PHP String Manipulation

[ethanhayon]

Hi, I am using PHP to read through emails on a POP3 server. I get the emails out just fine and creates an array of the email by line, but I am trying to remove the "=" that is created when there is a new line.

Here is an example of the output:

PROBLEM CODE: Level 5
PROBLEM: i get a messege that i have exceeded the number of devices that =
i can have

I have tried using this code to solve it:

$text = trim($message,"=");

but that has not worked.

Does anybody have any ideas about how to solve this?

 

Thanks in Advance!

Perhaps something like $text = str_replace("=", " ", $yourArray);

[discomatt]

Perhaps try

 

$line = preg_replace( '/=(?:\\r|\\n)/', '', $line )

[ethanhayon]

Perhaps something like $text = str_replace("=", " ", $yourArray);

 

Ok, that worked fine, but what if the actual message consisted of an "=" sign that i do not want to remove. For example:

 

PROBLEM CODE: Level 5
PROBLEM: i get a messege that says = 0x000021 that i have exceeded the number of devices that =
i can have

I do not want to remove the = that is in the middle of the phrase

Refer to my post, it will only remove = followed by a linebreak character.

when i use that code, nothing happens

You need to use double quotes, not single quotes:

 

$line = preg_replace( "/=(\r|\n)/", '', $line )

It will only work if the = is followed by a linebreak character, so it shouldn't do anything if it isn't followed by the linebreak character. Maybe the syntax is bad. Check your error log.

Then you're giving us bad sample data. It works fine for me. See bottom of post.

No, I don't See below

 

<?php

$data = <<<SAMPLE
PROBLEM CODE: Level 5
PROBLEM: i get a messege that i have exceeded the number of devices that =
i can have
SAMPLE;

$data = preg_replace( '/=(?:\\r|\\n)/', '', $data );

echo $data;

?>

 

Outputs

 

PROBLEM CODE: Level 5
PROBLEM: i get a messege that i have exceeded the number of devices that i can have

 

Which is wrong anyways... here's a fixed version

<?php

$data = <<<SAMPLE
PROBLEM CODE: Level 5
PROBLEM: i get a messege that i have exceeded the number of devices that =
i can have
SAMPLE;

$data = preg_replace( '/=(?=\\r|\\n)/', '', $data );

echo $data;

?>

 

Outputs

I ended up finding a different and simpler solution. This is what I did:

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

[discomatt]

That works as well, assuming your input data is always broken with \r\n and not just \n.

 

But that's doing exactly what my snippet was doing, only mine is slightly more flexible and adapts for a larger range of possible input data.
