This happens if you are trying to use namespaces but do not have PHP 5.3. PHP 5.2 and below don't support namespaces and throw this error when they see the backslash.

Edit: mixed up the versions. It's 5.2 and below that don't have namespaces, if I'm not mistaken.

His PHP version is actually &lt; 5.3.0, whether he knows that or not.

blocks|key|1940382|text|就像其他用户所说的:名称空间的使用只对高于5.3.0的PHP版本有效，所以我的解决方案是通过检查php版本并使用eval()函数来避免较低版本的PHP出现错误，即使在编译时也是如此。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1940383|如下所示：|1940384|if+(+phpversion()+>+'5.3.0'+){

}|code-block|syntax|javascript|1940385|entityMap^0|1A|7|1K|6|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|T|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|U|8|@]|D|@]|E|$K|L]]|$1|M|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|N|$]]

Like other users say: use of namespaces are only valid for PHP versions greater than 5.3.0 so my solution for be able to include an optional use of a library using namespaces is to check the php version and use the eval() function to avoid that lower versions of PHP shoot an error, even on compilation time.

Something like this:

<pre><code>if ( phpversion() &gt; '5.3.0' ){
 include_once('/path/to/Library.php'); 
 eval("Library\Foo::bar();"); 
}
</code></pre>

I ran the same problem, and doing some research I managed to fix it.
In my case, I use PHP7, and what I had to do is edit the file laravel located in <code>~/.composer/vendor/laravel/installer/</code>, where the shebang line was <code>#!/usr/bin/env php</code> I changed to <code>#!/usr/bin/env php7</code>

After run again the artisan, I got it working:

<pre><code>-bash-3.2$ laravel

Options:
 -h, --help Display this help message

My client says he is getting this error using my script:

<pre><code>Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /path/to//header.php on line 34
Parse error: syntax error, unexpected T_STRING, expecting T_CONSTANT_ENCAPSED_STRING or '(' in/path/to/header.php on line 34
</code></pre>

The line 34 in <code>header.php</code> is just <code>use \Main\Class;</code>

Now, I told him he has to have <code>PHP &gt;= 5.3.0</code> and he says his PHP version is <code>5.3.24</code>

What could be the problem?

EDIT: The lines before and after

<pre><code>30. // Define absolute path
31. define("ABSPATH", $abs_path);
32. $_SESSION["abs_path"] = ABSPATH;
33. 
34. use \CNS\main\CNS;
35. $cns = new CNS();
</code></pre>

EDIT 2:

He sent me this:

<pre><code>Program Version
