正则表达式-用另一个字符串替换数字和字符串的组合

Question

I need to replace all occurrence of [any number] and [particular string] with a [replacement string]

For example if strings like 195 apples or 10 apples are found in a paragraph I need to replace this with 10 Oranges

Example paragraph: There are 195 apples in the first basket and 10 apples in the second basket.

After applying regex replace, I should get a result Result : There are 10 Oranges in the first basket and 10 Oranges in the second basket.

In Jquery i used

 myString.replaceAll("[(?i)string]", "anotherstring"); 

Need to do this in PHP as well as Jquery.

Can anyone please help me? Thanks

Answer 1

How about:

 var myString = 'There are 195 apples in the first basket and 10 apples in the second basket.'; myString = myString.replace("/(?i)\\d+\\s+apples\\b/g", "10 Oranges"); console.log(myString); 

Answer 2

Search \\d{1,}\\s+(apples)

Replace 10 Oranges

Answer 3

Try using the following regex :

(\d+\s(\w+))

** you can replace \\w+ with your desired string

see demo / explanation

JavaScript

 var str = "There are 195 apples in the first basket and 10 apples in the second basket."; var result = str.replace(/(\\d+\\s(\\w+))/ig, "10 Oranges"); console.log(result); 

PHP

$re = '/(\d+\s(\w+))/';
$str = 'There are 195 apples in the first basket and 10 apples in the second basket.';
$subst = '10 Oranges';
$result = preg_replace($re, $subst, $str);
echo $result;

Answer 4

This worked

PHP

$re = '/(\d+\s((apples\b|apple\b)+))/';
$str = '195 apples in the first basket and 0 apple but 1 applex';
$subst = '10 Oranges';
$result = preg_replace($re, $subst, $str);
echo $result;

JQuery

var text1 = "10 apples is good";
var rrr = "10 Oranges";
var str = "There are 195 apple in the first basket and 10 apples in the second basket.1 apple";
var result = str.replace(/(\d+\s((apples\b|apple\b)+))/ig,"10 Oranges");
console.log(result);
