PHP - Manual: PharFileInfo::__construct

2024-11-13

PharFileInfo::__construct

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)

PharFileInfo::__constructConstruct a Phar entry object

说明

public PharFileInfo::__construct(string $filename)

This should not be called directly. Instead, a PharFileInfo object is initialized by calling Phar::offsetGet() through array access.

参数

filename

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

示例 #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;
}
?>

以上例程会输出:

line number 1: hi
line number 2: there
line number 3: dude
line number 1: hi
line number 2: there
line number 3: dude
