    (PHP 5, PHP 7, PHP 8)

    介绍

    DOMText 类继承自 DOMCharacterData，表示 DOMElement 或 DOMAttr 的文本内容。

    DOM 的文本替换函数。

    <?php
    function domTextReplace( $search, $replace, DOMNode &$domNode, $isRegEx = false ) {
    if (     $domNode->hasChildNodes() ) {
    $children = array();
    // 由于循环遍历正在修改的 DOM 是个坏主意，因此我们准备一个数组：
    foreach ( $domNode->childNodes as $child ) {
    $children[] = $child;
    }
    foreach (     $children as $child ) {
    if (     $child->nodeType === XML_TEXT_NODE ) {
    $oldText = $child->wholeText;
    if (     $isRegEx ) {
    $newText = preg_replace( $search, $replace, $oldText );
    } else {
    $newText = str_replace( $search, $replace, $oldText );
    }
    $newTextNode = $domNode->ownerDocument->createTextNode( $newText );
    $domNode->replaceChild( $newTextNode, $child );
    } else {
    domTextReplace( $search, $replace, $child, $isRegEx );
    }
    }
    }
    }
