我正在尝试使用PHP执行bash脚本,但问题是脚本需要在执行过程中输入一些命令和信息。
这就是我正在使用的
$(window).on('resize', function() {
changeSrcset();
});
function changeSrcset() {
var windowWidth = $(window).width();
if (windowWidth <= 544) {
$('.hero-image').attr('srcset', '/static/images/house-544.jpg');
} else if (windowWidth <= 768) {
$('.hero-image').attr('srcset', '/static/images/house-768.jpg');
} else if (windowWidth <= 992) {
$('.hero-image').attr('srcset', '/static/images/house-992.jpg');
} else if (windowWidth <= 1200) {
$('.hero-image').attr('srcset', '/static/images/house-1200.jpg');
} else {
$('.hero-image').attr('srcset', '/static/images/house-1915.jpg');
}
$('.hero-image').css('width', windowWidth);
}
脚本执行OK,但我无法在脚本上输入任何选项。

shell_exec()和exec()无法运行交互式脚本。为此,你需要一个真正的外壳。这是一个为您提供真正的Bash Shell的项目:https://github.com/merlinthemagic/MTS
//if the script requires root access, change the second argument to "true".
$shell = \MTS\Factories::getDevices()->getLocalHost()->getShell('bash', false);
//What string do you expect to show in the terminal just before the first input? Lets say your script simply deletes a file (/tmp/aFile.txt) using "rm". In that case the example would look like this:
//this command will trigger your script and return once the shell displays "rm: remove regular file"
$shell->exeCmd("/my/path/script.sh", "rm: remove regular file");
//to delete we have to press "y", because the delete command returns to the shell prompt after pressing "y", there is no need for a delimiter.
$shell->exeCmd("y");
//done
我确信脚本的返回要复杂得多,但上面的示例为您提供了如何与shell进行交互的模型。
我还要提到你可能会考虑不使用bash脚本来执行一系列事件,而是使用exeCmd()方法逐个发出命令。这样你就可以处理返回并在PHP中保留所有错误逻辑,而不是在PHP和BASH之间拆分它。
阅读文档,它会对您有所帮助。

proc_open()
在没有任何外部库的情况下使这成为可能:
$process = proc_open(
'bash foo.sh',
array( STDIN, STDOUT, STDERR ),
$pipes,
'/absolute/path/to/script/folder/'
);
if ( is_resource( $process ) ) {
fclose( $pipes[0] );
fclose( $pipes[1] );
fclose( $pipes[2] );
proc_close( $process );
}
