PHP將單詞中的多個部分更改為預定義的值

Question

我正在嘗試將動態內容添加到HTML以創建動態電子郵件模板。

所以在我的HTML中

    $html = '<b>Its a html {name} content email {email} here</b>';

我想將HTML中的{name}和{email}的值替換為

$arraydata = ["name"=>"Allan","email"=>"al@al.com"];

因此，我該如何進行操作，以便最終的HTML附加到HTML正文中

'<b>Its a html Allan content email al@al.com here'

我努力了

$newHtml = "";
foreach ($keyvals as  $key=>$val){
        //itereate through html file and replace keys with values
        //am stuck on how to replace all keys and create the above.
        //the keys above can be many 
    }
return $newHtml;

Answer 1

我將這樣進行：

$html = '<b>Its a html {name} content email {email} here</b>';
$arraydata = ["name"=>"Allan","email"=>"al@al.com"];

foreach ($arraydata as $key => $value) {
    $html = str_replace('{' . $key . '}', $value, $html);
}

return $html;

返回值為：

"<b>Its a html Allan content email al@al.com here</b>"

Answer 2

您可以使用以下代碼，如果出現多個占位符，則將替換以下代碼：

var replaceAll = function(string, replacingItem, replaceWith) {
   return string.toString().replace(new RegExp(replacingItem, 'g'), replaceWith);
};

$html = '<b>Its a html {name} content email {email} here</b>';
$arraydata = ["name"=>"Allan","email"=>"al@al.com"];

foreach ($arraydata as $key => $value) {
    $html = replaceAll($html, '{' . $key . '}', $value);
}

return $html;

希望對您有幫助

在這種情況下，我會

    $arraydata = ["name"=>"Allan","email"=>"al@al.com"];
    echo $html = '<b>Its a html '. $arraydata['name'].' content email '. $arraydata['email'].' here</b>';

輸出：此處是html Allan內容的html al@al.com電子郵件
