The glob function searches for all the pathnames matching pattern according to the rules used by the libc glob function, which is similar to the rules used by common shells. No tilde expansion or parameter substitution is done. If the first character is! Note : On some systems it is impossible to distinguish between empty match and an error.
Version Description 5. Example 1 Convenient way how glob can replace opendir and friends. Note : This function will not work on remote files as the file to be examined must be accessible via the server's filesystem. Note : This function isn't available on some systems e. Edit Report a Bug. Parameters pattern The pattern. Changelog Version Description 5. Examples Example 1 Convenient way how glob can replace opendir and friends.
Notes Note : This function will not work on remote files as the file to be examined must be accessible via the server's filesystem. See Also opendir - Open directory handle readdir - Read entry from directory handle closedir - Close directory handle fnmatch - Match filename against a pattern. Since I feel this is rather vague and non-helpful, I thought I'd make a post detailing the mechanics of the glob regex.
Executing glob "a?. You can also use ranges of characters inside the character class by having a starting and ending character with a hyphen in between.
For example, [a-z] will match any letter between a and z,  will match any one number, etc.. Note: using alternation with single characters like that is the same thing as just doing glob "[abc]. For instance, if you have the following files: a. If you are trying to do something like this, you can first narrow it down with glob, and then get exact matches with a full flavored regex engine. Those of you with PHP 5 don't have to come up with these wild functions to scan a directory recursively: the SPL can do it.
This means it does not return files that start with a dot e. PHP can create such directories quite easily like so: mkdir " core" ;. As a follow up to recursively determining all paths by viajy at yoyo dot org and opendir being faster than glob by Sam Yong - hellclanner at live [dot] com. The list all dirs code didn't seem to work, at least on my server provided by parazuce [at] gmail [dot] com.
This is so I can simply loop through the array, create an expandable link on the folder name, with all the files inside it. You can use multiple asterisks with the glob - function. First off, it's nice to see all of the different takes on this. Thanks for all of the great examples. Fascinated by the foreach usage I was curious how it might work with a for loop.
I found that glob was well suited for this, especially compared to opendir. The for loop is always efficient when you want to protect against a potential endless loop. Also you can tweak it for searches with something like this You get an "Allowed memory size of XYZ bytes exhausted Mine has MB set and the script will still reach this limit while glob ing over I lost hours looking for the solution for this problem.
Maybe all of you still know this, but it seems that if the directory contains some unresolved symlink, glob simply ignore those files.
Non-recursive search files, proceeding down directory tree. A simple function that find all files by extension an return it by an array. Here is simple function that will find and remove all files except ". Use this to exclude hidden files on MS Windows. A solution if you want to avoid getting drive letters into your code is to chdir first, then just look for the file.
You can do a recursive file search with yield. The example on this page will generate a warning if the glob function does not find any filenames that match the pattern.
The glob function result will only be an array if it finds some files and the foreach statement requires its argument to be an array. By checking for the possibility that the result of the glob function may not be an array you can eliminate the warning.
Here is a function that returns specific files in an array, with all of the details. Includes some basic garbage checking. I have been working towards a CMS-type design that is both modular and quite flat. For example, included files are all one level below the installation folder. For those who need to recursively search a directory tree and cannot or wish not to call a function within itself here is another suggestion.
There are two variations on the same theme. Single Array. A couple of notes: glob handles symbolic filesystem links and resolves references to '. This is good to use so warnings or errors show as ".. Watch the flags must not be strings. They are defined constants.
Thus, glob ".. Note that when the documentation says the files will be returned in "alphabetical" order, you may not get the results you expect if your files are numbered. For example, files will be returned in the following order: file.
You can even set the order to post-order or pre-order traversal. I have a scenario where there can be a thousand or more files to check for where I can't pattern match and need to check specific names. I was hoping to batch them in large groups to see if it would help performance.

Ways to Use ‘find’ Command to Search Directories More Efficiently
In some cases you would need to find the location of a given file or to search for a certain text in all files under a directory. SSH provides two different commands, which can be used to accomplish this. In order to search for a file location you can use the find command. Find is a very powerful tool and accepts various arguments allowing you to specify the exact search term i.
Each technology has uses outside of this context, of course, but within it they form something greater than the sum of their parts. This book shows you how to take full advantage of this power, walking you through all the steps required to lay your Linux foundation, install and configure your Apache web server, and then begin using PHP to access content stored in MySQL. Here are a few of the specific topics you'll find covered inside:.
Use the Unix find command to search for files
To use the find command, at the Unix prompt, enter:. Leave the double quotes in. The find command will begin looking in the starting directory you specify and proceed to search through all accessible subdirectories. You may specify more than one starting directory for searching.

However, there are several ways to use the command line to find files in Linux, no matter what desktop manager you use. The simplest form of the command searches for files in the current directory and recursively through its subdirectories that match the supplied search criteria. You can search for files by name, owner, group, type, permissions, date, and other criteria. To find files that match a specific pattern, use the -name argument.
GNU find searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence see section OPERATORS , until the outcome is known the left hand side is false for and operations, true for or , at which point find moves on to the next file name. If you are using find in an environment where security is important for example if you are using it to search directories that are writable by other users , you should read the "Security Considerations" chapter of the findutils documentation, which is called Finding Files and comes with findutils. That document also includes a lot more detail and discussion than this manual page, so you may find it a more useful source of information. That argument and any following arguments are taken to be the expression describing what is to be searched for. If no paths are given, the current directory is used. If no expression is given, the expression -print is used but you should probably consider using -print0 instead, anyway. These options control the behaviour of find but are specified immediately after the last path name.
How to limit search a specified directory in Linux? It searches the directory tree rooted at each given starting-point by evaluating the given expression from left to right, according to the rules of precedence, until the outcome is known the left-hand side is false for and operations, true for or , at which point find moves on to the next file name. The find command by default travels down the entire directory tree recursively, which is time and resource consuming.
