This works
If ($flag != 'u') { stuff.. }
This also works.
If ($id != 0) { stuff.. }
But these don't seem to work for me....
If ( ($flag != 'u') || ($id != 0) ) { stuff.. }
If ( ($flag != 'u') or ($id != 0) ) { stuff.. }
If ($flag != 'u') || ($id != 0) { stuff.. }
If ($flag != 'u') or ($id != 0) { stuff.. }
If ( $flag != 'u' || $id != 0 ) { stuff.. }
If ( $flag != 'u' or $id != 0 ) { stuff.. }
Any idea why? and what format should I use for this in PHP?
Your code actually works. I tried this
<?php
$flag= u;
$id= 0;
if ( ($flag != 'u') || ($id != 0) )
{
echo "Hi";
}
?>
The code simple says if $flag not equal to u or if $id not equals 0 then echo hi in page.
Is that your logic?
The problem might be in your logic I hope!

I have an export to excel button which downloads excel file.
However when i click it shows me error as Trying to access array offset on value of type int
My code is this:
public static function dataTypeForValue($pValue = null)
{
// Match the value against a few data types
if ($pValue === null) {
return PHPExcel_Cell_DataType::TYPE_NULL;
} elseif ($pValue === '') {
return PHPExcel_Cell_DataType::TYPE_STRING;
} elseif ($pValue instanceof PHPExcel_RichText) {
return PHPExcel_Cell_DataType::TYPE_INLINE;
} elseif ($pValue[0] === '=' && strlen($pValue) > 1) { //error comes in this line
return PHPExcel_Cell_DataType::TYPE_FORMULA;
} elseif (is_bool($pValue)) {
return PHPExcel_Cell_DataType::TYPE_BOOL;
} elseif (is_float($pValue) || is_int($pValue)) {
return PHPExcel_Cell_DataType::TYPE_NUMERIC;
} elseif (preg_match('/^[\+\-]?([0-9]+\\.?[0-9]*|[0-9]*\\.?[0-9]+)([Ee][\-\+]?[0-2]?\d{1,3})?$/', $pValue)) {
$tValue = ltrim($pValue, '+-');
if (is_string($pValue) && $tValue[0] === '0' && strlen($tValue) > 1 && $tValue[1] !== '.') {
return PHPExcel_Cell_DataType::TYPE_STRING;
} elseif ((strpos($pValue, '.') === false) && ($pValue > PHP_INT_MAX)) {
return PHPExcel_Cell_DataType::TYPE_STRING;
}
return PHPExcel_Cell_DataType::TYPE_NUMERIC;
} elseif (is_string($pValue) && array_key_exists($pValue, PHPExcel_Cell_DataType::getErrorCodes())) {
return PHPExcel_Cell_DataType::TYPE_ERROR;
}
return PHPExcel_Cell_DataType::TYPE_STRING;
}
}
what can be the solution for this..?
In the PHPExcel file "DefaultValueBinder.php", replace this line 82:
} elseif ($pValue[0] === '=' && strlen($pValue) > 1) {
with the following:
} elseif (0 === strpos($pValue, '=') && strlen($pValue) > 1) {
(!is_int($pValue) && $pValue[0] === '=' && strlen($pValue) > 1) should work. $pValue[0] will not work with integers so check if it is an int or not before continuing.
I update some files in library and It's work fine for me at php 7.4
Please check updated code library :

