如何将字符串转换为特定的数组

Question

使用 PHP，如何转换此字符串：

$str = "Lorem ipsum dolor sit amet 00541000004UDewAAG consectetur adipiscing elit 00541000003WKoEAAW  eiusmod tempor incididunt 00541000003WKmiAA";

进入这样的数组：

$messageSegments = [
 ["type" => "Text", "text" => "Lorem ipsum dolor sit amet "], 
 ["type" => "Mention", "id" => "00541000004UDewAAG"], 
 ["type" => "Text", "text" => "consectetur adipiscing elit"], 
 ["type" => "Mention", "id" => "00541000003WKoEAAW"], 
 ["type" => "Text", "text" => "eiusmod tempor incididunt"], 
 ["type" => "Mention", "id" => "00541000003WKmiAA"], 
];

类型 "Mention" 始终采用这种格式：“00541000003WKoEAAW”，它是 Salesforce ID 而其他所有内容都是常规文本..

感谢任何帮助。

你可以使用分解函数http://php.net/manual/en/function.explode.php

     $str = "Lorem ipsum dolor sit amet 00541000004UDewAAG consectetur adipiscing elit 00541000003WKoEAAW  eiusmod tempor incididunt 00541000003WKmiAA";
    $array = explode(' ', $str);
    $generated = array();
     $y = "";
    for($x= 0; $x < sizeOf($array); $x++){
        if (substr($array[$x], 0, 3) != '005') {
       $y .= ' ' . $array[$x]; //CONCAT WORDS
     } else {
    $temp = array("type" => "Text", "text" => $y); //create the text array
    $temp2 = array("type" => "Mention", "id" => $array[$x]); //create the id array
       array_push($generated, $temp, $temp2); //then push it
     $temp = array(); //make array null
         $temp2 = array(); 
          $y = null; //and null
     }
   }
   print_r($generated);

<?php

$str = "Lorem ipsum dolor sit amet 00541000004UDewAAG consectetur adipiscing elit 00541000003WKoEAAW eiusmod tempor incididunt 00541000003WKmiAA";

$startWith = '005';

$exploded = explode(' ', $str);
$result = [];
$lastIndex = 0;

foreach ($exploded as $index => $word) {
    if (strpos($word, $startWith) === 0) {
        $textExploded = array_filter(array_slice($exploded, $lastIndex, $index - $lastIndex));
        $result = array_merge($result, [
            ['type' => 'Text', 'text' => implode(' ', $textExploded)],
            ['type' => 'Mention', 'id' => $word]
        ]);

        if (isset($exploded[$index +1])) {
            $lastIndex = $index + 1;
        }
    }
}

//var_dump($result);

我不得不使用 preg_split() + 组合两个数组。这解决了文本被截断的问题 - 如果 ID 位于字符串的开头等。

    $ids = [];
    $words = [];
    $final = [];

    $pattern = '/005[a-zA-Z|0-9]{15}/'; 
    $exploded = explode(' ', $text); 

    //get all the mention ids from new text
    foreach ($exploded as $index => $word) {
        if(preg_match($pattern, $exploded[$index])){
            //replace period or comma
            $id = str_replace(',','',str_replace('.','',$exploded[$index])); 
            array_push($ids,$id);
        }
    } 
    //get words array
    $words = preg_split($pattern, $text,-1, PREG_SPLIT_NO_EMPTY); 

    //find which is first: id or words
    $isIdFirst = preg_match('/^005/', $text); //if str starts with 005

    if($isIdFirst){
        for($x=0; $x < count($ids); $x++) {  
           array_push($final, ['type'=>'Mention','id'=>$ids[$x]]);
           if(isset($words[$x])){
                array_push($final, ['type'=>'Text', 'text'=>$words[$x]]);
           }
        }
    }else{
        for($x=0; $x < count($words); $x++) {  
            array_push($final, ['type'=>'Text', 'text'=>$words[$x]]);
            if(isset($ids[$x])){
                array_push($final, ['type'=>'Mention','id'=>$ids[$x]]);
            }
         }
    }  
    var_dump($final);
