quickest way to find filename

maqmus

In an array I have references to files (somename.jpg , othername.html and onemore.swf).

What shoud be the quickest way to get the filenames with its extension?

Can you tell us a little more about the array?
Is it an ordered array?
What are you going to be searching the array on?
How many elements are you going to be searching for (would it be worthwhile ordering the array)?

In data.php I have arrays like this:

<img src="somefile.jpg" heigth="50" width="30">\n
<a href="somepage.html" target="_blank>My link </a>\n
<object classid=9823749>(the whole code for flash files) myfile.swf .......</object>

Now I want to retrieve the filenames:
somefile.jpg
somepage.html
myfile.swf

I'm not quite sure I'm getting you. Each element of the array has a different reference yes?

$array=array(
  '<img src="imgfile.jpg" />',
  '<a href="pagefile.php">page</a>');

etc yes? If that is the case, what do you want to do with that information? Do you want to pull out the file names and make another array of file names which corresponds to this orriginal array? Do you want to search through the elements to see if a certain filename is present?
You're going to have to be a little more specific about your requirements. As is all I can say is you're going to need a selection of regular expressions.

I will delete some information. For example:

I want to delete the line that contains <img src="somefile.jpg"> but I want to delete the image file too. So, I need to retrieve this name to make unlink() before deleting the line. The problem is that for each case there are different codes ("<a href=...>", "<object>....", <img src>...")

You can do some regexp on the line to extract the filename. See http://regexlib.com/, there might be somthing there.

I was looking at http://regexlib.com/, but couldn't find anything.
