I am looking for finding middle part of a string using starting tag and ending tag in PHP.
$str = 'Abc/[email protected]/1267890(A-29)';
$agcodedup = substr($str, '(', -1);
$agcode = substr($agcodedup, 1);
final expected value of agcode:
$agcode = 'A-29';
You can use preg_match
$str = 'Abc/[email protected]/1267890(A-29)';
if( preg_match('/\(([^)]+)\)/', $string, $match ) ) echo $match[1]."\n\n";
Outputs
A-29

Basically Regular expression says:
\( Open Paren literal( .. )[^)]+ Close Paren )\) Close Paren literalOh and if you really have your heart set on substr here you go:
$str = 'Abc/[email protected]/1267890(A-29)';
//this is the location/index of the ( OPEN_PAREN
//strlen 0 based so we add +1 to offset it
$start = strpos( $str,'(') +1;
//this is the location/index of the ) CLOSE_PAREN.
$end = strpos( $str,')');
//we need the length of the substring for the third argument, not its index
$len = ($end-$start);
echo substr($str, $start, $len );
Ouputs
A-29
And you can test this here

If it was me, I would benchmark both methods, and see which is faster.
May this helps to you.
function getStringBetween($str, $from, $to, $withFromAndTo = false)
{
$sub = substr($str, strpos($str,$from)+strlen($from),strlen($str));
if ($withFromAndTo) {
return $from . substr($sub,0, strrpos($sub,$to)) . $to;
} else {
return substr($sub,0, strrpos($sub,$to));
}
$inputString = "Abc/[email protected]/1267890(A-29)";
$outputString = getStringBetween($inputString, '(', ')');
echo $outputString;
//output will be A-29
$outputString = getStringBetween($inputString, '(', ')', true);
echo $outputString;
//output will be (A-29)
return $outputString;
}
