;
    return true;
