In the following code, is it possible to spilt the Object $author where white space occurs ?
<?php
$url="http://search.twitter.com/search.rss?q=laugh";
$twitter_xml = simplexml_load_file($url);
foreach ($twitter_xml->channel->item as $key) {
$a = $key->{"author"};
echo $a;
}
?>
$split = explode(' ', (string) $key->{"author"}));
OR
$split = preg_split('/\s+/', (string) $key->{"author"}));
To split by # just take $split and run in loop
foreach($split as $key => $value) {
$eta = explode('#', $value);
var_dump($eta);
}
To check if string exist use strpos
foreach($split as $key => $value) {
if (strpos($value, '#') !== 0) echo 'found';
}
Use explode:
$array = explode(' ', $key->{"author"});
There is an explode function that can easily accomplish that. So, for example:
$a = $key->{"author"};
$author = explode(" ", $a);
$first_name = $author[0];
$last_name = $author[1];
Hope that helps.
Assuming you merely care to get 2 parts: email, and "friendly name" (cause people have 1 to n number of names).
<?php
$url="http://search.twitter.com/search.rss?q=laugh";
$twitter_xml = simplexml_load_file($url);
foreach ($twitter_xml->channel->item as $key) {
$a = $key->{"author"};
preg_match("/([^ ]*) (.*)/", $a, $matches);
print_r($matches);
echo "\n";
}
?>

I have a string
$str = "a,b,c,d,e";
And I want convert string as:
$str_convert = "'a','b','c','d','e'";
What should I do?
Try my solution:
<?php
$str = "a,b,c,d,e";
$arr = explode(',',$str);
foreach ($arr as &$value) {
$value = "'$value'";
}
$str_convert= implode(',', $arr);
echo $str_convert;
Like this:
$str = "a,b,c,d,e";
$items = split(",", $str);
$convert_str = "";
foreach ($items as $item) {
$convert_str .= "'$item',";
}
$convert_str = rtrim($convert_str, ",");
print($convert_str);
If you would like a different solution using functional programming coding style, here it is:
<?php
$str = 'a,b,c,d,e';
$add_quotes = function($str, $func) {
return implode(',', array_map($func, explode(',', $str)));
};
print $add_quotes(
$str,
function ($a) {
return "'$a'";
}
);
I'm having trouble using preg_match_all to split a string into key value pairs. An example of my string:
"%Title:Movie%Sortable%Writer:%Indexed:false%"
Where I expect results like:
$result['Title'] = 'Movie';
$result['Sortable'] = '';
$result['Writer'] = '';
$result['Indexed'] = 'false';
I can split the string using preg_match('/%/',$str,-1,PREG_SPLIT_NO_EMPTY); but it returns an indexed array. I need an associative array so that order is not important and I can use the key in a switch statement. What would be the correct regex to use in preg_match_all?
Try with:
$input = "%Title:Movie%Sortable%Writer:%Indexed:false%";
$output = array();
$data = explode('%', $input);
foreach ($data as $item) {
list($key, $value) = explode(':', $item);
$output[$key] = $value;
}
<?php
$arr = array();
$string = "%Title:Movie%Sortable%Writer:%Indexed:false%";
$d = explode('%', $string);
foreach($d as $item){
list($key,$value) = explode(':', $item);
$arr[$key] = $value;
}
print_r($arr);
?>
I got this
$description = '<p>text1</p><p>text2</p><p>text3</p><p>text4</p><p>textn</p>'
I want to remove only what comes after <p>text3</p>
My result would be:
$description = '<p>text1</p><p>text2</p><p>text3</p>'
My guess is that we need to use preg_replace with some regex but I can't manage to write a working one.
You could...
function str_occurance($needle, $haystack, $occurance) {
$occurance += 2;
$arr = explode($needle, $haystack, $occurance);
unset($arr[0]);
$arr = array_values($arr);
$key = count($arr) - 1;
unset($arr[$key]);
$str = $needle . implode($needle, $arr);
return $str;
}
Not the prettiest, but it works.
Edit: To use:
$description = '<p>text1</p><p>text2</p><p>text3</p><p>text4</p><p>textn</p>';
$split = '<p>';
$return = 3;
$new = str_occurance($needle, $description, $return);
echo $new; // returns <p>text1</p><p>text2</p><p>text3</p>
My data variable:
1=icon_arrow.gif,2=icon_arrow.gif,3=icon_arrow.gif
I need it to be grouped by the value after =, so in this case it should look like this:
$out = array('icon_arrow.gif' => '1, 2, 3');
The 'icon_arrow.gif' field need to be unique, and can't repeat.
How it can be done?
Initialize an array:
$array = array();
Explode the input by ,, store results as an array based on a sub-explode of it by =:
foreach(explode(',', $string) as $p)
{
list($i, $n) = explode('=',$p);
$array[$n][] = $i;
}
Implode then the result with ,:
foreach($array as &$v)
$v = implode(', ', $v);
unset($v);
Done.
Just for fun. With no special chars this should also work.
$str="1=icon_arrow.gif,2=icon_arrow.gif,3=icon_arrow.gif,4=x.gif";
$str = str_replace(',', '&', $str);
parse_str($str, $array);
$result = array();
foreach($array as $k=>$v)
$result[$v] = (isset($result[$v]) ? $result[$v] . ", " : "") . $k;
I have a string containing ; subdivided by , and would like to make an echo of a chosen value.
My string is $string='Width,10;Height,5;Size,1,2,3'
I want to make an echo of the Height value (echo result must be 5)
$parts = explode(';', $string);
$component = explode(',', $parts[1]); // [1] is the Height,5 portion
echo $component[1]; // 5
Or this:
$p = explode(';', $string);
$data = array();
foreach($p as $part) {
$split = explode(',',$part,2); //the 'Size' bit different that the rest. I assume 1,2,3 is the value for Size?
$data[$split[0]] = $split[1];
}
$what_you_want_to_find = 'Height';
echo $data[$what_you_want_to_find];
try this:
$attrs = explode(";", $string);
$attrHeight = "";
foreach ($attrs as $value) {
if (strpos($value, "Height") !== false)
$attrHeight = explode(",", $value);
}
echo $attrHeight;
