PHP函数删除字符串中某些字符之间的所有字符

我对此感兴趣function delete_all_between($char1, $char2, $string) ，它将在给定的$

string中搜索$ char1和$ char2，如果找到了该字符串，则从这两个字符之间的子字符串中清除$ string， $ char1和$

char2本身。

例：

$string = 'Some valid and <script>some invalid</script> text!';
delete_all_between('<script>', '</script>', $string);

现在，$ string应该只包含

'Some valid and  text'; //note two spaces between 'and  text'

有人有快速解决方案吗？

回答：

<?php
$string = 'Some valid and <script>some invalid</script> text!';
$out = delete_all_between('<script>', '</script>', $string);
print($out);
function delete_all_between($beginning, $end, $string) {
  $beginningPos = strpos($string, $beginning);
  $endPos = strpos($string, $end);
  if ($beginningPos === false || $endPos === false) {
    return $string;
  }
  $textToDelete = substr($string, $beginningPos, ($endPos + strlen($end)) - $beginningPos);
  return delete_all_between($beginning, $end, str_replace($textToDelete, '', $string)); // recursion to ensure all occurrences are replaced
}
