(PHP 5, PECL OCI8 >= 1.1.0)
oci_parse — Prepares an Oracle statement for execution
$connection
, string $sql_text
)
Prepares sql_text using
connection and returns the statement identifier,
which can be used with oci_bind_by_name(),
oci_execute() and other functions.
Statement identifiers can be freed
with oci_free_statement() or by setting the
variable to NULL.
connection
An Oracle connection identifier, returned by oci_connect(), oci_pconnect(), or oci_new_connect().
sql_text
The SQL or PL/SQL statement.
SQL statements should not end with a semi-colon (";"). PL/SQL statements should end with a semi-colon (";").
Returns a statement handle on success, or FALSE on error.

<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
// Parse the statement. Note there is no final semi-colon in the SQL statement
$stid = oci_parse($conn, 'SELECT * FROM employees');
oci_execute($stid);
echo "<table border='1'>\n";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {

<?php
/*
Before running the PHP program, create a stored procedure in
SQL*Plus or SQL Developer:
CREATE OR REPLACE PROCEDURE myproc(p1 IN NUMBER, p2 OUT NUMBER) AS
BEGIN

// When parsing PL/SQL programs, there should be a final semi-colon in the string
$stid = oci_parse($conn, 'begin myproc(:p1, :p2); end;');
oci_bind_by_name($stid, ':p1', $p1);
oci_bind_by_name($stid, ':p2', $p2, 40);
oci_execute($stid);
print "$p2\n"; // prints 16
oci_free_statement($stid);
oci_close($conn);
?>
Bilginize:
This function does not validate
sql_text. The only way to find out ifsql_textis a valid SQL or PL/SQL statement is to execute it.
Bilginize:
In PHP versions before 5.0.0 use ociparse() instead. The old function name can still be used in current versions, however it is deprecated and not recommended.
