PharFileInfo::__construct
(PECL phar:1.0.0-1.2.1)
PharFileInfo::__construct — Construct a Phar entry object
说明
void PharFileInfo::__construct
( string $entry
)
This should not be called directly. Instead, a PharFileInfo object is initialized by calling Phar::offsetGet() through array access.
参数
- entry
-
The full url to retrieve a file. If you wish to retrieve the information for the file my/file.php from the phar boo.phar, the entry should be phar://boo.phar/my/file.php.
错误／异常
Throws BadMethodCallException if __construct() is called twice. Throws UnexpectedValueException if the phar URL requested is malformed, the requested phar cannot be opened, or the file can't be found within the phar.
范例
Example#1 A PharFileInfo::__construct() example
<?php
try {
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['testfile.txt'] = "hi\nthere\ndude";
$file = $p['testfile.txt'];
foreach ($file as $line => $text) {
echo "line number $line: $text";
}
// this also works
$file = new PharFileInfo('phar:///path/to/my.phar/testfile.txt');
foreach ($file as $line => $text) {
echo "line number $line: $text";
}
} catch (Exception $e) {
echo 'Phar operations failed: ', $e;
}
?>
上例将输出：
line number 1: hi line number 2: there line number 3: dude line number 1: hi line number 2: there line number 3: dude
