#warning＃当我将php文件从一个站点复制到同一个Zend中的另一个站点时，调用未定义的函数'print_r'

问题描述：

enter image description here

I can't really understand what happened here. What I've done was to copy a php file to another project in the same Zend. It's a warning, not an error.
My computer is supposed to have only one php version, so it seems nothing to do with the php version.
the function is standard "print_r", so it seems nothing to do with the undefined function.

the code is very normal, like : print_r ( "image:" );

我真的不明白这里发生了什么。我做的是将php文件复制到另一个项目在同一个Zend。这是一个警告，而不是错误。 p> li>
我的电脑应该只有一个php版本，所以它似乎与php版本无关。 p> li>
该函数是标准的“print_r”，所以它似乎与未定义的函数无关。 li> ul>
代码非常正常，例如：print_r（“image：”）; p> div>

To workaround this problem the user needs to manually add relevant content into the '.buildpath' file.

Close the project (Project | Close Project).
Open the '.buildpath' file that resides in the project's root directory with a text editor. If the file does not exist, create it. Paste the correct contents into the '.buildpath' file:

.buildpath contents for a PHP Project

<?xml version="1.0" encoding="UTF-8"?>
<buildpath>
    <buildpathentry kind="src" path=""/>
    <buildpathentry kind="con" path="org.eclipse.php.core.LANGUAGE"/>
</buildpath>

.buildpath contents for a Zend Framework Project

<?xml version="1.0" encoding="UTF-8"?>
<buildpath>
    <buildpathentry kind="src" path=""/>
    <buildpathentry kind="con" path="org.eclipse.php.core.LANGUAGE"/>
    <buildpathentry kind="con" path="org.zend.php.framework.CONTAINER"/>
</buildpath>

Save the file.
Open your project (Project | Open Project).
Rebuild the project (Project | Clean).

After the build process finishes, you should see no warnings for standard PHP functions.
