Description: ------------ Just run the code below and please answer the question: Why those marked as 'warning' generate warning "array_merge_recursive(): recursion detected" while others marked as 'clear' do not? <? // clear echo "<br>example 1"; $a1 = array( 'a' => 1, 'b' => 2 ); $az = array_merge_recursive( $a1, $a1 ); unset( $a1, $a2 ); // clear echo "<br>example 2"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = $a1; $az = array_merge_recursive( $a1, $a2 ); unset( $a1, $a2 ); // clear echo "<br>example 3"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = & $a1; $az = array_merge_recursive( $a1, $a2 ); unset( $a1, $a2 ); // warning echo "<br>example 4"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = & $a1; $a3 = $a1; $az = array_merge_recursive( $a1, $a2 ); unset( $a1, $a2 ); // warning echo "<br>example 5"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = & $a1; $a3 = $a2; $az = array_merge_recursive( $a1, $a2 ); unset( $a1, $a2 ); // warning echo "<br>example 6"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = $a1; $a2[] = 3; // $a2['c'] = 3; - no matter, warning anyway $az = array_merge_recursive( $a1, $a2 ); unset( $a1, $a2 ); // clear echo "<br>example 7"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = & $a1; $a2[] = 3; $az = array_merge_recursive( $a1, $a2 ); unset( $a1, $a2 ); // warning echo "<br>example 8"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = & $a1; $a3 = $a2; $az = array_merge_recursive( $a1, $a3 ); unset( $a1, $a2, $a3 ); // warning echo "<br>example 9"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = $a1; $a3 = & $a2; $az = array_merge_recursive( $a1, $a3 ); unset( $a1, $a2, $a3 ); // clear echo "<br>example 10"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = & $a1; $a3 = & $a2; $az = array_merge_recursive( $a1, $a3 ); unset( $a1, $a2, $a3 ); // warning echo "<br>example 11"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = $a1; $a3 = $a2; $a3[] = 3; $az = array_merge_recursive( $a1, $a3 ); unset( $a1, $a2, $a3 ); // clear echo "<br>example 12"; $a1 = array( 'key1' => 1, 'key3' => 2 ); $a2 = & $a1; $a3 = & $a2; $a3[] = 3; $az = array_merge_recursive( $a1, $a3 ); unset( $a1, $a2, $a3 ); ?> -- Edit bug report at http://bugs.php.net/?id=42177&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42177&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42177&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42177&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42177&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42177&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42177&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42177&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42177&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42177&r=support Expected behavior: http://bugs.php.net/fix.php?id=42177&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42177&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42177&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42177&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42177&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42177&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42177&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42177&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42177&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42177&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42177&r=mysqlcfg
