php 字符串替换的方法_PHP
这几天,工作中遇到一个小问题,有一内容类型的字段存储的是语言,因为这写数据是用Excel导入做的,所以为了处理简单,很多的语言就用逗号分隔,把所有语言做一个字符串,这样存入的时候就简单的多。但是由于当初数据质量的问题,有一部分“Chinese”是 “Mandarin Chinese”,现在需要把所有的“Mandarin Chinese”改为“Chinese”。
这就需要把一个字符串中的部分字符串替换掉。对于这样的问题,一般就是用正则表达式来做替换,或者使用PHP的一些替换的方法,这样做的话感觉很比较麻烦,时间又比较紧,所以就想了这样一个懒人办法,使用explode函数,把要替换的字符串做为分割符号,然后把两个数组元素中间接上要换成的字符串,然后UPDATE一下就行了。
复制代码 代码如下:
function replace(){
$sql = db_query("SELECT field_languages_value,nid FROM {content_type_company_profile} WHERE
field_languages_value like '%Mandarin Chinese%'");
while($result = db_fetch_object($sql)){
$a = explode("Mandarin Chinese",$result->field_languages_used_value);
$b = $a[].'Chinese'.$a[1];
db_query("UPDATE content_type_company_profile SET field_languages_used_value = '%s' WHERE nid = %
d",$b,$result->nid);
}
}
?>
