Zend Studio function does not remind small yellow icon small yellow mark

When writing a PHP project with Zend Studio, it is normal to debug when calling system functions, but when writing code, the function is not defined as "call to undefined function", and the left-side syntax detection status area bar always displays an exclamation point of a small yellow triangle.
**‘

Workaround:

1. Modify the project. BuildPath file

<?xml version="1.0" encoding="UTF-8"?><buildpath> <buildpathentry kind="src" path=""/> <buildpathentry kind="con" path="org.eclipse.php.core.LANGUAGE"/># 新增一句 kind="con"</buildpath>

If there is no. buildpath file, create a new one with the contents:

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

2. Resetting the Project compilation state

Clean all projects, Project, clean

3, restart Zend Studiol

4, Complete! And see if the little yellow cold number icon disappears.

Reminder: The PHP Language library contains system functions and definition prototypes of extension library functions that Zend Studio can follow to code hints and complements based on these definition prototypes when calling these functions during encoding.
