rpm_is_valid — Tests a filename for validity as an RPM file

### Description

bool rpm_is_valid ( string `$filename` )

rpm_is_valid() will test an RPM file for validity as an RPM file. This is not the same as rpm_open() as it only checks the file for validity but does not return a file pointer to be used by further functions.

### Parameters

`filename`

  The filename of the RPM file you wish to check for validity.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example#1 rpm_is_valid() example

`<?php
$file = "/path/to/file.rpm";
if (rpm_is_valid($file)) {
echo "File is recognized as an RPM file.<br>\n";
}
else {
echo "File is not recognized as an RPM file.<br>\n";
}
?>`
