For loop with var dump question. - wolfgang1983 - 02-26-2016
When I var dump my $orignal_images. Because it is in the for loop it displays the var dump array multiple times as shown below.
PHP Code:
array (size=6)
0 => string 'assian_creed_3.jpg' (length=18)
1 => string 'assian_creed_4.jpg' (length=18)
2 => string 'ci-logo.png' (length=11)
3 => string 'kitten_1.jpg' (length=12)
4 => string 'nvidia_5-wallpaper-1920x1080.jpg' (length=32)
'sub\' =>
array (size=1)
0 => string 'Windows_7_wallpaper_8_thumb-100x100.jpg' (length=39)
array (size=6)
0 => string 'assian_creed_3.jpg' (length=18)

Question how to only make it display one array result in the var dump.
PHP Code:
$get_directory = $this->input->get('directory');
if (isset($get_directory)) {
$cached_images[] = directory_map('./images/cache/' . $get_directory);
} else {
$cached_images[] = directory_map('./images/cache/catalog/');
}
for ($i=0; $i < count($cached_images); $i++) {
$original_images = str_replace('_thumb-' . $width . 'x' . $height, '', $cached_images[$i]);
var_dump($original_images);
if (isset($get_directory)) {
if (!is_file(FCPATH . 'images/' . $get_directory . '/' . $original_images[$i])) {
if (@unlink(FCPATH . 'images/cache/' . $get_directory . '/' . $cached_images[$i])) {
} else {
}
}
} else {
if (!is_file(FCPATH . 'images/catalog/' . $original_images[$i])) {
if (@unlink(FCPATH . 'images/cache/catalog/' . $cached_images[$i])) {
} else {
}
}
}
}

You can try this:
PHP Code:
$original_images = str_replace('_thumb-' . $width . 'x' . $height, '', $cached_images[$i]);
$temp_images = str_replace('_thumb-' . $width . 'x' . $height, '', $cached_images[$i]);
var_dump($temp_images);
$temp_images = '';
