str_replace for single charachter not working!!!

[the_opposite]

Hi all,

 

I am at a loss to understand why this doesn't work.

I have a simple function:

 

function toHTML($inputText)
{
$inputText = str_replace('<','<',$inputText);
$inputText = str_replace('>','>',$inputText);
$inputText = str_replace('&','&',$inputText);
$inputText = str_replace("'",''',$inputText);
$inputText = str_replace('"','"',$inputText);

return $inputText;
}

 

When I run code through it, specifically xml files from which I need to remove/replace the above charachters, it seems to refuse to replace all of the characters. For example, when I run the following text through this function, the '&' charachter I have highlighted is not replaced:

 

<?xml version="1.0" ?>

The '&' between USB&SATA is not replaced with & on this line:

<ProductName>Freecom Hard Drive Dock 2.5/3.5 USB&SATA</ProductName>

 

Does anybody know why?

 

Thanks in advance

Hi,

First of all your code is wrong because first you replace <, > chars with "&....;" and then you replace the "&" char, so it will replace also & that you put for < and > chars.

And anyway i think that this function is what you are looking for:

Thank you Roman, I wasn't aware of that htmlentities function
