[Solved] Match strings starts and end with particular character in a String using PHP? [closed]

by


I see 3 ways (I’m not sure about which one has the best perfs, but I will bet on the last procedural way):

  1. Using the json_decode function, you will get an array from your string and then just iterate over it to get your data
  2. Using regexp, see an example here with pattern /subdomain:(.*?),.*?comment:(.*?),/

  3. Using a procedural function, like :

    $subdomains = [];
$comments = [];

$subdomainLen = strlen('subdomain:');
$commentLen = strlen('comment:');

$str="{item_type:a,custom_domain:"google.com",subdomain:analytics,duration:324.33, id:2892928, comment:goahead,domain_verified:yes}, {item_type:b,custom_domain:"yahoo.com",subdomain:news,comment:awesome,domain_verified:no}, {item_type:c,custom_domain:"amazon.com",subdomain:aws,width:221,image_id:3233,height:13, comment:keep it up,domain_verified:no}, {item_type:d,custom_domain:"facebook.com",subdomain:m,slug:sure,domain_verified:yes}";

// While we found the 'subdomain' pattern
while(($subdomainPos = strpos($str, 'subdomain')))
{
    // Removes all char that are behind 'subdomain'
    $str = substr($str, $subdomainPos + $subdomainLen);

    // Retrieves the subdomain str and push to array
    $subdomains[] = substr($str, 0, strpos($str, ','));

    // If pattern 'comment' exists, do the same as before to extract the comment
    if($commentPos = strpos($str, 'comment'))
    {
        $str = substr($str, $commentPos + $commentLen);
        $comments[] = substr($str, 0, strpos($str, ','));
    }
}
