PHP：如何在数组中删除字符串的某些部分

Question

I have this array

$address[] =  $row['name'].",".$row['locality_name'].",".$row['city_name']

The output is

Ashirwad Estate, Goregaon (w), Mumbai

I want to remove the (w) string from the output

How should I use a function with $row['locality_name'] to trim/remove that?

Answer 1

This is a more general answer

$row['locality_name'] = preg_replace("/\(.*\)/", "", $row['locality_name']);

or better

$address[] =  sprintf(
    "%s,%s,%s",
    $row['name'],
    preg_replace("/\(.*\)/", "", $row['locality_name']),
    $row['city_name']
);

Regex explanation

\( // escapes open bracket
.* // matches every char from zero to infinite times
\) // escapes closing bracket

Answer 2

$toRemove = array("(w)","(W)","(West)","(west)");
$row['locality_name'] = str_replace($toRemove, "", $row['locality_name']);

Answer 3

You can use preg_replace with the following regex

\s*(\([^)]+\)|\-\w+)

So your code looks like as

echo preg_replace("/\s*(\([^)]+\)|\-\w+)/","","Ashirwad Estate, Goregaon (w), Mumbai");
