str_replace how to

Well i have a list in a txt with some 100ds rows containg a number with 3 digits and a word. I want to remove the number from the list. So i create a script php and i inport all the rows in an array and then i go with str_replace to change the array but it doesnt work can anyone helpme with this?

$keyword[$i] = "121 keyword1"
$keyword[$i] = str_replace("[0-9]+", " ", $keyword[$i]);

I want to take only $keyword[$i] = "keyword1"

Can anyone helpme with this?

 

str_replace doesn't support regular expressions.

Check out www.php.net/preg_replace

Hope that helps,

Jay

 

Untested but should probably work

$keyword[$i] = ereg_replace("[0-9]+", " ", $keyword[$i]);

Code (markup):

 

you can this using this pseudocode

get the list and convert them into an array
loop through the list, us regex to take out the numbers
rewrite the results into a new file

 

I did that it works but its a little bit noob
Any suggestions?

$keyword[$i] = str_replace(array("1", "2", "3", "4", "5", "6", "7", "8", "9", "0"), "", $keyword[$i]);
$keyword[$i] = ucfirst(trim($keyword[$i]));

 

Well, if you want to go that way ...

$keyword[$i] = str_replace(range(0, 9), "", $keyword[$i]);
$keyword[$i] = ucfirst(trim($keyword[$i]));

PHP:

... is an easier implementation (but the same).
