    <p>I'm using SWIG to integrate a C++ class into PHP, but for some reason the class does not appear correctly in PHP, even though a function does appear correctly. This is SWIG 2.0.4 and PHP 5.3.6 on Mac OS X 10.5.8. Here is the code and the commands used to build the library:</p> <pre><code>$ cat example.i %{ #include &lt;stdio.h&gt; #include "example.h" int Example::foo(void) { printf("This is foo\n"); return 0; } %} %module example class Example { public: int foo(void); }; $ cat example.h class Example { public: int foo(void); }; $ make ehphp /opt/local/bin/swig -c++ -php5 example.i g++ `php-config --includes` -fPIC -c example_wrap.cpp -o example_wrap.o g++ -dynamiclib -Wl,-flat_namespace,-U,_zend_register_resource,-U,_zend_rsrc_list_get_rsrc_type,-U,_zend_wrong_param_count,-U,_compiler_globals,-U,_zend_hash_find,-U,_gc_remove_zval_from_buffer,-U,_zend_register_long_constant,-U,_zend_get_constant,-U,__efree,-U,__emalloc,-U,_zend_error,-U,__zend_list_find,-U,_main,-U,__zend_get_parameters_array_ex,-U,_zend_register_list_destructors_ex,-U,__zval_copy_ctor_func,-U,__convert_to_string,-U,__zend_hash_add_or_update,-U,_executor_globals,-U,_zval_used_for_init,-U,_zval_is_true,-U,__object_init,-U,_php_strtolower,-U,__estrndup,-U,__object_init_ex,-U,_zend_lookup_class -o ehphp.dylib example_wrap.o sudo cp ehphp.dylib /opt/local/lib/php/extensions/no-debug-non-zts-20090626/ehphp.dylib $ php -a Interactive shell php &gt; var_dump(dl("ehphp.dylib")); bool(true) php &gt; var_dump(function_exists("bar")); bool(true) php &gt; var_dump(class_exists("Example")); bool(false) php &gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
