I have a PHP Script that users will enter a name like: Alex_Newton
,
However, some users will use a space rather than an underscore, so my question is:
How do I auto-replace spaces with Underscores in PHP?
This question is related to
php
$name = str_replace(' ', '_', $name);
Strtr
replaces single characters instead of strings, so it's a good solution for this example. Supposedly strtr
is faster than str_replace
(but for this use case they're both immeasurably fast).
echo strtr('Alex Newton',' ','_');
//outputs: Alex_Newton
I used like this
$option = trim($option);
$option = str_replace(' ', '_', $option);
You can also do this to prevent the words from beginning or ending with underscores like _words_more_words_, This would avoid beginning and ending with white spaces.
$trimmed = trim($string); // Trims both ends
$convert = str_replace('', '_', $trimmed);
you can use str_replace
say your name is in variable $name
$result = str_replace(' ', '_', $name);
another way is to use regex, as it will help to eliminate 2-time space etc.
$result= preg_replace('/\s+/', '_', $name);
As of others have explained how to do it using str_replace
, you can also use regex to achieve this.
$name = preg_replace('/\s+/', '_', $name);
This is part of my code which makes spaces into underscores for naming my files:
$file = basename($_FILES['upload']['name']);
$file = str_replace(' ','_',$file);
if you have a parameter $string
and want to replace it's apace to underscore(_).
$string = "Hello All.";
$newString = str_replace(' ', '_', $string);
output will be Hello_All.
Use str_replace:
str_replace(" ","_","Alex Newton");
Call http://php.net/str_replace: $input = str_replace(' ', '_', $input);
str_replace
- it is evident solution. But sometimes you need to know what exactly the spaces there are. I have a problem with spaces from csv file.
There were two chars but one of them was 0160 (0x0A0) and other was invisible (0x0C2)
my final solution:
$str = preg_replace('/\xC2\xA0+/', '', $str);
I found the invisible symbol from HEX viewer from mc (midnight viewer - F3 - F9)
