is_file和zend框架路由

Question

I have a problem when checking if a file exists in zend framework 2:

When checking:

is_file("/usr/local/zend/apache2/htdocs/my_viena/panel/public/img/familias/101.jpg")

which is the absolute route in my computer, it returns true.

When checking:

is_file($this->basePath()."/img/familias/101.jpg")

which is the route from the module, it returns false.

If I make:

echo "<img src='".$this->basePath()."/img/familias/101.jpg'>";

the browser shows de image correctly.

What is wrong in my code? I want to check if the file exists with the relative route.

Answer 1

In one situation $this->basePath() will return and empty string. And when checking if your file exists it will search for the absolute path /img/familias/101.jpg

echo "<img src='".$this->basePath()."/img/familias/101.jpg'>"; will show the image because it will load something like this www.yoursite.com/img/familias/101.jpg

public/img/familias/101.jpg works because everything in zf2 is realtive to the public folder (I think)

side note don't use echo for creating your tags
