Question

示例字符串：

AAAAAA BBBBB CCCCCCC

输出：

AAAXXX BBXXX CCCCXXX

我需要隐藏每个最后3个单词的字符。我试过str_replace但我无法做到。谢谢你的帮助

$replacement = "***"; 
if (stripos($name, ' ') !== false) { 
$star = substr($name, 0, -3).$replacement;
}

我尝试了这个，但代码只隐藏了最后一个单词的3个字符。我需要每一个字。感谢

Answer 1

您需要拆分字符串，替换最后三个字符，然后重新组合它。

$replacement = "***"; 

// break your string into an array based on the spaces
$temp = explode(' ', $name) ;

// our temporary name
$newName = '' ;
// loop through each part of the original name
foreach($temp as $section) {
    // append our modified string along with a space
    $newName .= substr($section, 0, -3).$replacement . ' ' ;
}

// set $name = $newName without the trailing space
$name = substr($newName,0,-1) ;

Answer 2

$replacement = "***"; 
$star = "";
$pieces = explode(" ", $name);
foreach ($pieces as $piece){
    $star .= substr($piece, 0, -3).$replacement." ";
}

如果您有一个句子，那么您可以使用空格对其进行切片并调用此函数，最后重新创建该句子。
