My string is like the following format:
$string = "name=xxx&id=11&name=yyy&id=12&name=zzz&id=13&name=aaa&id=10";
I want to split the string like the following:
$str[0] = "name=xxx&id=11";
$str[1] = "name=yyy&id=12";
$str[2] = "name=zzz&id=13";
$str[3] = "name=aaa&id=10";
How can I do this in PHP?
Try this:
$matches = array();
preg_match_all("/(name=[a-zA-Z0-9%_-]+&id=[0-9]+)/",$string,$matches);
$matches is now an array with the strings you wanted.
Update
function get_keys_and_values($string /* i.e. name=yyy&id=10 */) {
$return = array();
$key_values = split("&",$string);
foreach ($key_values as $key_value) {
$kv_split = split("=",$key_value);
$return[$kv_split[0]] = urldecode($kv_split[1]);
}
return $return;
}
$string = "name=xxx&id=11&name=yyy&id=12&name=zzz&id=13&name=aaa&id=10";
$arr = split("name=", $string);
$strings = aray();
for($i = 1; $i < count($arr), $i++){
$strings[$i-1] = "name=".substr($arr[$i],0,-1);
}
The results will be in $strings
I will suggest using much simpler term
Here is an example
$string = "name=xxx&id=11;name=yyy&id=12;name=zzz&id=13;name=aaa&id=10";
$arr = explode(";",$string); //here is your array
Any surgery conducted on this malformed querystring may potentially corrupt data.
If you know that the input will not have = in the key name or values, then you can correct the querystring by injecting [] between each key name and the equals sign, then parse it normally and transpose if you wish.
Code: (Demo)
parse_str(str_replace('=', '[]=', $string), $array);
var_export(array_map(fn($name, $id) => get_defined_vars(), $array['name'], $array['id']));
Output:
array (
0 =>
array (
'name' => 'xxx',
'id' => '11',
),
1 =>
array (
'name' => 'yyy',
'id' => '12',
),
2 =>
array (
'name' => 'zzz',
'id' => '13',
),
3 =>
array (
'name' => 'aaa',
'id' => '10',
),
)
If this isn't strict enough, you can tighten the replacement process to explicitly nominate name and id keys.
parse_str(preg_replace('/\b(name|id)\K(?==)/', '[]', $string), $array);
Ideally, if you have control of the form fields which are producing this submission payload, you should most simply add [] the the fields' name attributes (<input type="text" name="name[]"> and <input type="text" name="id[]">) or otherwise correct the process that is creating key collisions in the payload.
If you want to do what you asked, nothing more or less , that's explode('&', $string).
If you have botched up your example and you have a HTTP query string then you want to look at parse_str().
name and id
