使用mxmlc和“exec”从php编译swf - 加载配置文件，但在浏览器中没有瑞士法郎 [英] Compiling swf from php using mxmlc and "exec" - loading config file but no swf in browser

问题描述

我在RedHat服务器上，有一个简单的PHP页面，它有一个表单，输入名字，电话和网址。

当提交表单时，我运行一个命令来使用mxmlc编译swf。这个命令是这样的：

$ $ $ $ $ $ $ c $ $ generate_command1 =export _JAVA_OPTIONS = \-Xms32m -Xmx64m \; / opt / flex / bin / mxmlc -define + = NAMES :: Name，\\'$ name\'\-define + = NAMES :: Phone，\\'$ phone\'\ - define + = NAMES :: Website，\\'$ url \'\-output /path/to/my/webserver/httpdocs/swfbuilder/generated.swf DynamicTextTest.as;

$ last_line = exec（$ generate_command1，$ out）;
print_r（$ last_line）;

结果总是：

 加载配置文件/opt/flex/frameworks/flex-config.xml 
  

<当我从ssh运行相同的命令到服务器，我实际上得到一个瑞士法郎生成。即

 拾取_JAVA_OPTIONS：-Xms32m -Xmx64m 
加载配置文件/ opt / flex / frameworks / flex-config。 xml 
 /var/www/vhosts/tag.domandtom.com/httpdocs/swfbuilder/generated.swf（945字节）
 [root @ htmlfive swfbuilder]＃
  

目录和文件已经被占用，拥有775 CHMOD'd ...所以我做错了什么让这个工作从网页？我应该有一个分叉的过程，并等待它完成？睡觉？

编辑：

我查看了 fcsh 和其他 mxmlc / java 相关的问题。

解决方案

在重新审查代码时，我注意到，没有逃脱单引号。它们对于实际的执行是有效的，在这种情况下，我应该只能使用PHP的DOUBLE引号...
$ b

最终的代码如下所示（供将来参考）：

 <？php 
 $ name =generated; 
 $ phone =; 
 $ url =; 
 
 if（isset（$ _ POST ['name']））{
 $ name = $ _POST ['name']; 
 
 if（isset（$ _ POST ['phone']））{
 $ phone = $ _POST ['phone']; 
 
 if（isset（$ _ POST ['url']））{
 $ url = $ _POST ['url']; 
} 
 
 $ swfname = $ name。 .swf文件; 
 $ b $ generate_command1 =export _JAVA_OPTIONS = \-Xms32m -Xmx64m \; / opt / flex / bin / mxmlc -define + = NAMES :: Name，\''$ name'\\ \\-define + = NAMES :: Phone，\'$ phone'\-define + = NAMES :: Website，\''$ url'\-output / path / to / my / webserver / httpdocs / swfbuilder / $ swfname DynamicTextTest.as; 
 
 exec（$ generate_command1，$ out）; 
？> 
  

I'm on a RedHat server, with a simple PHP page that has a form, with inputs for name, phone, and url.

When the form is submitted, I run a command to compile a swf using mxmlc. The command is this :

$generate_command1 = "export _JAVA_OPTIONS=\"-Xms32m -Xmx64m\"; /opt/flex/bin/mxmlc -define+=NAMES::Name,\"\'$name\'\" -define+=NAMES::Phone,\"\'$phone\'\" -define+=NAMES::Website,\"\'$url\'\" -output /path/to/my/webserver/httpdocs/swfbuilder/generated.swf DynamicTextTest.as";

$last_line = exec($generate_command1, $out);
print_r($last_line);

The result is always :

Loading configuration file /opt/flex/frameworks/flex-config.xml

When I run the same command from ssh into the server, I actually get a swf generated. I.e.

Picked up _JAVA_OPTIONS: -Xms32m -Xmx64m
Loading configuration file /opt/flex/frameworks/flex-config.xml
/var/www/vhosts/tag.domandtom.com/httpdocs/swfbuilder/generated.swf (945 bytes)
[root@htmlfive swfbuilder]# 

Both directory and files have been CHOWN'd for ownership and CHMOD'd for 775... So what am I doing wrong to get this to work from the web page? Should I have a forked process and wait until it's complete? Sleep?

EDIT:

I've looked into fcsh and other mxmlc / java related questions.

解决方案

In re-reviewing the code, I noticed that I shouldn't have escaped the single-quotes. They're valid for the actual execution and I should only escape DOUBLE quotes for php in this instance...

The final code looks like this (for future reference) :

<?php 
$name = "generated";
$phone = "";
$url = "";

if(isset($_POST['name'])) {
    $name = $_POST['name'];
}
if(isset($_POST['phone'])) {
    $phone = $_POST['phone'];
}
if(isset($_POST['url'])) {
    $url = $_POST['url'];
}

$swfname = $name . ".swf";

$generate_command1 = "export _JAVA_OPTIONS=\"-Xms32m -Xmx64m\"; /opt/flex/bin/mxmlc -define+=NAMES::Name,\"'$name'\" -define+=NAMES::Phone,\"'$phone'\" -define+=NAMES::Website,\"'$url'\" -output /path/to/my/webserver/httpdocs/swfbuilder/$swfname DynamicTextTest.as";

exec($generate_command1, $out);
?>
