PHP implements a function that deletes any character in a string _php tips

The example in this article describes the PHP implementation function that deletes any character in the string. Share to everyone for your reference. Specifically as follows:

function Delstr ($start, $end, $orgenStr) 
{/ 
  /Read the first part of the string to delete the character position, and assign to the $temp  
  //strpos the position where the read character is to appear for the second time  
  Substr reads the substring//echo $before that specifies the start and end positions  
  . —". $last;  
  $temp = $orgenStr; 
  while (Strpos ($temp, $start) && Strpos ($temp, $end)) { 
  $temp =substr ($temp, 0, Strpos ($temp, $start)). substr ($temp, Strpos ($temp, $end) +strlen ($end)) 
  Reads the latter part of the string to remove the character position, and then joins the front and rear parts and assigns the value to $temp  
  //Returns the string at the end 
  $temp; 
Application instance  
$a = "aaaa12345678bbbbtttttttttttttttttttttaaaa12345678bbbb 
Kkkkkkkkkkkkaaaa12345678bbbbttttttttttttttttttttt "; 
$b = "1234"; 
$c = "5678"; 
Echo delstr ($b, $c, $a); 

The output is:

Aaaabbbbtttttttttttttttttttttaaaabbbbkkkkkkkkkkkkaaaabbbbttttttttttttttttttttt

Ps:

General applications in the middle of 1234 and 5678 have dynamic content, can be deleted in bulk

Update: A circular deletion was added to delete all eligible strings.
