For example, the following code: <?= rand(10000000000,99999999999); ?> only generates values that start with '12','13' or '14'. Out of 1500 times the function is called, only approx. 1000 different values are generated. Reproduce code: --------------- <?= rand(10000000000,99999999999); ?> Expected result: ---------------- somewhat random numbers between 10000000000 and 99999999999. Actual result: -------------- all numbers are in the range from 120000000000 to 150000000000 and frequently repeat (about 25% of the numbers are repeats). Sample: 1379409636 1275750426 1248288483 1398136354 1404047798 1292410973 1405794269 1278267510 1225653649 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35662&edit=1
