如何從數組中的每個值中刪除此子字符串？

Question

我試圖使用str_replace從鏈接數組中刪除這個小塊。這是我迄今爲止...

foreach ($link_body as $key => $unfinished_link) 
{ 
    // take that non-link piece off the end of each link 
    if (stripos($unfinished_link, '">') !== false) 
    { 
     str_replace('">',"", $unfinished_link); 
    } 
    else { 
     echo "<font color='#00FF66'>$unfinished_link</font><br>"; 
    } 
} 

我一直得到的結果是這樣的

我試着刪除'">'部分。我錯過了什麼？ THX

Answer 1

您需要分配更換完成的變化：

參考&

foreach ($link_body as $key => &$unfinished_link) { 
    // take that non-link piece off the end of each link 
    if (stripos($unfinished_link, '">') !== false) { 
     $unfinished_link = str_replace('">',"", $unfinished_link); 
     echo $unfinished_link; 
    } else { 
     echo "<font color='#00FF66'>$unfinished_link</font><br>"; 
    } 
} 

或

foreach ($link_body as $key => $unfinished_link) { 
    // take that non-link piece off the end of each link 
    if (stripos($unfinished_link, '">') !== false) { 
     $link_body[$key] = str_replace('">',"", $unfinished_link); 
    } else { 
     echo "<font color='#00FF66'>$unfinished_link</font><br>"; 
    } 
}

<?php 

    foreach ($link_body as $key => $unfinished_link) 
    { 

    if (stripos($unfinished_link, '">') !== false) 
     echo str_replace('">',"", $unfinished_link);  // echo it 

    else 
     echo "<font color='#00FF66'>$unfinished_link</font><br>"; 

    } 

?> 

OR

<?php 

    foreach ($link_body as $key => $unfinished_link) 
    { 

    if (stripos($unfinished_link, '">') !== false) 
     $new_link[] = str_replace('">',"", $unfinished_link); //get all the modified in array 

    else 
     echo "<font color='#00FF66'>$unfinished_link</font><br>"; 

    } 

    var_dump($new_link); 

?>
