The code was working:
$url = 'http://www.google.com/search?hl=en&tbo=d&site=&source=hp&q=upoznavanje';
$html = file_get_html($url);
preg_match_all('/(?<="><cite>).*?(?=<\/cite><div\ class=)/', $html, $output);
foreach ($output[0] as $link) {
$link ."<br>" ;
}
When I added echo $output[0], now I get 0, and nothing in $output[1].
var_dump works and print_r array is there, but how do I get unique values of each without foreach?
var_dump:
array(1) { [0]=> array(10) { [0]=> string(21) "https://www.elmaz.rs/" [1]=> string(47) "https://badoo.com/sr/upoznavanje/serbia/" [2]=> string(39) "https://serbiandating.com/?locale=sr_RS" [3]=> string(30) "https://www.lepoticaizver.com/" [4]=> string(22) "www.prvi-sastanak.net/" [5]=> string(122) "https://www.telegraf.rs/.../1878507-top-5-aplikacija-za-muvanje-ovo-su- najbolji-sajtovi-za-upoznavanje-i-dejt-foto" [6]=> string(137) "https://www.telegraf.rs/.../1863749-dopisivala-sam-se-sa-muskarcinama-na- sajtu-za-upoznavanje-uh-kakve-sam-sve-ponude-dobila-foto" [7]=> string(24) "https://www.iskrica.com/"
I found how to do that with extracting single data from array without loop:
print_r($output[0][0]);

I'm trying to convert a string into a multidimentional array.
I've found many answers online but they expect you to have array keys etc...
My String:
UserIds\n234234\n20053\n19928\n16325
I've tried the usual way:
$arr= array();
$arr = explode("\n", $string);
and i've also tried
$arr[] = explode("\n", $string);
but the result is always like this:
array(5) {
[0]=> string(7) "UserIds"
[1]=> string(6) "234234"
[2]=> string(5) "20053"
[3]=> string(5) "19928"
[4]=> string(5) "16325"
}
My Expected Result:
array(5) {
[0]=> array(1) { [0]=> string(7) "UserIds" }
[1]=> array(1) { [0]=> int(234234) }
[2]=> array(1) { [0]=> int(20053) }
[3]=> array(1) { [0]=> int(19928) }
[4]=> array(1) { [0]=> int(16325) }
}
One way to do it could be to map the response using array_map and wrap the items in an array:
$string = "UserIds\n234234\n20053\n19928\n16325";
$arr = array_map(function($x){return [$x];}, explode("\n", $string));
print_r($arr);

