Strings and Arrays (ez question)

[Anon]

How can I read a string into an array, much simillar in the way file($string); does when reading a file into an array. For example.. I want to have all the text in my post put into an array..how would I do that..? thanks..

[Anon]

$myarray=array();
$mytext="Hello World!";
$myarray[0]=$mytext;
echo $myarray[0];
//-> results "Hello World!"

that what you mean?

humm, perhaps I didn't make my self very clear, I'll post the actuall code.. this little script converts htmlchars in a file and makes them perfectly echoed.. what I am tryind to do is instead of it converting a file I want it to convert a string containing text..

$etext = file($ntext);
for ($index = 0; $index < count($etext); $index++)
{
$line = $etext[$index];
//insert forward slash before quotes
$line_coded = ereg_replace("\x22", "\x5c\x22", $line);
//strip carriage returns
$line_coded = ereg_replace("\x0d", "", $line_coded);
//strip line feeds
$line_coded = ereg_replace("\x0a", "", $line_coded);
//change < and > to character entity name for output to HTML page
$line_coded = ereg_replace("<", "&lt;", $line_coded);
$line_coded = ereg_replace(">", "&gt;", $line_coded);
//PHP line of code
$etext = "echo \"$line_coded\n\";\n";
}

Do you see my problem..how can I fix this code?

There are some undefined variables that make this a bit hard to comprehend (what's in file $ntext, for instance?) but it seems that you are looking for explode().

For example:

$input="hello\nworld";
$arr=explode("\n", $input);

Would end up with

$arr[0]=="hello";
$arr[1]=="world";

Thank you I will try explode, my apologies..

in $ntext there are couple of sentences of text.. such as

Hi my name is Joe
Hi my name is Caroline
Hi my name is Goerge

what I want it to do is put each line into an array.. so it would be sometihng like

$ntext[0] would be 'Hi my name is Joe'
$ntext[1] would be 'Hi my name is Caroline' and so on..

thank you..

[Anon]

Try this?

<?PHP

$ntextin=("
Hi my name is Joe
Hi my name is Caroline
Hi my name is Goerge
");

function print_each($ntext) {
foreach ($ntext as $v) {
$ntextout = split("[\n]", "$v");
echo ("$ntextout[0], $ntextout[1], etc..");
}
}

It might work

In my book, explode is easier, best would be file().

<?
$input_file='./somefile.txt';
if ($goods=file($input_file))
foreach($goods as $in) {
$in=trim($in); // to be sure.
print($in);
}
?>

No sorry, that didn't work,
I have tried explode but it seems to only parse the first line and not the rest.. so if it was:
Hi my name is Joe
Hi my name is Caroline
Hi my name is Goerge

It would only parse "Hi my name is Joe"

Thanks for the help, guys, really appreciate it. Hopefully with your help I will find a solution

nemore suggestions?

$etext=explode("\n",$ntext); should work.

I see, though, that in your loop you're replacing the $etext array with a single string (the first line found). I think that's your problem.

for($i=0;$i<count($etext);++$i)
{
//There won't be any "\n" characters in $etext strings - they were exploded out!
$etext[$i]=str_replace("\r",'',$etext[$i]);
$etext[$i]=htmlspecialchars($etext[$i]);
$etext[$i]="echo \"$etext[$i]\\n";\n";
}
