从PHP中的字符串中提取地址的一部分

Question

I created a html form in which you can enter your street address in a single string. How can I extract the street number, street name and street type (crescent, road, street etc) in PHP? I am not sure of the length of the string they will enter and it might not extract the correct information.

Please kindly help as I am new in coding in PHP.

Here is my code below:

$address = $_POST["address"];

echo "Your address is: $address <br>";

$addressSubstring = substr($address,0 , 15);

echo "Address: $addressSubstring <br>";

$strNumber = substr($addressSubstring, 0, 2);

$strName = substr($addressSubstring, 2, 8);

$strType = substr($addressSubstring, 8, 15);

echo "Your street number is: $strNumber <br>";
echo "Your street name is: $strName <br>";
echo "Your street type is: $strType <br>"

Keeping in mind that road types are "crescent|road|street":

Using regular expressions can solve the issue:

<?php
$address = '43 Willow Street'; // $_POST["address"] or '35 Hanover Crescent & 52 Longford Road';

preg_match_all("/(\d+)(.+?)(crescent|road|street)/i", $example, $out_arr);

// $no_of_addresses_found = count($out_arr[0]); // in case of future improvements
$strNumber = $out_arr[1][0];     // 43
$strName = trim($out_arr[2][0]); // Willow
$strType = $out_arr[3][0];       // Street

echo "Your street number is: $strNumber <br>";
echo "Your street name is: $strName <br>";
echo "Your street type is: $strType <br>"
