这篇文章主要介绍了PHP实现删除字符串中任何字符的函数,涉及php针对字符串的遍历与截取操作技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了PHP实现删除字符串中任何字符的函数。分享给大家供大家参考。具体如下:

function delStr($start, $end, $orgenStr) 
{ 
  //读取要删除字符位置的前一部分字符串,并赋值给$temp  
  //strpos读取字符第一次出现的位置  
  //substr读取指定开始与结束位置的子字符串  
  //echo $before."—". $last;  
  $temp=$orgenStr; 
  while(strpos($temp, $start) && strpos($temp, $end)){ 
  $temp=substr($temp, 0, strpos($temp, $start)).substr($temp,strpos($temp, $end)+strlen($end));; 
  //读取要删除字符位置的后一部分字符串,然后将前后部分连接,并赋值给$temp  
  //返回最后是字符串  
  } 
  return $temp; 
} 
//应用实例  
$a="aaaa12345678bbbbtttttttttttttttttttttaaaa12345678bbbb 
kkkkkkkkkkkkaaaa12345678bbbbttttttttttttttttttttt"; 
$b="1234"; 
$c="5678"; 
echo delStr($b,$c,$a);
Copy after login

输出为:

aaaabbbbtttttttttttttttttttttaaaabbbbkkkkkkkkkkkkaaaabbbbttttttttttttttttttttt

PS:

一般应用在1234和5678中间有动态内容,可以批量地删除

update:加入了循环删除,可以删除所有符合条件的字符串 .
