Dear group,
I am a beginner in php and I was little bit experience in C language.
I
want to read a file's content and delete the first line of the file and
display those lines which has got deleted.
The content of the external file , which is in .cvs format is:
-------------------------------------------------------------------
Agency,Ebook,Date,Sold#,Sold$,Refund#,Refund$,GAW#,GAW$,Income
cbezy,Dog,8/7/06,0,0,0,0,204,16.88,-16.88
cbezy,CMS,8/7/06,1,10.79,0,0,0,0,10.79
cbgeo,Sudoku,8/7/06,1,14.72,0,0,0,0,14.72
cbgeo,Cock,8/7/06,1,14.72,0,0,0,0,14.72
ppgeo,Sudoku,8/7/06,17,229.58,2,24.16,2286,118.62,86.8
ppgeo,Pythons,8/7/06,1,19.36,0,0,250,8.84,10.52
ppgeo,Cockatiels,8/7/06,9,108.46,1,16.21,0,0,92.25
ppgeo,Cockatoos,8/7/06,5,72.66,0,0,743,47.56,25.1
ppgeo,Wastewater,8/7/06,1,44.87,0,0,49,5.25,39.62
ppgeo,Chinchillas,8/7/06,1,6.91,0,0,0,0,6.91
ppgeo,Modhomes,8/7/06,0,0,0,0,189,99.94,-99.94
ppgeo,Smormonsub,8/7/06,1,3.54,0,0,0,0,3.54
--------------------------------------------------------------------
The small program which I wrote is
<?php
function read_file($fname)
{
$f = fopen($fname,"r");
if(!$f)
die("file does not exist");
$buff = fread($f,filesize($fname));
if(!$buff)
die("file reading failed");
return $buff;
}
function parse_condent($buff,$fname)
{
$f = fopen($fname, "a+");
if(!$f)
die("file does not exist");
if($buff == '\n' || $buff == '\r' || $buff == '\t') /*####*/
unset($buff);
return $buff;
}
$f = read_file("1.csv");
echo $f.'<br> before delition <br>';
$p = parse_condent($f,"1.csv");
echo $p.'<br> After deletion';
?>
when the line marked with /*####*/ is taken then the whole array is
getting
deleted. I want the specified line and chars. Any help or url link is
appreciated.
<OT>
In C programming the string, which is a pointer is iterated and
checked with
a specified pattern. How is that possible in php?
