Php 将子字符串替换为其编号'；事件

我想用子字符串的出现次数替换它，例如：

$text = "The dog is saying wooff wooff wooff wooff but he should say 
bark bark bark bark not wooff wooff wooff";

$newText = preg_replace('!\wooff+', 'wooff{$total}', $text);

结果应该是：

$newText = "The dog is saying wooff4 but he should say 
bark bark bark bark not wooff3";

如果您不希望捕获只出现一次的单词，可以修改回调函数，如下所示-

<?php

$text = "The dog is saying wooff wooff wooff wooff but he should say bark bark bark bark not wooff wooff wooff";

$newText = preg_replace_callback('|([a-zA-Z0-9]+)(\s\1)*|',function($matches){
                $same_strings = explode(" ",$matches[0]);
                if(count($same_strings) === 1){
                    return $matches[0];
                }
                return $same_strings[0] . count($same_strings);
            },$text);


echo "Old String: ",$text,"<br/>";
echo "New String: ",$newText;

您可以使用和

foreach

解决此问题
入门：

// Your string and the word you are searching
$str = "The dog is saying wooff wooff wooff wooff but he should say bark bark bark bark not wooff wooff wooff";
$search = 'wooff';

现在更换：

// Get the duplicates
preg_match_all('/(' . $search . '[\s]?){2,}/', $str, $duplicates);

// Foreach duplicates, replace them with the number of occurence of the search word in themselves
$new_str = $str;
foreach ($duplicates[0] as $dup) {
    $count = substr_count($dup, $search);
    $new_str = str_replace($dup, $search . $count . ' ', $new_str);
}
$new_str = trim($new_str);

输出：

echo $new_str;
// The dog is saying wooff4 but he should say bark bark bark bark not wooff3

好的，那么代码有问题吗？它会产生错误吗？它是否产生任何输出？简而言之，问题是什么？

woof-woof-bark-woof

看起来像什么？@riggsfuly-plase检查更新，我不确定preg_-replace是否有一些回调功能来显示我描述的preg-replace单词。@abracadver请检查更新again@vivek_23这正是我所想的：D！很好的工作伙伴

// Your string and the word you are searching
$str = "The dog is saying wooff wooff wooff wooff but he should say bark bark bark bark not wooff wooff wooff";
$search = 'wooff';

// Get the duplicates
preg_match_all('/(' . $search . '[\s]?){2,}/', $str, $duplicates);

// Foreach duplicates, replace them with the number of occurence of the search word in themselves
$new_str = $str;
foreach ($duplicates[0] as $dup) {
    $count = substr_count($dup, $search);
    $new_str = str_replace($dup, $search . $count . ' ', $new_str);
}
$new_str = trim($new_str);

echo $new_str;
// The dog is saying wooff4 but he should say bark bark bark bark not wooff3
