PHP - Split string [duplicate]

This question already has answers here: PHP - split String in Key/开发者_JAVA技巧Value pairs (5 answers) Closed 11 months ago.

I want to split this string up into parts like "Source: Web", "Pics: 1" ... to use it within my website. From the "Lat:" and "Lon:" I need to extract just the numbers.

    <cap>
Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555
</cap>

What's the best way to do it? I read about explode() but I don't get it to work. Cheers

Here is a bit of code I whipped up using explode (DEMO)

<?php    
    $str = "Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555";
    $arr = explode(" | ", $str);
    foreach ($arr as $item){
        $arr2 = explode(": ", $item);
        $finalArray[$arr2[0]]=$arr2[1];
    }
    print_r($finalArray);
?>

RESULT

Array
(
    [Source] => Web
    [Pics] => 1
    [Frame] => 2
    [Date] => 4-25-2011
    [On] => App
    [Lat] => 51.2222
    [Lon] => 7.6555
)

USAGE

echo $finalArray['Lon']; //yields '7.6555'

Here's a ridiculous one-liner that should probably never be used, but it uses no loops (i hate loops). I also like to practice my REs

$str = 'Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555';
preg_match( sprintf( '~%s~', implode(array_map( function($val){ if ($val) return sprintf( '%1$s:\s(?P<%1$s>.*?)(?:(?:\s\|\s)|(?:$))', $val ); }, preg_split( '~:.*?(?:(?:\s\|\s)|(?:$))~', $str ) ) ) ), $str, $m );
print_r($m);

result

Array
(
    [Source] => Web
    [Pics] => 1
    [Frame] => 2
    [Date] => 4-25-2011
    [On] => App
    [Lat] => 51.2222
    [Lon] => 7.6555
)

$pieces = explode(' | ','Source: Web...'); //Rest of string in there.
$items = array();
foreach ($pieces as $piece) {
    $parts = explode(': ', $piece);
    $items[$parts[0]] = $parts[1];
}

---

$string = "Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555";
$pieces = explode("|", $string);
print_r($pieces);

---

$items = explode(' | ', "Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555");

foreach ($items as $item) {
   $new_data = explode(': ', $item);
   $my_array[$new_data[0]] = $new_data[1];
}

print_r($my_array);

Try this one. It will split them and create an associative array:

$string = 'Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555';
$list = explode('|', $string);
$assoc = array();
foreach($list as $part) {
    list($key, $val) = explode(':', $part);
    $assoc[trim($key)] = trim($val);
}

print_r($assoc);

---

$val =<<<END
<cap>
    Source: Web | Pics: 1 | Frame: 2 | Date: 4-25-2011 | On: App | Lat: 51.2222 | Lon: 7.6555
</cap>
END;

$bits = split("[:|]", $val);
$lat = trim($bits[11]);
$lon = trim($bits[13]);

You are correct. explode is the best function for this.
