使用PHP如何测试模式的字符串然后改变它?

在PHP中给出这个字符串:

$string = '/sometext?123#abc/moretext';

我如何测试模式“?123#abc /”的存在,它总是被“?”包围和“/”,但有不同的内部文本,可能包括任何文字和符号?模式之外的文本也将不同。我需要这样做:

if ($string includes pattern ?*/) {
  //load the inner value into a variable

  //then remove the entire patern including the leading "?" and trailing "/" and replace with a single "/"

}

我该怎么做?

<?php

$string = '/sometext?123#abc/moretext';
$pattern = '/\\?(.*?)\\//';

if( $pieces = preg_split($pattern, $string, Null, PREG_SPLIT_DELIM_CAPTURE)) {
    echo($pieces[1] . "\n");
    unset($pieces[1]);
    echo(implode("/", $pieces) . "\n");
}

?>

--output:--

~/php_programs$ php 1.php 
123#abc
/sometext/moretext

试试这个

$s = '/sometext?123#abc/moretext';
$matches = array();
$t = preg_match('#\?(.*?)\/#s', $s, $matches);
if($matches[1])
   echo "match";
else
   echo "not";

输出

match
