Question

i am performing search condition of image file & using print_r() it shows output of image path in array. now i want to store this array & perform search operation for particular image path in that stored array.
this is code of searching image file:

$root1 = $_SERVER[‘DOCUMENT_ROOT’];

$directory = $root1.’/Place4Info/Data/Admin_data/’;

$it = new
RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));
$i=0;
$num=1;
while($it->valid() and $iisDot()) {
$files = glob($directory.$it->getSubPath().’/*.jpg’);
print_r($files);

$i++;
}
$it->next(); }

& output is:

Array ( [0] => C:/Program
Files/EasyPHP-5.3.2i/www/Place4Info/Data/Admin_data/admin/sports19.jpg
[1] => C:/Program
Files/EasyPHP-5.3.2i/www/Place4Info/Data/Admin_data/admin/sports21.jpg
[2] => C:/Program
Files/EasyPHP-5.3.2i/www/Place4Info/Data/Admin_data/admin/sports22.jpg
[3] => C:/Program
Files/EasyPHP-5.3.2i/www/Place4Info/Data/Admin_data/admin/sports3.jpg
)

now i want store this output in a variable or in array.
after that i want to perform search action on that variable or array, like find the path of "C:/Program Files/EasyPHP-5.3.2i/www/Place4Info/Data/Admin_data/admin/sports22.jpg " file. & store that result in variable.
i got one code but i dont know how to apply this.

$conditions = array(“Post.title<>” =>
$files);
$this->Post->find(‘sports3.jpg’,
array(‘conditions’ => $conditions));
echo $this;

but it give error:

Fatal error: Using $this when not in object context in C:\Temp\test.php on line 17

You’re misunderstanding the basics of PHP programming, my friend. Your question is not about how to use arrays but how to avoid a logic error in your programming. See my answer.

$this is a magic variable that always represents the actual instance pointer of a substantiated class. E.g. it makes no sense to use it outside of a non-static class context, which is what you’re doing.

Figure out which class has the correct Post object and use its API appropriately.

e.g.

$post = new Post;
$post->find('sports3.jpg', array('conditions' => $conditions));
