PharFileInfo::chmod

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

PharFileInfo::chmodSets file-specific permission bits

说明

public PharFileInfo::chmod ( int $permissions ) : void

PharFileInfo::chmod() allows setting of the executable file permissions bit, as well as read-only bits. Writeable bits are ignored, and set at runtime based on the phar.readonly INI variable. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed if the file is within a Phar archive. Files within PharData archives do not have this restriction.

参数

permissions

permissions (see chmod())

返回值

范例

Example #1 A PharFileInfo::chmod() example

<?php
// make sure it doesn't exist
@unlink('brandnewphar.phar');
try {
    
$p = new Phar('brandnewphar.phar'0'brandnewphar.phar');
    
$p['file.sh'] = '#!/usr/local/lib/php
    <?php echo "hi"; ?>'
;
    
// set executable bit
    
$p['file.sh']->chmod(0555);
    
var_dump($p['file.sh']->isExecutable());
} catch (
Exception $e) {
    echo 
'Could not create/modify phar: '$e;
}
?>

以上例程会输出:

bool(true)
