[random number]

So this only tells me the maximum number possible and doesn't let me set it.  Also will this maximum be the same for everyone or does it change between php versions?

 

Thanks

[word wrap in emails help needed]

Hello, I understand how wordwrap works in php and have used it well before.  However when I used wordwrap on a variable that is going to be emailed it puts the line breaks in well before it should.  The code is below.

 

$name = thisisaname

$email = thisisanemail

 

$text = "Account name:"."  ".$name."      "."Account email:"."  ".$email."\r"."\r";

 

$text = wordwrap($text,90,"\r");

 

If i change word wrap to 50 it wraps it after the word Account? any help.

[line breaks]

Thanks for the help.

[line breaks]

Thats exactly what I wanted.  Can you please tell me how "#[\r\n]{1,2}#" achieves what I wanted, what does the 1 and 2 do.

 

Will this code work for multiple lines in a row or is there a limit.

Thanks.

[line breaks]

but what if there are two line breaks as below:

 

$text = "this is just \r test \r\n\r\n text inside \n of text \n\r more text";

 

the echo should be:

 

this is just

test

 

text inside

of text

more text

 

but instead it is:

 

this is just

test

text inside

of text

more text

 

How can I keep the multiple line breaks?

[line breaks]

If i take the text

 

a

b

 

and put it into the function the one line break get doubled.

 

e.g  a\r\nb goes to a\r\n\r\nb what am I doing wrong.  I just want to convert all types of line breaks to \r\n and keep the number of line breaks.

[line breaks]

But would

 

$text = str_replace("\r\n", "\n", $text);

 

Repace \r\n and \r and \n or just \r\n

[line breaks]

Hello I have this code below that converts all types of line breaks to \r\n.

 

$text = preg_replace('#[\r\n]+#', "\n", $text);

 

But if there are 5 line breaks it groups them to 1.  I want to keep the number of line breaks the same, just make them all the same format.    If I remove the + it seems to double the actual number of line breaks.  Can anyone help?

thanks for the help.

[str_replace Help!]

thanks for the help.

[preg_replace explanation of code]

So I could use the code below instead of $text = preg_replace('#[\r\n]+#', "\n", $text);

 

$text = preg_replace('/[\r\n]+/', "\n", $text);

 

and the + means it looks for more than one occurrence of:

 

\r

\n

\r\n

\n\r

 

Or does the + means it will look for the different combinatons which you said were

 

\r

\n

\r\n

\n\r

 

Sorry if question sounds stupid.

[preg_replace explanation of code]

okay, with '#[\r\n]+#', I understand now what it matches but could you explain the hash and the plus in code.

 

Thanks

[preg_replace explanation of code]

Will the expression

 

$text = preg_replace('#[\r\n]+#', "\n", $text);

 

replace \r  and  \n and \r\n or just \r\n

[preg_replace explanation of code]

Could someone please explain how the code below works

 

$text = preg_replace('#[\r\n]+#', "\n", $text);

 

especially the bold part.

 

 

[str_replace Help!]

oni-kun Thanks for the reply but I didn't quite understand your explanation of how I got

 

a\r\r\n\r\nb\r\r\n\r\nc

 

and could someone explain how

 

$text = preg_replace('#[\r\n]+#', "\r\n", $text);

 

works.
