如何迭代循环内搜索字符串固定的关键字后的任何单词？ [英] How to iterate loop inside a string searching for any word aftera fixed keyword?

问题描述

假设我有一个像PHP的稻田，PHP的Pranav，PHP的部分，现在我有一个计数为3，现在我应该如何迭代循环在字符串瞄准字符串PHP后显示所有的名称？

好的这是字串 BEGIN IF（NEW.name！= OLD.name）然后插入到jos_menuaudit set menuid = OLD.id ，oldvalue = OLD.name，newvalue = NEW.name，field =name; END IF; IF（NEW.alias！= OLD.alias）THEN INSERT INTO jos_menuaudit set menuid = OLD.id，oldvalue = OLD.alias， newvalue = NEW.alias，field =alias; END IF; END 其中我搜索 IF（NEW。，并在此之后特殊的其他字符串不应该显示，因此无论何时在循环中，它发现 IF（NEW。我musr得到一个字旁边。并以这种方式一个数组应该准备好使用。

解决方案

使用 explode 和 substr ：

  $ str =PHP Paddy，PHP Pranav，PHP Parth; 
 $ ary = explode（'，'，$ str）; 
 foreach（$ ary as $ str）{
 echo substr（$ str，4）; 
} 
  

Suppose I have a sting as "PHP Paddy,PHP Pranav,PHP Parth", now i have a count as 3,now how should I iterate loop in the string aiming on string after "PHP " to display the all the names?

Alright This is the string "BEGIN IF (NEW.name != OLD.name) THEN INSERT INTO jos_menuaudit set menuid=OLD.id, oldvalue = OLD.name, newvalue = NEW.name, field = "name"; END IF; IF (NEW.alias != OLD.alias) THEN INSERT INTO jos_menuaudit set menuid=OLD.id, oldvalue = OLD.alias, newvalue = NEW.alias, field = "alias"; END IF; END" in which i am searching the particular word after " IF (NEW.", and after that particualar others strings should not b displayed, hence whenever in a loop it finds " IF (NEW." I musr get a word just next to it. and in this way an array should b ready for to use.

解决方案

Use explode and substr:

$str =  "PHP Paddy,PHP Pranav,PHP Parth";    
$ary = explode(',', $str);
foreach($ary as $str){
   echo substr($str, 4);
}
