Filtering Arrays help

[herghost]

Hi guys

 

I was wondering if anyone could point me in the right direction with this.

 

I am using JSON to return the contents of a directory and then using a foreach loop to print each one to a new row in a table.

 

Is there anyway to filter the results? Basically I just want to show the files that end in a .jar extension? Currently all sub directories and files are shown, however all the files I need to pull will be in the main directory.

 

This is what I am using:

 

<?php
				foreach ($installedplugins1['success'] as $v) 
			{
				echo "<tr><td>".$v."</td>";
				echo "<td><a href='index.php?dp=".$v."'>Disable Plugin</a></td>";

			}
		?>

 

Any hints or reading material?

 

Cheers

use glob for this.

Where is this data coming from exactly? There may be better ways to get the data initially that would not require any post-processing.

 

But, to answer your question, you can filter an array using the oddly named function array_filter().

use glob for this.

 

@AyKay47: Note that glob() is case sensitive. There is a function that can convert a string into a pattern that will make glob() work in a case insensitive manner, but I cannot find it.

 

 

EDIT: Found it sql_regcase()

heh...

Psycho, my thoughts are that the OP stated he is grabbing files from a directory and looping through them to display them each in a new tbl row.

I'm thinking he can use glob to grab all of the .jar files from the directory and foreach through them that way, something like this:

 

?>
<table>
<?php
foreach(glob("/path/to/dir/*.jar") as $filename)
{
    echo "<tr><td>".$filename."</td>";
    echo "<td><a href='index.php?dp=".$filename."'>Disable Plugin</a></td></tr>";
}
?>
</table>

 

then again, I can only guess on the actual logic at this point.

Unless one of the files happens to be named .JAR, .Jar, etc. Then, using "*.jar" in the glob() function will not work. glob() doesn't accept true regex expressions, but you can build a case-insensitive expression using the function I posted above.

ah, just noticed the edit to your thread, yes that should work, any clue what the non-deprecated function is now, if one exists?.

But again, until the OP responds, we can really only guess at the actual logic and if this will work in this case.

Hi Guys

 

Thanks for all your responses, the data is coming from an API into the minecraft extension bukkit, my actual results from query display as:

 

"result": "success",
    "source": "getDirectory",
    "success": ["plugins/Essentials.jar", "plugins/Essentials/", "plugins/Essentials/config.yml", "plugins/Essentials/items.csv", "plugins/Essentials/upgrades-done.yml", "plugins/Essentials/warps/", "plugins/Essentials/worth.yml", "plugins/JSONAPI.jar", "plugins/JSONAPI/", "plugins/JSONAPI/config.yml", "plugins/JSONAPI/config_rtk.yml", "plugins/JSONAPI/methods.json", "plugins/JSONAPI/methods/", "plugins/JSONAPI/methods/permissions.json", "plugins/JSONAPI/methods/readme.txt", "plugins/JSONAPI/methods/remotetoolkit.json", "plugins/JSONAPI/methods/system.json", "plugins/JSONAPI/methods/world.json", "plugins/MinecraftRKitPlugin.jar", "plugins/PluginMetrics/", "plugins/PluginMetrics/config.yml"]
}

 

So all I am trying to do is extract the results that end in .jar and ignore the rest so I can have a list of installed plugins.

FYI: Here is a case-insensitive glob() solution to find ".jar" files

$files = glob("/path/to/dir/*.".sql_regcase('jar'));

 

BUt, to the OP's problem, since the data is created externally the array_filter() function is probably the correct solution.
