Please advise, PHP array problem.

This is the problem I see on other websites, please advise

This is a standard array, at a glance, but what does the title=> $Img [' title '] mean?? is the value of title the title of the IMG array? Or what? $item =array (' title ' = ' + $Img [' title '], ' description ' + $Img [' text '], ' pic ' = $Img [' pic '], ' url ' =>$ URL), array (' title ' = = $Img [' title '], ' description ' = ' + ' $Img [' text '], ' pic ' + $Img [' pic '], ' url ' = = $url), Array (' title ' = = $Img [' title '], ' description ' and ' = ' $Img [' text '], ' pic ' + $Img [' pic '], ' url ' = = $url), Array (' Title ' = ' $Img [' title '], ' description ' and ' + ' $Img [' text '], ' pic ' + $Img [' pic '], ' url ' = ' + $url ');

The following array is more complex, please point, what does it mean to arrive?? Please detail, novice ...
Array (9) {
[0] = = Array (4) {
["title"] and string (21) "What is a pin?" "
["Text"] + string (66) "PIN is a modern low-cost, high-performance marketing means. "
["pic"] = + string "http://cdn.ipai.com/1396127866.jpg"
["url"] + = string (0) ""
}
[1] = = Array (4) {
["title"] + string (23) "Article Mai Rotten"
["text"] + = string (23) "Article Mai Rotten"
["pic"] = + string "http://cdn.ipii.com/1397285480.jpg"
["url"] + = string (0) ""
}
[2] = = Array (4) {
["title"] + = string (18) "Click to Change Password"
["text"] + = string (0) ""
["pic"] = + string "Http://cdn.44.com/1398879995.png"
["url"] = = string "http://v.44.com/index/reg/wecha/". $formuser. ' /shtml "
}
[3] = = Array (4) {
["title"] + string (4) "M Horse"
["text"] + = string (6) "description"
["pic"] = + string "http://cdn.ip.com/1398638713.jpg"
["url"] + = string (0) ""
}
};

Array (' title ' = = $Img [' title '])
Refers to the key value of the key named title = $IMG The value of the key named title in the array;

You said the second more complex array, it is not complex, it is just a normal two-dimensional array, it is printed to show array (4), Array (4), do not interpret this as an array.
You define a two-dimensional array, and then Var_dump ($arr) will know.

$a = $Img [' title '];........array (' title ' = = $a,........

It's your equivalent.

Array (' title ' = = $Img [' title '])
Refers to the key value of the key named title = $IMG The value of the key named title in the array;

Thanks, I know.
