tom100 Posted February 19, 2007 Share Posted February 19, 2007 If it's an actual integer value, PHP will automagically convert it to an integer. You could check if it is a digit or not by using if (ctype_digit($value)) Link to comment https://forums.phpfreaks.com/topic/39220-solved-converting-string-to-int/#findComment-188960 Share on other sites More sharing options...

Jessica Posted February 19, 2007 Share Posted February 19, 2007 you can use intval() to get the integer value, or is_numeric to check if it is. Link to comment https://forums.phpfreaks.com/topic/39220-solved-converting-string-to-int/#findComment-188972 Share on other sites More sharing options...
printf Posted February 19, 2007 Share Posted February 19, 2007 Read the manual, it's self explained, PHP by default is a loosed type language, but it also support dynamic casting, so you should always cast an integer! http://us3.php.net/manual/en/language.types.integer.php#language.types.integer.casting printf Link to comment https://forums.phpfreaks.com/topic/39220-solved-converting-string-to-int/#findComment-188973 Share on other sites More sharing options...
