rpm_is_valid — Tests a filename for validity as an RPM file

说明

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.

参数

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

返回值

成功时返回 TRUE ，或者在失败时返回 FALSE 。

范例

}
else {
    echo  "File is not recognized as an RPM file.<br>\n" ;
}

 ?>
