Weird behavior PHP vs MySQL - php

Question

This is the SQL:
TRUNCATE TABLE `dc_path`;
INSERT INTO dc_path (coords) VALUES('(40.64406436923055, -8.638539251709062)');
INSERT INTO dc_path (coords) VALUES('(40.62791121610622, -8.615193304443437)');
INSERT INTO dc_path (coords) VALUES('(40.62895347295352, -8.6625718444825)');
If I try to execute that query on phpmyadmin it works just fine, but through php it gives me this error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO dc_path (coords) VALUES('(40.64406436923055, -8.638539251709062)');I' at line 1
I tried many things and I can't work it out!
Thanks in advance.
Edit:
PHP
function insertPath($coords){
$conn = connectDB();
$coords = explode(";",$coords);
$sql = "";
$sql = "TRUNCATE TABLE `dc_path`; ";
for($i=0;$i<count($coords)-1;$i++){
$sql .= "INSERT INTO dc_path (coords) VALUES('".$coords[$i]."');";
}
echo $sql;
$query = mysql_query($sql, $conn) or die(mysql_error());
closeDB($conn);
return true;
}
the $coords variable contains something like these values:
(40.638854101691635, -8.6515855163575);(40.629474595277166, -8.63235944213875);

Answer 1

You cannot perform several queries in one mysql_query() call.
So split that string to 4 separated queries (without ; in the end) and everything will work

Answer 2

Don't use the old mysql_connect API, use mysqli - which supports multiple statements in one.
Read more about the different PHP - mySQL apis here: http://www.php.net/manual/en/mysqlinfo.api.choosing.php
There it says that the old mysql API is not recommended for new projects, and that long term deprecation has been announced.

Answer 3

What function are you using to run this? If you're using mysql_query then you can only do one query at a time, however you can merge the insert statements into one like
INSERT INTO dc_path (coords) VALUES
('(40.64406436923055, -8.638539251709062)'),
('(40.62791121610622, -8.615193304443437)'),
('(40.62895347295352, -8.6625718444825)');

Answer 4

function insertPath($coords){
$conn = connectDB();
$coords = explode(";",$coords);
mysql_query("TRUNCATE TABLE `dc_path`", $conn);
for($i=0;$i<count($coords)-1;$i++){
mysql_query("INSERT INTO dc_path (coords) VALUES('".$coords[$i]."')", $conn);
}
closeDB($conn);
return true;
}

Answer 5

You cannot query more than one statement using mysql_query().
Query like this
for($i=0;$i<count($coords)-1;$i++){
$sql = "INSERT INTO dc_path (coords) VALUES('".$coords[$i]."');";
$query = mysql_query($sql, $conn) or die(mysql_error());
}
