Array values, solving

PHP Code

  
         $uc =;      $WC = Getu_province ();      foreach ($wc as $k = + $v) {          $uv = $v [' $uc '];          $prolist = Join (' 0010 '. $uc);      foreach ($uv as $s = + $a) {         if ($a [0]= $prolist) {          $ucc = $a [' $prolist '];               }      }

$WC something like this array ([0] = = Array ([001011] [+] = Beijing) [1] = = Array ([001012] = Tianjin) [2] = = Array ([001013] (Hebei) ...)

Need to take 001033 of the Chinese value,,,, how to take? It seems that the above is not very right to say;

------Solution--------------------
Is the 0010 fixed? I don't really understand your code.

PHP code

 $testArray = Array (' 001011 ' = ' = ' Beijing '), Array (' 001012 ' = ' Tianjin '), Array (' 001013 ' = ' Hebei ');//$WC = Getu_province (); $uc = n; $find = ' 0010 '. $uc; foreach ($testArray A        S $value) {if (Array_key_exists ($find, $value)) {echo ' region: '. $value [$find];    Break }} 
------solution--------------------
 $uv = $v [' $uc ']; 
 and 
 $uv = $v ["$uc"]; 
 is not the same. 
 
------Solution--------------------
 $uc = 1, 
 "$uc" is "1", and 
 ' $uc ' is the string "$uc" 
 because in double quotes, the variable name is replaced by the value of the variable. Then it will be sent to the browser, and the single quotes will not.

 Test OK!!
   
    
 
    
 by the way $v[$uc]//$v [' $UC ']//$v ["$uc"]; three differences!
