rpm_is_valid

(PECL rpmreader:0.1-0.3)

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

如果成功则返回 TRUE，失败则返回 FALSE。

范例

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";
}

?>
