the function posted by hpartidas was an alternative for me in an environment with PHP < 5.3.
However the following if clause (line 20) is wrong:
<?php
// ...
if (empty($pos_delimiter) && empty($pos_enclosure_start)) {
// ...
?>
it should be
<?php
// ...
if (($pos_delimiter === false) && ($pos_enclosure_start === false)) {
// ...
?>
So the corrected function is:
<?php
if (!function_exists('str_getcsv')) {
function str_getcsv($input, $delimiter = ',', $enclosure = '"', $escape
= '\\', $eol = '\n') {
if (is_string($input) && !empty($input)) {
$output = array();
$tmp = preg_split("/".$eol."/",$input);
if (is_array($tmp) && !empty($tmp)) {
while (list($line_num, $line) = each($tmp)) {
if (preg_match("/".$escape.$enclosure."/",$line)) {
while ($strlen = strlen($line)) {
$pos_delimiter = strpos($line,$delimiter);
$pos_enclosure_start = strpos($line,$enclosure);
if (is_int($pos_delimiter) && is_int($pos_enclosure_start)
&& ($pos_enclosure_start < $pos_delimiter) ) {
$enclosed_str = substr($line,1);
$pos_enclosure_end = strpos($enclosed_str,$enclosure);
$enclosed_str = substr($enclosed_str,0,$pos_enclosure_end);
$output[$line_num][] = $enclosed_str;
$offset = $pos_enclosure_end+3;
} else {
if (($pos_delimiter === false) && ($pos_enclosure_start ===
false)) {
$output[$line_num][] = substr($line,0);
$offset = strlen($line);
} else {
$output[$line_num][] = substr($line,0,$pos_delimiter);
$offset = ( !empty($pos_enclosure_start) &&
($pos_enclosure_start < $pos_delimiter) ) ? $pos_enclosure_start : $pos_delimiter+1;
}
}
$line = substr($line,$offset);
}
} else {
$line = preg_split("/".$delimiter."/",$line);
/*
* Validating against pesky extra line breaks creating false rows.
*/
if (is_array($line) && !empty($line[0])) {
$output[$line_num] = $line;
}
}
}
return $output;
} else {
return false;
}
} else {
return false;
}
}
}
