I get string:
$res = "RESULT: SUCCESS
NUMBER_TYPE: 0";
I want get "RESULT" and for this i use explode:
$arr = explode('\n\r', $res);
$result = trim(explode('RESULT:', $arr[0]));
But i get Arrayfalse
Tell me please how correctly get RESULT?
P.S.: result should been SUCCESS
You can use explode then preg_split
$arr = explode(':', $res);
$arr = preg_split('/\s+/', $arr[1]);
echo $arr[1];
You can also use this one with explode only.
$arr = explode("\n", $res);
$arr= explode(":", $arr[0]);
echo trim($arr[1]);
Trying Doing this
$arr = explode(':', $res);
$result = explode(' ', $arr[1]);
print_r($result[0]);
Try :
$ex = explode(":",$res);
$result = explode("\n",$ex[1]);
$result = $result[0];
echo trim($result); //echoes SUCCESS
Or :
$ex = explode("\n", $res);
$result = explode(":", $ex[0]);
$result = $result[1];
echo trim($result); //echoes SUCCESS
SUCCESS NUMBER_TYPE not SUCCESS ...which the OP doesnt want.
'\n' is "\n", not a line break.
The first comment to your answer is the solution. But - for any reason - if you want to get all the keys and values, you can use preg_match for each line. A quick example:
<?php
$res = "RESULT: SUCCESS
NUMBER_TYPE: 0";
$arr = explode("\n", $res);
foreach($arr as $line)
{
if(preg_match('/^([A-Z_]+):\s+?([a-zA-Z0-9_]+)$/', $line, $matches))
{
echo "Key: " . $matches[1] . " - Value: " . $matches[2] . "\n";
}
}
Output:
Key: RESULT - Value: SUCCESS
Key: NUMBER_TYPE - Value: 0
if (preg_match('/RESULT:\s*(\w+)/', $res, $match)) echo $match[1];- regular-expressions.infoexplode
