[SOLVED] array to string conversion notices

[Cep]

Hello!

 

This is what I am trying to do:

 

I have an array like this,

array ( 
array($path, $ext, $file), 
array($path, $ext, $file),
.....
)

 

I need to split $file to obtain its version number and file name so that I can eventually get the latest version of each file present in the array.

 

So I can change this,

$array = array(
array("\\myplace\", "pdf", "davesfile~001.pdf"),
array("\\myplace\", "pdf", "davesfile~002.pdf"),
array("\\myplace\", "pdf", "davesfile~003.pdf"),
array("\\myplace\", "pdf", "craigsfile~001.pdf"),
array("\\myplace\", "pdf", "craigsfile~002.pdf"),
array("\\myplace\", "pdf", "craigsfile~003.pdf"),
array("\\myplace\", "pdf", "craigsfile~004.pdf"),
array("\\myplace\", "pdf", "waynesfile~003.pdf")
);

 

into this,

 

$array = array(
array("\\myplace\", "pdf", "davesfile~003.pdf"),
array("\\myplace\", "pdf", "craigsfile~004.pdf"),
array("\\myplace\", "pdf", "waynesfile~003.pdf")
);

 

I have started writing a function to do this, it will take the file array as above and foreach sub array it will explode $file into its name and extension and then explode it again to split the name from the version. At this point I am at a stumbling block trying to figure out how to test the data and I keep getting array to string notices when using variable variables.

 

Can anyone help me out?

 

<?php
function sort_files($filearray) {

// Array = (array($path, $ext, $filename),array($path, $ext, $filename));
$myarray = array();
$varray = array();

foreach ($filearray as $fileinfo) {
	// Split name and extension
	$split_name = explode(".", $fileinfo[2]);

	// Split name and version
	$split_further = explode("~", $split_name[0]);

	// Assign filename and version
	$filename = $split_further[0];
	$version = $split_further[1];

	// Assign varray with the filename, eg. $$varray = "myfile"; $myfile = array();
	$$varray = $filename;

	// Find is filename exists in new array
	if (in_array($filename, $myarray)===false) {
		$myarray[] = $filename;
	} else {
		$varray[] = $version;
	}
}

return $myarray;
}

$array = array(
array("here", "ext", "davesfile~001.pdf"),
array("here", "ext", "davesfile~002.pdf"),
array("here", "ext", "davesfile~003.pdf"),
array("here", "ext", "craigsfile~001.pdf"),
array("here", "ext", "craigsfile~002.pdf"),
array("here", "ext", "craigsfile~003.pdf"),
array("here", "ext", "craigsfile~004.pdf"),
array("here", "ext", "waynesfile~003.pdf")
);

$newarray = sort_files($array);
echo "<pre>";
var_dump($newarray);
echo "</pre>";
?>

I lost you on this line:

$$varray = $filename;

 

$varray is an array, so how can you use it in variable-variables?

 

 

Here's how I think it should be (I've tested it and the output was ok):

 

<?php

function sort_files($filearray)
{

$varray = array();

foreach ($filearray as $key => $fileinfo)
{
	// Split name and extension
	$split_name = explode(".", $fileinfo[2]);

	// Split name and version
	$split_further = explode("~", $split_name[0]);

	// Assign filename and version
	$filename = $split_further[0];
	$version = $split_further[1];

	// Set in $varray[$filename] the number of the latest version
	if(!isset($varray[$filename][0]) || intval($version) > intval($varray[$filename][0]))
			$varray[$filename] = array($version, $key);
}

$myarray = array(); //Build the result
foreach($varray as $data)
	$myarray[] = $filearray[$data[1]];

return $myarray;
}

$array = array(
array("here", "ext", "davesfile~001.pdf"),
array("here", "ext", "davesfile~002.pdf"),
array("here", "ext", "davesfile~003.pdf"),
array("here", "ext", "craigsfile~001.pdf"),
array("here", "ext", "craigsfile~002.pdf"),
array("here", "ext", "craigsfile~003.pdf"),
array("here", "ext", "craigsfile~004.pdf"),
array("here", "ext", "waynesfile~003.pdf")
);

$newarray = sort_files($array);
echo "<pre>";
var_dump($newarray);
echo "</pre>";

?>

Hi Orio,

 

Well I was trying to make the name of the container a variable value equal to the filename. The code does actually do this with an array but because filename is a string it throws the notices at you. However I did think the implementation was a bit sketchy at best.

 

Thanks for your help
