Question

我开始学习php。我有一个数组：

array (size=24)
0 => string 'Paris, 458 boulevard Saint-Germain' (length=34)
1 => string 'Paris, 343 boulevard Saint-Germain' (length=35)
2 => string 'Marseille, 343 boulevard Camille Flammarion' (length=44)
3 => string 'Marseille, 29 rue Camille Desmoulins' (length=37)
4 => string 'Marseille, 1 chemin des Aubagnens' (length=34)
5 => string 'Paris, 12 rue des singes' (length=25)
6 => string 'Paris, 34 quai VoLtAiRe' (length=24)
7 => string 'Paris, 34 rue Voltaire' (length=23)
8 => string 'Lille, 120 boulevard Victor Hugo' (length=33)
9 => string 'Marseille, 50 rue Voltaire' (length=27)
10 => string 'Toulouse, 90 rue Voltaire' (length=26)
...

我想做的是将每个字符串元素解析为var：

$city = Lyon, Paris, Marseille...
$Number = 458, 343, 29..
$typeOfRoad = boulevard, rue, chemin, quaie...
$NameOfRoad = Saint-Germain, Camille Flammarion...

感谢。：）

Answer 1

foreach($input as $item) {
   // Parse string
   if (preg_match('/^(?P<city>\w+),\s+(?P<Number>\d+)\s+(?P<typeOfRoad>\w+)\s+(?P<NameOfRoad>.+)$/', $item, $m));
   // remove numerous keys
   $m = array_diff_key($m, array_flip(range(0,4)));
   // make vars
   extract($m);
   echo "$city  $Number  $typeOfRoad  $NameOfRoad\n";
}

Answer 2

试试这段代码:( $ array是包含所有项目的数组）

<?php
  foreach ($array as $item) {
    /* explode in 4 segments max */
    $segment = explode(' ', $item, 4);
    $city = $segment[0];
    $number = $segment[1];
    $typeOfRoad = $segment[2];
    $nameOfRoad = $segment[3];

    /* here you can use the variables before the next loop */
    [...]
  }
?>

编辑：此代码假设第一个，第二个和第三个变量没有空格，否则它对分隔符不可能。

Answer 3

$string = 'Lille, 120 boulevard Victor Hugo';

echo $city = substr($string, 0, strpos($string, ','));
echo PHP_EOL;
$parts = explode(" ", $string);
array_shift($parts);
echo $num = $parts[0];
echo PHP_EOL;
array_shift($parts);
echo $type = $parts[0];
echo PHP_EOL;
array_shift($parts);
echo $roadName = implode($parts, " ");
echo PHP_EOL;

Answer 4

您可以使用正则表达式。它应该类似于以下内容：

^（。），（\ d +）（\ S +）（。）
