Question

我希望将数组与字符串匹配，并将字符串中包含的城市名称替换为短划线（ - ）

例如：

$str = 'French Tuition In Newyork' OR $str = 'French Tuition Newyork';

$arrCity = array('Newyork', 'Washington');

我想替换上面的字符串，如下所示，

$str = 'French Tuition - Newyork' AND $str = 'French Tuition - Newyork';

因此，如果最后一个单词是城市，则应该用破折号（ - ）预先附加。要么如果最后一个单词是city，并且在最后一个单词是“IN”之前，则“IN”应该用短划线（ - ）替换。

Answer 1

供您参考。

<?php

//$str = 'French Tuition Newyork';
$str = 'French Tuition In Washington'; 
$arrCity = array('Newyork', 'Washington');
$in_str = 'In';

foreach ($arrCity as $key => $value) {
  $pos = strpos($str, $value);

  if($pos) {
     $pos2 = strpos($str, $in_str);

     if($pos2) 
       $temp_str = explode($in_str, $str);
     else 
       $temp_str = explode($value, $str);

     $result = $temp_str[0] . ' - ' . $value;
     echo $result;
  }

}
?>

Answer 2

<?php
$str = 'French Tuition Washington';
$arrCity = array('Newyork', 'Washington');
$cities = implode('|', $arrCity);
echo preg_replace("/(French Tuition).+({$cities})/", '$1 - $2', $str);
?>

Answer 3

你可以这样做。

<?php
$str = 'French Tuition In Newyork';
$str2 = 'French Tuition Newyork';
$arrCity = array('Newyork', 'Washington');
$temp = array();

$split = explode(" ", $str);
$lastword = $split[count($split)-1];
$beforeLastWord = $split[count($split)-2];

if(in_array($lastword, $arrCity)) {
  if(strtolower($beforeLastWord) === 'in') {
    $split[count($split)-2] = '-';
  }
  else {
    $split[count($split)-1] = '-';
    array_push($split, $lastword);
  }
}

echo implode(" ", $split);
?>

Answer 4

这是有效的;）

<?php
   $str = 'French Tuition In Washington'; 
   $str1 = 'French Tuition Newyork'; 
    function dash($string)
    {
       if (strpos($string,'In') !== false) 
       {
          echo str_replace('In','-',$string);
        }
        else
        {
          $arrCity = array('Newyork', 'Washington');
          foreach($arrCity as $city)
          {
            if(strpos($string,$city))
            {
              echo str_replace($arrCity,'- '.$city,$string);
            }
          }
        }
    }

  dash($str);
  dash($str1);
?>

输出

French Tuition - Washington
French Tuition - Newyork
