我需要删除搜索字符串的下一个单词..我有像数组一样的搜索数组(‘aa’,’bb’,’é’);
这是我的段落’你好,这是测试段aa 123测试bb 456′.
在本段中,我需要删除123和456.
$pattern = "/\bé\b/i";
$check_string = preg_match($pattern,'Hello, this is a test paragraph aa 123 test é 456');
如何获得下一个字?请帮忙.
最佳答案 这是我的解决方案:
<?php
//Initialization
$search = array('aa','bb','é');
$string = "Hello, this is a test paragraph aa 123 test bb 456";
//This will form (aa|bb|é), for the regex pattern
$search_string = "(".implode("|",$search).")";
//Replace "<any_search_word> <the_word_after_that>" with "<any_search_word>"
$string = preg_replace("/$search_string\s+(\S+)/","$1", $string);
var_dump($string);
将“SEARCH_WORD NEXT_WORD”替换为“SEARCH_WORD”,从而消除“NEXT_WORD”.
