在php替换字符效率最高也是最简单字符替换函数str_replace($arr1,$arr2,$str)

实例一

str_replace("iwind", "kiki", "i love iwind, iwind said");
Copy after login

将输出 "i love kiki, kiki said"

结果

即将 原字符串中的所有"iwind"都替换成了"kiki".str_replace是大小写敏感的,所以对你不能设想用 str_replace("iwind", "kiki",...)替换原字符串中的"iwind". str_replace还可以实现多对一

用法

str_replace() 函数使用一个字符串替换字符串中的另一些字符。

语法

str_replace(find,replace,string,count)参数

find 必需。规定要查找的值。

replace 必需。规定替换 find 中的值的值。

string 必需。规定被搜索的字符串。

count 可选。一个变量,对替换数进行计数。

function strreplace($str){
      $str = strips教程lashes($str);
      $str = str_replace(chr(92),'',$str);
      $str = str_replace(chr(47),'',$str);
      $str = str_replace(chr(10).chr(13),"",$str);
      $str = str_replace(&#39;<&#39;,"&lt;",$str);      $str = str_replace(&#39;>&#39;,"&gt;",$str);
      $str = str_replace(&#39;;&#39;,";",$str);
      $str = str_replace(&#39;"&#39;,"“",$str);
      $str = str_replace("&#39;","‘",$str);
