[SOLVED] PHP Notice: Undefined offset:

[rbragg]

I'm getting the PHP Notice:  Undefined offset: error. I am developing a pdf and the problem arises when I wordwrap(). You have to tell the pdf to wrap because new lines are not automatically created, nor are they able to be created with (concatenated) html. The offset number will ALWAYS be the last line.

 

Here is my script:

 

<?php
$display = pdf_findfont($pdf, "Courier", "host", 0); pdf_setfont($pdf, $threeC, ;
pdf_show_xy($pdf, " ", 40, 694);
$stringWrapped = wordwrap($string, 115, "|");
$array = explode("|", $stringWrapped);
$i = 0;
while ($array[$i] != "")
{
pdf_continue_text($pdf, $array[$i]);
$i++;
}
?>

 

So, if this script counts 4 lines, I will get: PHP Notice:  Undefined offset: 4. How can I keep from getting this error other than turning them off on the server? Thanks.

Use a foreach or a for loop instead of the while loop:

Foreach:

<?php
$display = pdf_findfont($pdf, "Courier", "host", 0); pdf_setfont($pdf, $threeC, ;
pdf_show_xy($pdf, " ", 40, 694);
$stringWrapped = wordwrap($string, 115, "|");
$array = explode("|", $stringWrapped);
foreach ($array as $txt)
    if ($txt != "")
pdf_continue_text($pdf, $txt);
?>

 

For:

<?php
$display = pdf_findfont($pdf, "Courier", "host", 0); pdf_setfont($pdf, $threeC, ;
pdf_show_xy($pdf, " ", 40, 694);
$stringWrapped = wordwrap($string, 115, "|");
$array = explode("|", $stringWrapped);
for ($i=0;$i<count($array);$i++)
   if ($array[$i] != "")
pdf_continue_text($pdf, $array[$i]);
?>

The foreach was perfect! Thanks.
