用数组值替换分隔符之间每次出现的文本（在php中）

我要替换两次之间的每一次事件

{{

及

我想用符号{{}内的旧文本来选择新的， 我有一个数组：

$var["blue"]="ocean";
$var["red"]="fire";
$var["green"]="forest";

案文可以是：

people loves {{blue}} looks {{red}} and enjoy {{green}}

应该成为

people loves ocean looks fire and enjoy forest

我尝试了preg_替换，但没有结果：

function replaceTags($startPoint, $endPoint, $newText, $source) { 
    $var["blue"]="ocean";
    $var["red"]="fire";
    $var["green"]="forest";

    return preg_replace('#('.preg_quote($startPoint).')(.*)('.preg_quote($endPoint).')#si', 'IDONT-KNOW-WHAT-PUT-HERE', $source);
}

尝试：

这是PHP函数的完美示例：

我也会像axiac一样使用

preg\u replace\u callback

，不过，这里有一个简单的方法来处理它

<?php

// SET OUR DEFAULTS
$var["blue"]="ocean";
$var["red"]="fire";
$var["green"]="forest";

$string = 'people loves {{blue}} looks {{red}} and enjoy {{green}}';


// MAKE A CALLBACK FUNCTION THAT WILL REPLACE THE APPROPRIATE VALUES
$callback_function = function($m) use ($var) {
    return $var[$m[2]];
};


// RUN THE PREG_REPLACE_CALLBACK - CALLING THE FUNCTION
$string = preg_replace_callback('~(\{\{(.*?)\}\})~', $callback_function, $string);


// DYNAMITE
print $string;

你能告诉我们你试过什么吗？当然：函数替换标签（$startPoint，$endPoint，$newText，$source）{$var[“blue”]=“ocean”；$var[“red”]=“fire”；$var[“green”]=“forest”；return preg_replace（'.'.''preg_quote（$startPoint.））（'.*）（'.preg"endPoint.'.'.'.'.''）\si'，idon-KNOW-KNOW-what-PUT-HERE，$source）}将此添加到question@Thamizhan我刚做了，你能告诉我们你试过什么吗？当然：函数替换标签（$startPoint，$endPoint，$newText，$source）{$var[“blue”]=“ocean”；$var[“red”]=“fire”；$var[“green”]=“forest”；$var[“green”]=“forest”；return preg_replace（'.''（'..preg_quote（$startPoint.））（.*）（.*）（'.preg).$endPoint.）#si'，'IDONT-KNOW-WHAT-PUT-HERE'，$source）；}将此添加到question@Thamizhan我刚做过，数组$var[]来自一个数据库，非常长，我只想替换文本显示的单词数组$var[]来自一个数据库，非常长，我只想替换文本显示的单词