I'm really confused, because I have an if/else statement what works at a first integration in the system, but in a second case I must rewrite the function. My opinion is, that both statements has the same logic? Or isn't it?
Statement 1: works as intended in first integration of code, but not at the second integration (always the variable ba_geschaeftszeichen has a string lenght of zero):
if (
(isset($_POST['ba_geschaeftszeichen']) && ($kostentraeger == "sozialamt")) ||
(isset($_POST['pk_vnr']) && ($kostentraeger == "pflegekasse"))
) {
if (isset($_POST['ba_geschaeftszeichen']) && (strlen($_POST['ba_geschaeftszeichen']) > 0)) {
$ba_geschaeftszeichen = $_POST['ba_geschaeftszeichen'];
} else if (isset($_POST['pk_vnr']) && (strlen($_POST['pk_vnr']) > 0)) {
$ba_geschaeftszeichen = $_POST['pk_vnr'];
} else {
$ba_geschaeftszeichen = "";
}
} else { $ba_geschaeftszeichen = ""; }
Statement 2: only this code works at the second integration:
if (
(isset($_POST['ba_geschaeftszeichen']) && ($kostentraeger == "sozialamt")) ||
(isset($_POST['pk_vnr']) && ($kostentraeger == "pflegekasse"))
) {
if (isset($_POST['ba_geschaeftszeichen']) && (strlen($_POST['ba_geschaeftszeichen']) > 0)) {
$ba_geschaeftszeichen = $_POST['ba_geschaeftszeichen'];
} else {
$ba_geschaeftszeichen = "";
}
if (isset($_POST['pk_vnr']) && (strlen($_POST['pk_vnr']) > 0)) {
$ba_geschaeftszeichen = $_POST['pk_vnr'];
} else {
$ba_geschaeftszeichen = "";
}
} else { $ba_geschaeftszeichen = ""; }
In statement 1, you reach
if (isset($_POST['pk_vnr']) && (strlen($_POST['pk_vnr']) > 0))
only if
if (isset($_POST['ba_geschaeftszeichen']) && (strlen($_POST['ba_geschaeftszeichen']) > 0))
is false.
In statement 2, you reach
if (isset($_POST['pk_vnr']) && (strlen($_POST['pk_vnr']) > 0))
regardless.
I am trying to add a second condition to existing code but it doesn't seem to be working.
The conditions are:
Compare two strings, from different arrays (working)
And check the value of a third string from a different array (not
working)
Here is the working code without the second condition: http://pastebin.com/bfpNb9zw
Here is my attempt:
Basically, the bit I am trying to get working is this part && ($ca = '') && ($ca = '0') && ($ca = '1') but it seems $ca is not able to be read outside the loop
if(!function_exists('lookup')){
function lookup($chain, $type) {
$cacount = count($chain['tbsCertificate']['extensions']);
for($j = 0; $j < $cacount; $j++) {
$count = count($chain['tbsCertificate'][$type]['rdnSequence']);
$exists = array('utf8String', 'printableString', 'teletexString', 'bmpString', 'universalString', 'ia5String');
$oid = array('id-at-commonName');
for($i = 0; $i < $count; $i++) {
foreach($exists as $field) {
if(
array_key_exists($field, $chain['tbsCertificate'][$type]['rdnSequence'][$i][0]['value']) &&
in_array($chain['tbsCertificate'][$type]['rdnSequence'][$i][0]['type'], $oid)
) {
$value = $chain['tbsCertificate'][$type]['rdnSequence'][$i][0]['value'][$field];
return $value;
$ca = '';
if(isset($chain['tbsCertificate']['extensions'][$j]['extnValue']['cA'])) {
$ca = $chain['tbsCertificate']['extensions'][$j]['extnValue']['cA'];
}
}
}
}
}
return null;
}
}
if (lookup($chain, 'subject') != lookup($chain, 'issuer') && ($ca == '')) {
echo 'end entity';
}
elseif (lookup($chain, 'subject') != lookup($chain, 'issuer') && ($ca == '0')) {
echo 'secondary ca';
}
elseif (lookup($chain, 'subject') != lookup($chain, 'issuer') && ($ca == '1')) {
echo 'primary ca';
} else {
echo 'Root';
}
You are using =, which sets the value of $ca. You should be using === to check the value, instead.
Example:
if (lookup($chain, 'subject') != lookup($chain, 'issuer') && ($ca === '')) {
echo 'end entity';
}
elseif (lookup($chain, 'subject') != lookup($chain, 'issuer') && ($ca === '0')) {
echo 'secondary ca';
}
elseif (lookup($chain, 'subject') != lookup($chain, 'issuer') && ($ca === '1')) {
echo 'primary ca';
} else {
echo 'Root';
}
I'm having some issues with this statement,
<?php
$cert_mess = $vehicle['make'];
if ($vehicle["make"] == "Honda" && $vehicle["Certified"] == "0") {
$cert_mess = "DFWCertAutos";
}
elseif ($vehicle["make"] == "Cadillac" && $vehicle["Certified"] == "0") {
$cert_mess = "DFWCertAutos";
}
elseif (!in_array($vehicle['make'], array('Cadillac','Honda') )) {
$cert_mess = "DFWCertAutos";
}
?>
<div style="font-size:10px; padding:10px; padding-top: 0px;">*This car is <?php
echo $cert_mess ?> certified.</div>
Any suggestions? currently it just displays $cert_mess as 'make' and ignores the if / else if statements.
A simpler code can be the following:
$cert_mess = $vehicle['make'];
if (($vehicle["make"] == "Honda" && $vehicle["Certified"] == "0")
|| ($vehicle["make"] == "Cadillac" && $vehicle["Certified"] == "0")
|| !in_array($vehicle['make'], array('Cadillac','Honda'))
) {
$cert_mess = "DFWCertAutos";
}
Simpler still:
$cert_mess = $vehicle['make'];
if (!in_array($vehicle['make'], array('Cadillac', 'Honda')) || $vehicle['certified'] == '0')
{
$cert_mess = 'DFWCertAutos';
}
Is there any way to go to the else if body after the if condition is sucessfully entered?

If Main IF Statement evaluates true and Inner IF Statement evalautes false then go to Main ELSE IF ladder. If Main IF Statement evaluates true and Inner IF Statement evalautes true then stop loop . If Main IF Statement evaluates false, directly go to Main ELSE IF Statement
If Main ELSE IF Statement evaluates true and Inner IF Statement evalautes false then go to Main ELSE IF ladder. If Main ElSE IF Statement evaluates true and Inner IF Statement evalautes true ,then stop loop .If Main ELSE IF Statement evaluates false, directly go to other Main ELSE IF Statements
Try this:
$success = true;
if($a == $Xaxis && $b == $yaxis) {
$zAxis = $Xaxis + $yaxis;
$success = $Xaxis != $zAxis;
}
if( ($b == $Xaxis && $a == $yaxis) || !$success) {
// do stuff here
}
Or something along those lines.
