Hi guys...

One of you kind gentlemen helped me with a glob function which works great.
Id like to just modify it slightly.
Here is a quick code snippet..

foreach ( glob('*.php') as $filename ) {

In the above, this finds all php files in a folder.
Id like to just find php files that start with the following....

menu
followed by
a number (1 digit long)
then any character/s
followed by
.php

So, for example,

menu1_it_shhjksdfljldjsf.php    (it would find this)
backup.menu3_it_sdfs.php    (it would NOT find this)
menu_templates.php         (it would NOT find this because it doesnt have a digit after menu)


So, i just need

foreach ( glob('*.php') as $filename ) {

modified to be something like

foreach ( glob ('^menu<a digit number>*.php') as $filename )

Ive tried the above but it doesnt work.

Any help greatly appreciated.

Something with regular expressions should work:
$pattern = "/\(^menu[0-9]\)\([a-zA-Z0-9]\)/";
 
foreach ( glob('*.php') as $filename ) {
 
	if (preg_match($pattern,$filename) == 1) {
	
		//do what you like with the file
 
	}
 
}

Hi JurgenvH,
Im having issues Jurgen with embedding the above regEX into my exisiting code.
The below file is where i have embedded it.

 <?php
 
 // Make a MySQL Connection
 mysql_connect("localhost", "root", "password") or die(mysql_error());
 mysql_select_db("simeswiki") or die(mysql_error());
 
 
 // Examine the files on disk --> loop through them --> create records in filename_fil table.
 
 $pattern = "/\(^menu[0-9]\)\([a-zA-Z0-9]\)/";
 
 foreach ( glob('*.php') as $filename ) {
 
                 if (preg_match($pattern,$filename) == 1) {
 
                         $query =  "select count(*) from filename_fil where file_fil='$filename'";
 
                         if (false == ($r = mysql_query($query))){
                                 die("Query failed: $query.<br />MySQL said: " . mysql_error());
                         }
                 }
 
                         list ( $cnt ) = mysql_fetch_row($r);
 
                                 if ( $cnt ) {
                                 // file exists in the database, do nothing..
                                  }
 
                                 else {
                                 // file does not exist
 
                                         $query = "insert into filename_fil (file_fil) values ('$filename')";
 
                                         if (false === mysql_query($query)){
                                                 die("The query failed: $query.<br />MySQL said: " . mysql_error());
                                         }
                                 }
 }
 
 
 // Examine entries in the database --> while looking at each, delete the db record if it does not exist on disk.
 
 $query = "SELECT file_fil FROM filename_fil";
 if (false === ($results = mysql_query($query)))
 {
    die("Query failed: $query. MySQL said: " . mysql_error());
 }
 
 while (false !== ($row = mysql_fetch_object($results)))

Sorry, I made it to complicated. :-)
I think this is what you want. Works for me!
<?php
 
// Make a MySQL Connection
mysql_connect("localhost", "root", "password") or die(mysql_error());
mysql_select_db("simeswiki") or die(mysql_error());
 
 
// Examine the files on disk --> loop through them --> create records in filename_fil table.
 
foreach ( glob('*.php') as $filename ) {
 
	$pattern = "/^menu[0-9]/";
 
	if (preg_match($pattern,$filename) == 1) {
 
		$query =  "select count(*) from filename_fil where file_fil='$filename'";
 
		if (false == ($r = mysql_query($query))){
			die("Query failed: $query.<br />MySQL said: " . mysql_error());
		}
 
		$cnt = mysql_num_rows($r);
 
		if ( $cnt > 0) {
			// file exists in the database, do nothing..
		} else {
			// file does not exist
			$query = "insert into filename_fil (file_fil) values ('$filename')";
 
			if (false === mysql_query($query)){
				die("The query failed: $query.<br />MySQL said: " . mysql_error());
			}
		}
	}
 
}
 
 
// Examine entries in the database --> while looking at each, delete the db record if it does not exist on disk.
 
$query = "SELECT file_fil FROM filename_fil";
if (false === ($results = mysql_query($query))) {
	die("Query failed: $query. MySQL said: " . mysql_error());
}
 
while (false !== ($row = mysql_fetch_object($results)))
{
	echo "Examine ".$row->file_fil."<br/>";
	if (!file_exists($row->file_fil)) {
        $deleteQuery = "DELETE FROM filename_fil WHERE file_fil='$row->file_fil' LIMIT 1;";
        if (false === mysql_query($deleteQuery)) {
			die("Query failed: $query.<br />MySQL said: " . mysql_error());
        } else {
			echo "File does not exists; deleted.<br/>";
		}
    }
}
?>

Hi again Simon336697 :) I think you haven't read the manual of the glob function very carefully. There stands, that you can give any shell pattern as parameter to it. So you just need to write :

glob ( "menu[0123456789]*.php" )

Hi tkalchev,

Its not working for me.
I have tried the following, and it is not doing as expected.
I only want entries that start with menu[0123456789]*.php to be inserted into the database.
Now no new entries with the above criteria are being inserted, in fact I dont think anything new is.
Also, nothing is being removed from the database if that file no longer exists on disk, which is what my previous code did do.

In the code snippet below is my original code that did the following..

1) Inserted all php files from the current folder into the database
2) Removed any entries from the database if no longer exist on disk

All i want to do now is just to limit the entries into the database by only inserting ones that start with menu[0123456789]*.php

Here is that code..


 <?php
 
 // Make a MySQL Connection
 mysql_connect("localhost", "root", "password") or die(mysql_error());
 mysql_select_db("simeswiki") or die(mysql_error());
 
 
 // Examine the files on disk --> loop through them --> create records in filename_fil table.
 
 foreach ( glob('*.php') as $filename ) {
         $query =  "select count(*) from filename_fil where file_fil='$filename'";
                 if (false == ($r = mysql_query($query)))
                 {
                 die("Query failed: $query.<br />MySQL said: " . mysql_error());
         }
   list ( $cnt ) = mysql_fetch_row($r);
   if ( $cnt ) {
       // file exists in the database
   }
   else {
      // file does not exist
 
 $query = "insert into filename_fil (file_fil) values ('$filename')";
 if (false === mysql_query($query))
 {
    die("The query failed: $query.<br />MySQL said: " . mysql_error());
 }
   }
 }
 
 
 // Examine entries in the database --> while looking at each, delete the db record if it does not exist on disk.
 
 $query = "SELECT file_fil FROM filename_fil";
 if (false === ($results = mysql_query($query)))
 {
    die("Query failed: $query. MySQL said: " . mysql_error());
 }
 
 while (false !== ($row = mysql_fetch_object($results)))
 {
    if (!file_exists($row->file_fil))
    {
         $deleteQuery = "DELETE FROM filename_fil WHERE file_fil='$row->file_fil' LIMIT 1;";
         if (false === mysql_query($deleteQuery))
         {
              die("Query failed: $query.<br />MySQL said: " . mysql_error());
         }
     }
 }
 
 ?>