I want to loop through the following array.
array(2) {
[0]=> array(6) {
[0]=> string(10) "excel_id "
[1]=> string(12) "excel_name "
[2]=> string(11) "excel_email"
[3]=> string(13) "excel_address"
[4]=> string(12) "excel_giveby"
[5]=> string(16) "excel_accesories"
}
[1]=> array(6) {
[0]=> float(111)
[1]=> string(10) "sh1exname1"
[2]=> string(11) "sh1exemail1"
[3]=> string(12) "sh1exaddress"
[4]=> string(12) "sh1exgivenby"
[5]=> string(16) "sh1exaccesorries"
}
}
can anyone help me?
If you tried anything at all you should have found foreach.
this will loop through all of your array values.
You can simply loop through a multi-dimensional array by using a multi-dimensional foreach like this:
foreach($array as $parentValue)
{
foreach($parentValue as $childValue)
{
// your code
}
}
try this:
foreach ($main_array as $outer_entry){
foreach($outer_entry as $entity){
print_r($entity);
}
}
Kinda of a noobie in PHP and Regex, I receive the following from a web service:
test:002005#1111#333333#;10205#2000#666666#;002005#1111#55555#;
The above line is a sequence of 3 numbers which repeats 3 times. I would like to get the 3rd number of each sequence and I believe the best course (besides 3000 explodes) would be preg_match_all but I am having a tough time wrapping my mind around RegEx.
The end result should look like this:
Array
(
[0] => 333333
[1] => 666666
[2] => 55555
)
Thanks in advance for any help.
if(preg_match_all('/.*?(?:\d+#){2}(\d+)#;/',$s,$m)) {
print_r($m[1]);
}
http://ideone.com/99M9t
or
You can do it using explode as:
$input = rtrim($input,';');
$temp1 = explode(';',$input);
foreach($temp1 as $val1) {
$temp2 = explode('#',$val1);
$result[] = $temp2[2];
}
print_r($result);
http://ideone.com/VH29g
Use the function explode()
<?php
$pizza = "piece1#piece2#piece3#piece4#piece5#piece6";
$pieces = explode("#", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2
?>
I don't remember exactly how the saying goes but...
"You have a problem and decide to use regular expressions... now you have two problems."
Your problem can easily be solved if we assume 'test:' isn't part of the actual string to be parsed.
<?php
$in = '002005#1111#333333#;10205#2000#666666#;002005#1111#55555#;';
function splitGroupsAndGetColumn($input, $groupSeparator, $columnSeparator, $columnIndex, $skipEmpty=true)
{
$result = array();
$groups = explode($groupSeparator, $input);
foreach($groups as $group)
{
$columns = explode($columnSeparator, $group);
if (isset($columns[$columnIndex]))
{
array_push($result, $columns[$columnIndex]);
}
else if (! $skipEmpty)
{
array_push($result, NULL);
}
}
return $result;
}
var_dump(splitGroupsAndGetColumn($in, ';', '#', 2));
Output:
array(3) {
[0]=>
string(6) "333333"
[1]=>
string(6) "666666"
[2]=>
string(5) "55555"
}
You could use preg_match_all for this task, which makes the task quite simple:
$a = "test:002005#1111#333333#;10205#2000#666666#;002005#1111#55555#;";
preg_match_all('/#(\d+)#;/', $a, $m);
print_r($m);
$m[1] contains the output, you want.
Reference: http://php.net/manual/en/function.preg-match-all.php
My version :)
The regex (\d+) means I want all that is a number one or more
php > $a = '002005#1111#333333#;10205#2000#666666#;002005#1111#55555#';
php > preg_match_all('/(\d+)/',$a,$matches);
php > var_dump($matches);

I'm posting an array of ids and want to loop over those values. I'm trying the following to populate an array with key/value pairs but it looks like the array is coming out empty.
$arr = array();
foreach($_POST['ids'] as $id)
{
$arr[$id] = GetStuff($id);
}
UPDATE: Looks like array was populated fine. I'm trying to return contents of array by doing echo json_encode($arr) but response is blank.
Here is output of var_dump($_POST);
array(1) {
["ids"]=>
array(18) {
[0]=>
string(6) "156795"
[1]=>
string(6) "156800"
[2]=>
string(4) "4292"
[3]=>
string(6) "796053"
[4]=>
string(6) "660520"
[5]=>
string(4) "4293"
[6]=>
string(4) "4287"
[7]=>
string(6) "488339"
[8]=>
string(6) "837701"
[9]=>
string(7) "1152093"
[10]=>
string(7) "1186434"
[11]=>
string(7) "1324432"
[12]=>

[13]=>
string(6) "144860"
[14]=>
string(5) "15065"
[15]=>
string(7) "1324434"
[16]=>
string(5) "13066"
[17]=>
string(4) "6969"
}
}
foreach($_POST['ids'] AS $i=>$id) {
//do stuff
}
Don't forget about quotes..
$arr = array();
foreach($_POST['ids'] as $id)
{
$arr[$id] = GetStuff($id);
}
Notice the tick marks around ids in $_POST.
This should work:
foreach($_POST['ids'] as $id)
{
$arr[$id] = $_POST['ids'][$id];
}
or even faster, if you are just wanting an array identical to the posted ids:
$arr = $_POST['ids'];
unless I am misunderstanding the question.

Not a regex problem.
$names = explode('#', $names);
$keep = array();
foreach ($names as $name)
{
if ((substr($name, 0, 1) == '!') && (substr($name, -6) == '12.JPG'))
{
$keep[] = $name;
}
}
Try using '/#\!([^_]+)_12.JPG/' instead. Also, you're using preg_match_all, right?
Example ..
<?php
$input = '(that long string you have)';
$matches = array();
preg_match_all('/#\!([^_]+)_12.JPG/', $input, $matches);
var_dump($matches);
Output (notice how $matches[0] contains all full matches, and $matches[1] contains all grouped (up to _12.JPG) matches) ..
