Linux+nginx using if to determine the problem

Recently encountered a problem: my local Operation project environment is Wamp, and then uploaded to the service space is Linux+nginx. When running locally and running in the WAMP environment, the following feature is absolutely no problem,
But there was a situation in Linux+nginx:
The code that implements the function is the same, and this part of the code is as follows:
$properties _gj = get_goods_properties_gj ($goods _id); Get specifications and attributes for advanced custom products
Var_dump ($properties _gj);
$spe = Array ();
foreach ($properties _gj[' spe '] as $v) {
if ($v [' name '] = = ' plus word ') {
$spe [0] = $v;
}
if ($v [' name '] = = ' appearance material ') {
$spe [1] = $v;
}
if ($v [' name '] = = ' inside material ') {
$spe [2] = $v;
}
}
echo "

";
Var_dump ($spe); exit;
Additional: Print the results of $PROPERTIES_GJ
Array (3) {

In the WAMP environment to print $spe is a value, but in Linux+nginx, print out is empty, how also can not enter if judgment, if the If judgment is removed $spe [0] = $v; $spe [1] = $v; $spe [2] = $v; (or the "=" in the If condition) = "Change to" = "), only get to the situation. On the Linux+nginx, will not be configured, if not configured, there is no solution to the method, thank you for pointing!
