問題與陣列需要所以首先調整串

Question

你好，大家好，我有這樣的代碼：

$crumbs = array(); 
$crumbs[] = "<a href=\"/\">Triple O Dental Laboratory</a>"; 

if (is_array($GLOBALS["cookie_crumbs"])) { 
    foreach($GLOBALS["cookie_crumbs"] as $mycrumb) { 
     $mycrumb[1] = str_replace("//","/",$mycrumb[1]); 
     $crumbs[] = "<a href=\"".$mycrumb[1]."\">".$mycrumb[0]."</a> > <a href=\"#\">Smile TRU</a>"; 
    } 
} 

print "<div class=\"cookie_crumbs2\">\n"; 
print implode(" > ",$crumbs); 
print "</div>\n"; 

現在的問題是，我試圖刪除這部分代碼：

> <a href=\"http://stage.tripleodentallabs.com/laboratory/smile-tru/\">Smile TRU</a>"; 

但僅僅從陣列中的最後一個項目，因此現在非常的像這樣得到的輸出：http://puu.sh/74ure.png

但我希望「>大單」，從爲「認可六的最後一項帶走DEO」。

Answer 1

首先計算麪包屑，然後在循環中檢查您是否正在處理最後一個。前提是「cookie_crumbs」的數組索引數字形式0：

$last = count($GLOBALS["cookie_crumbs"]) - 1; 

foreach ($GLOBALS["cookie_crumbs"] as $index => $mycrumb) { 

    if ($index === $last) { 

     $crumbs[] = 'I am the last one'; // do whatever You need here... 
    } 
    else { 

     $mycrumb[1] = str_replace("//","/",$mycrumb[1]); 
     $crumbs[] = "<a href=\"".$mycrumb[1]."\">".$mycrumb[0]."</a> > <a href=\"#\">Smile TRU</a>"; 
    } 
}

試試這個：

$crumbs = array(); 
$crumbs[] = "<a href=\"/\">Triple O Dental Laboratory</a>"; 

if (is_array($GLOBALS["cookie_crumbs"])) { 
    foreach($GLOBALS["cookie_crumbs"] as $mycrumb) { 
     if(end($GLOBALS["cookie_crumbs"] != $mycrumb)){ 
      $mycrumb[1] = str_replace("//","/",$mycrumb[1]); 
      $crumbs[] = "<a href=\"".$mycrumb[1]."\">".$mycrumb[0]."</a> > <a href=\"#\">Smile TRU</a>"; 
     } 
     else{ 
      $mycrumb[1] = str_replace("//","/",$mycrumb[1]); 
      $crumbs[] = "<a href=\"".$mycrumb[1]."\">".$mycrumb[0]."</a>"; 
     } 
    } 
} 

print "<div class=\"cookie_crumbs2\">\n"; 
print implode(" > ",$crumbs); 
print "</div>\n";
