fann_read_train_from_file — 读取存储训练数据的文件。
filename输入文件的格式如下:
num_train_data num_input num_output inputdata separated by space outputdata separated by space . . . inputdata separated by space outputdata separated by space
成功时返回训练数据 资源，发生错误返回 false。
示例 #1 fann_read_train_from_file() 函数的使用范例：
<?php
$train_data = fann_read_train_from_file("xor.data");
if ($train_data) {
// Do something with $train_data for XOR function
}
?>xor.data 文件的内容：
4 2 1 -1 -1 -1 -1 1 1 1 -1 1 1 1 -1
