str_replace

is there a simpler way of expressing this please?

php:
<a href="newsarticle.php?ID=<?php echo(str_replace(array(" ","!","?",",",".",";",":","'","/"),""$row_NewsRS['NewsTitle'])); ?>">



Do I need to list all the non standard characters (ie ! / , . ' @ etc) individually or is there a way of expressing it without having to list them out?

Also, with this is there a way of making upper case go to lower case?

Cheers

Jamie

so you want to only allows letters and numbers?
you could use a preg_replace() for that which takes a regular expression

php:
<?php echo(preg_replace("/[^A-Za-z0-9]/"""$row_NewsRS['NewsTitle'])); ?>



See this thread also:
showthread.php?10349055-Remove-non-standard-characters-from-string

you can convert upper case to lower case using strtolower():
function.strtolower.php

Thanks Jason

Is there a way to combine that that with replacing a space between words with _

What I have tried (and hasnt worked) is:

<?php echo(str_replace(array(" "),"_", (preg_replace("/[^A-Za-z0-9_]/", "", $row_NewsRS['NewsTitle'])))); ?>

you include the underscore in the preg_replace() function:
preg_replace("/[^A-Za-z0-9_]/"


dont include the underscore in the pregreplace function, you are replacing it with a blank there so it cannot be found in the result that the replace function is using.

but what i am trying to do is take something like this:

the cat sat on the mat!!!!

and make it into

the_cat_sat_on_the_mat

neither way is leaving the underscores in the sentence....

reverse the order so that your replacing the spaces with underscores directly on the recordset result, then using the preg_replace to strip other characters:

php:
<?php echo(preg_replace("/[^A-Za-z0-9_]/"""str_replace(array(" "),"_", ($row_NewsRS['NewsTitle'])))); ?>
