SplFileInfo::isExecutable — Tells if the file is executable
Checks if the file is executable.
此函数没有参数。
Returns TRUE
if executable, FALSE
otherwise.
Example #1 SplFileInfo::isExecutable() example
<?php
$info = new SplFileInfo ( '/usr/bin/php' );
var_dump ( $info -> isExecutable ());
$info = new SplFileInfo ( '/usr/bin' );
var_dump ( $info -> isExecutable ());
$info = new SplFileInfo ( 'foo' );
var_dump ( $info -> isExecutable ());
?>
以上例程的输出类似于:
bool(true) bool(true) bool(false)
