suppose i have a set of strings formatted in a way:
$string1 = "(substring1) Hello";
$string2 = "(substring2) Hi";
how do i get the inside of '()' as a single string. I know this is possible by using:
$substring = explode( ")",$string1 );
but then i'm left with $substring[0] containing "(substring", and $substring[1] containing the rest. Is there a fast wat to get the inside of '()'? thanks i know it's a no brainer question.
explode might need a workaround because ( and ) are different. A simple regex will get the job done.
$string1 = "(substring1) Hello";
preg_match('#\((.*?)\)#', $string1, $match); // preg_match_all if there can be multiple such substrings
print $match[1];
Well, if you want to keep the explode, do this with your substring[0]:
$substring[0] = substr($substring[0],1);
this will return you the portion after "(".
Else, use a regular expression to match what you need!
Edit:
Check the above answer to see the regular expression solution, this guy provided you a great way to solve your problem! :]
If you want to use explode to do this job:
<?php
$string1 = "(substring1) Hello";
function between($delimiter1, $delimiter2, $subject)
{
$arr = explode($delimiter2, $subject);
if (!$arr || empty($arr) || count($arr) == 1)
{
return '';
}
$oldStr = trim(array_shift($arr));
$arr = explode($delimiter1, $oldStr);
if (!$arr || empty($arr))
{
return '';
}
return trim(array_pop($arr));
}
$result = between('(', ')', $string1);
echo $result, "\n";
But I suggest you use preg_match function, which is use regular expression to match string, more powerful and complicated:
<?php
$string1 = "(substring1) Hello";
$pattern = '/\((.*?)\)/';
$match = array();
preg_match($pattern, $string1, $match);
echo $match[1], "\n";
more powerful and complicated:: Is that really more complicated? That regex seems so simple as compared to that complicated explode code
explodeis used when you want to split a string into multiple parts. What you want here is to extract one string from another string according to a certain pattern. Thuspreg_match(_all)is the way to go. Hanky Panky's answer is exactly how I would have solved this.
