PHP glob Function: Path Pattern Matching
The glob function in PHP is used to retrieve file path names that match a specified pattern. It returns an array containing file or directory paths that match the specified pattern.
Specifically, the function of the glob method is to search for file paths in the filesystem that match a specified pattern, and return these matched file paths as an array. The pattern can include simple wildcards like * or ? to accurately match file names.
Here is the basic syntax of using the glob function:
array glob ( string $pattern [, int $flags = 0 ] )
- $pattern parameter: represents the pattern to be matched, which can include wildcards.
- $flags parameter (optional): Used to set additional flags, such as GLOB_BRACE, GLOB_ONLYDIR, etc.
You can easily list or manipulate files or directories that match a specified pattern using the glob function, which is a commonly used file system operation function.
