string value in array to int

[liquidskin]

Hi all,

 

Im so stuck on this! Cant figure out a solution...

 

$precip_array[0] has a value of "80" in it as a string. I need to compare it to an integer.

 

echo (int)$precip_array[0] returns a "0".  Ive also tried adding a 0 but that results in the same.

 

I did a var_dump on $precip_array[0] which returns string(17) "80"

 

I think 17 signifies the length of the string, but I only see 2 digits when I echo this.  Any help is much appreciated.

Try using trim first?

 

 

echo var_dump(trim($precip_array[0]));

echo var_dump(trim($precip_array[0]));

 

 

 

 

still see 17 chars.

 

also tried

$compareValue = (int)trim($precip_array[0]);

to no avail

It might be easier to troubleshoot if we could see where the array is being given values.

I'm extracting from an XML file.  The 17 characters is the following: <value>77</value>

 

which I'm doing the following to with functions from xml_regex.php

 

$precip = value_in('probability-of-precipitation', $xml);$precip_array = element_set('value', $precip);

finally got it.

$precip_array = element_set('value', $precip,$content_only = true);

 

now I'm only getting 2 chars on the string, which I was able to convert to int and compare.  thanks for getting me thinking, ialsoagree
