Does anyone know what the regex to get the following result:
Hello world, Another day to die. => Hello world
I'm trying the following expression:
/^.*,/
But the result is 'Hello world!'
I want to ignore the last character (!). Can anyone give me a hand?
Best regards.
Use a positive lookahead:
/^.*?(?=,)/
Example use:
preg_match('/^.*?(?=,)/', "Hello world, Another day to die.", $matches);
echo "Found: {$matches[0]}\n";
Output:
Found: Hello world
Along with @acdcjunior's answer, here are a few alternatives:
"/^.*?(?=,)/" // (full match)
"/^(.*?),/" // (get element 1 from result array)
"/^[^,]+/" // (full match, bonus points for matching full string if there is no comma)
explode(",",$input)[0] // PHP 5.4 or newer
array_shift(explode(",",$input)) // PHP 5.3 and older
substr($input,0,strpos($input,","))
There are many ways to achieve this ;)
This is another one,
$str = 'Hello world, Another day to die';
preg_match('/[^,]+/', $str, $match);
Use the following :
/^[\w\s]+/
Use this, that only checks letters:
/^[a-z]+ [a-z]+/i
or without regex:
$res = split(",", $string, 2)[0];
!.
