I found myself wanting to parse a CSV and didn't have access to str_getcsv, so I wrote substitute for PHP < 5.3, hope it helps someone out there stuck in the same situation.
<?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 = $pos_enclosure_end+3;
} else {
if (empty($pos_delimiter) && empty($pos_enclosure_start)) {
$output[$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."/",$line);
if (is_array($line) && !empty($line[0])) {
$output[$line_num] = $line;
}
}
}
return $output;
} else {
return false;
}
} else {
return false;
}
}
}
?>
