The function searches for all the pathnames matching according to the rules used by the libc glob() function, which is similar to the rules used by common shells. glob``pattern

The behavior on Unix systems and macOS is determined by the system's implementation of glob(). On Windows, an implementation that conforms to the POSIX 1003.2 definition for glob() is used, and it includes an extension to handle the convention for negating a range. [!...]

**Voorbeeld: Convenient way how can replace and friends. **

<?php
foreach (glob("*.txt") as $filename) {
    echo "$filename size " . filesize($filename) . "\n";
}
?>

funclist.txt size 44686
funcsummary.txt size 267625
quickref.txt size 137820

**Voorbeeld: Example with a more complex pattern **

<?php
foreach (glob("path/*/*.{txt,md}", \GLOB_BRACE) as $filename) {
    echo "$filename\n";
}
