PHP如何删除字符串中的单词？

Question

Output:

GUJARAT

String Format

State Name (State Code)

I want to remove state code with parentheses. How can I do this by using regex in PHP?

Answer 1

You can try this

(?<=\s)(\(.*\))

Explanation

• (?<=\\s) - Positive look behind. Matches \\s (a white space).
• (\\(.*\\)) - Matches ( some random text)

Demo

Answer 2

Using RegEx

$text="GUJARAT (24)"
$statename=preg_replace("/\([^)]+\)/","",$text);

Answer 3

Try this one too.

 $text="GUJARAT (24)";
 $statename= preg_replace("/[(][0-9]*[)]/","",$text);
 echo $statename;

Answer 4

In case you don't want to use regex you can also use simple strpos and substr.
This is a lighter way to do it than using regex (less meory useage).
The code finds the ( and removes everything one step behind and forward.

$arr = ["GUJARAT (24)", "State Name (State Code)"];

foreach($arr as $val){
    echo substr($val, 0, strpos($val, "(")-1) . "\n";    
}
// GUJARAT
// State Name
